SECTION 1: ESTROGEN MANAGEMENT
The Basics
Testosterone and most of its derivatives aromatize to estradiol (E2) via CYP19A1 (aromatase). E2 is not your enemy at physiological levels since it's critical for libido, bone density, joint health, lipid metabolism, neurological function, and cardiovascular protection. The goal is always management, never suppression.
Symptoms of high E2: water retention, soft fat gains, sensitive/puffy nipples, emotional blunting, low libido paradoxically
Symptoms of low E2: joint pain, dry skin, zero libido, depression, brain fog, weak erections despite high androgens
Both feel terrible. The sweet spot for most males is around 20-35 pg/mL on sensitive assay
Anastrozole (generic Arimidex)
Reversible non-steroidal competitive aromatase inhibitor. Binds CYP19A1 and blocks androgen-to-estrogen conversion. Half-life approx. 46 hours. Once daily or EOD dosing works fine.
Main risk: because inhibition is reversible, stopping anastrozole causes a rapid return of aromatase activity and a sharp E2 rebound. Can cause transient gyno flare if stopped abruptly while androgen levels still high.
Also worth knowing: anastrozole reduces bone mineral density with long-term use. Not relevant for typical cycle lengths but worth knowing if using for extended periods.
Exemestane (generic Aromasin)
Steroidal irreversible ("suicidal") aromatase inhibitor. Permanently deactivates each enzyme molecule it binds. New aromatase protein must be synthesized, making rebound far smoother and more gradual. Has weak androgenic activity via its steroidal structure
Exemestane also has a small but documented positive effect on bone mineral density compared to anastrozole, because its androgenic metabolites partially compensate.
Letrozole
Most potent AI out there, near complete suppression at clinical doses. Half-life approx. 48 hours. Occasionally useful for established gyno flare-ups at short-term high doses (2.5mg/day for 1-2 weeks), but not for routine cycle E2 management. Crashing E2 to near zero feels genuinely terrible and tanks lipids hard.
Which compounds require an AI:
- Testosterone (all esters) ✓
- Nandrolone (low aromatization, but some) light AI at most
- Boldenone (moderate aromatization) ✓
- Dianabol (aromatizes heavily, rapid) ✓
- Tren does NOT aromatize, no AI needed for estrogen
- DHT derivatives (Masteron, Winstrol, Proviron, Anavar, Halo) do NOT aromatize, no AI needed
Budget verdict: Generic anastrozole or exemestane. Start when symptomatic or bloods show >40 pg/mL. Dont start day 1 of cycle. 0.25-0.5mg anastrozole EOD or 12.5-25mg exemestane EOD is plenty for most people at moderate doses.
SECTION 2: PROLACTIN & PROGESTERONE MANAGEMENT
When is this relevant:19-nor compounds like nandrolone (Deca) and trenbolone. Both have significant progesterone receptor activity. Progesterone sensitizes breast tissue to estrogen, meaning gyno can develop even with E2 well controlled. Additionally, progestogenic activity elevates prolactin via dopaminergic pathway suppression.
High prolactin symptoms: nipple discharge (galactorrhea), gyno, low libido, sexual dysfunction, emotional blunting.
Cabergoline (generic Dostinex)
D2 receptor agonist. Suppresses prolactin secretion from anterior pituitary lactotrophs. Half-life approx. 65-70 hours, twice weekly dosing is sufficient. Extremely well-studied clinically (used for prolactinomas for decades). Generic is inexpensive.
Side effects: nausea (take with food, dose at bedtime), rare cardiac valvulopathy at very high long-term doses used for Parkinson's, completely irrelevant at cycle support doses.
Bromocriptine
Older D1/D2 agonist. Shorter half-life, more side effects, worse tolerability. Cabergoline is strictly superior in every way. Only mention it because it's occasionally cheaper in certain markets.
Budget verdict: Caber 0.25mg twice weekly if running nandrolone or tren. Get prolactin bloods and if it's not elevated, you may not need it at all at moderate doses.
SECTION 3: CARDIOVASCULAR SUPPORT
This is the most neglected and most important category. Cardiovascular damage is the primary long term risk of AAS use and most retards do almost nothing to mitigate it.
Telmisartan (generic)
ARB (angiotensin II receptor blocker). Already covered partially, going deeper here.
Mechanism 1 - Blood Pressure: Blocks AT1 receptor, prevents angiotensin II-mediated vasoconstriction and aldosterone secretion. Androgens raise BP through sodium retention, increased RBC mass increasing blood viscosity, and increased cardiac output. Telmisartan's 24-hour half-life gives better around-the-clock coverage than most other ARBs.
Mechanism 2 - PPARγ partial agonism: Telmisartan is unique among ARBs in being a selective PPARγ modulator. This gives it:
- Improved insulin sensitivity (relevant because supraphysiological androgens can impair glucose metabolism)
- Favorable adipokine profile
- Anti-inflammatory effects independent of BP lowering
Mechanism 3 - Cardiac remodeling: The renin-angiotensin system drives pathological left ventricular hypertrophy (LVH). Androgen induced LVH has both physiological (concentric, from increased cardiac output demand) and pathological components. AT1 blockade specifically blunts the pathological fibrotic remodeling that is the dangerous component.
Budget verdict: Generic telmisartan 20-40mg once daily. If BP consistently above 130/85 on cycle, this is mandatory. Even at normal BP, telmisartan has an argument as a prophylactic cardioprotective on heavy/long cycles based on its non-BP mechanisms. One of the most underused and most important ancillaries.
Tadalafil 5mg daily (generic Cialis)
Already covered basics. Going deeper:
Endothelial function: PDE5 inhibition increases NO (nitric oxide) availability via cGMP upregulation. Chronic endothelial dysfunction is an early marker of cardiovascular disease. Daily low-dose tadalafil demonstrably improves flow-mediated dilation (FMD), the gold standard measure of endothelial function.
Pulmonary arterial pressure: High hematocrit and increased cardiac output can raise pulmonary pressures. PDE5 inhibitors are first-line clinical treatment for pulmonary arterial hypertension, the same mechanism provides protective effects at cycle-relevant doses.
Cardiac hypertrophy: Emerging evidence suggests PDE5 inhibition blunts pathological cardiac hypertrophy through cGMP PKG signaling in cardiomyocytes separate from its vascular effects.
Prostate: Daily tadalafil 5mg is FDA-approved for BPH/LUTS. DHT driven androgens (testosterone, especially DHT derivatives) cause prostate enlargement. This is relevant on long cycles with heavy androgen load.
Budget verdict: Generic tadalafil 5mg daily. Covers endothelial function, pulmonary pressure, cardiac remodeling, prostate, and libido/sexual function simultaneously. One of the cheapest ancillaries with the most overlapping benefits. Should be on every cycle regardless of compounds.
Low-dose Aspirin (81mg enteric coated)
Androgen-driven erythropoiesis raises hematocrit. Elevated hematocrit increases whole blood viscosity in a non-linear fashion, small increases above 52% disproportionately increase thrombotic risk.
Aspirin irreversibly acetylates platelet COX-1, preventing thromboxane A2 synthesis and platelet aggregation. Effect lasts platelet lifetime (7-10 days) so daily dosing maintains effect through platelet turnover.
Important: aspirin does NOT lower hematocrit. If hematocrit exceeds 52%, donate blood, aspirin is not a substitute for this. It reduces clotting risk but doesn't address the underlying viscosity issue.
GI risk with chronic aspirin use is real. Take enteric coated with food. Avoid with history of GI ulcers.
Budget verdict: 81mg enteric coated daily, costs almost nothing. Stack with talmisartan and tadalafil for overlapping cardiovascular protection.
Berberine - budget insulin sensitizer
Supraphysiological androgens impair insulin signaling over time. Glucose metabolism suffers especially when eating in significant surplus. Berberine is an AMPK activator with clinical evidence for glucose lowering comparable in magnitude to metformin in some trials.
Mechanism: activates AMPK (AMP-activated protein kinase), increases GLUT4 translocation to cell membrane, improves insulin receptor sensitivity, reduces hepatic glucose output.
Also has meaningful lipid lowering effects, reduces LDL via upregulation of LDLR expression and inhibition of PCSK9.
AAS, especially orals and DHT derivatives, hammer lipids hard. Berberine addressing both glucose metabolism and LDL makes it genuinely multi-purpose on cycle.
Budget verdict: 500mg three times daily with meals (timing with meals matters for glucose effects). Cheap, widely available, two distinct mechanisms relevant to cycle use.
Coenzyme Q10 (CoQ10)
Electron transport chain cofactor, essential for mitochondrial ATP production. Cardiac muscle is the most mitochondria-dense tissue in the body and consequently most affected by CoQ10 depletion.
AAS use increases cardiac oxidative stress. CoQ10 functions as a mitochondrial antioxidant in addition to its ETC role. Clinical studies show CoQ10 supplementation reduces markers of cardiac oxidative stress and improves diastolic function in various cardiac conditions.
Budget verdict: 200-400mg/day ubiquinol form (more bioavailable than ubiquinone). Not cheap but not expensive. More relevant on heavier, longer cycles where cardiac strain is a genuine concern.
SECTION 4: HEMATOCRIT / RBC MANAGEMENT
Androgens stimulate EPO production renally and directly stimulate erythropoiesis in bone marrow via androgen receptor activation on erythroid progenitors. Hematocrit consistently rises on cycle, particularly with testosterone and tren.
Target: keep hematocrit below 52%. Above this, viscosity increases nonlinearly and thrombotic risk rises significantly.
Tools:
Therapeutic phlebotomy (blood donation): Most effective intervention. Donating 450-500mL removes approximately 200-250mg of iron and acutely reduces hematocrit by ~3%. Free at donation centers. Do not donate more than once every 8 weeks ideally. Check if your donation center allows frequent donation.
Hydration: Plasma volume expansion through adequate hydration dilutes hematocrit. Basic but it works. Chronically dehydrated guys consistently read higher hematocrit on bloods. Drink water.
Avoid altitude: Higher altitudes drive additional EPO release. If your bloods are borderline, this matters.
Aspirin: As above, doesn't lower hematocrit but reduces thrombotic risk from elevated viscosity.
Telmisartan: Some evidence ARBs modestly reduce EPO-driven erythropoiesis via AT1 blockade in renal EPO-producing cells. Effect is modest but present.
Budget verdict: Blood donation is free and the most effective tool. Stack with hydration, aspirin, and telmisartan. Monitor hematocrit on every bloodwork panel.
SECTION 5: LIVER SUPPORT
Only relevant with hepatotoxic oral compounds:17α-alkylated orals: Anadrol (oxymetholone), Winstrol (stanozolol), Dianabol (methandrostenolone), Halo (fluoxymesterone), Superdrol (methyldrostanolone), M1T
Non-hepatotoxic: all injectable compounds, Anavar (very mild), Proviron
TUDCA (Tauroursodeoxycholic acid)
Hydrophilic bile acid. Hepatoprotective via multiple mechanisms:
- Reduces ER stress in hepatocytes
- Inhibits mitochondrial apoptotic pathway (Bax/Bcl-2 modulation)
- Promotes bile flow, reducing cholestatic buildup caused by 17α-alkylated compounds
- Anti-inflammatory in hepatic tissue
500mg/day during oral use. Run it the entire duration of oral compound use. Not cheap but genuinely necessary with hepatotoxic orals.
NAC (N-Acetylcysteine)
Glutathione precursor. Glutathione is the primary endogenous hepatic antioxidant. 17α-alkylated compounds deplete hepatic glutathione. NAC replenishes it.
Also has direct free radical scavenging activity and anti-inflammatory effects independent of glutathione.
600mg twice daily. Cheap, widely available, complements TUDCA through entirely different mechanism.
Milk thistle (Silymarin)
Silibinin (active component) is a flavonoid with antioxidant and mild hepatoprotective properties. Evidence is weaker than TUDCA/NAC and the effect size is smaller. But it's extremely cheap and has supportive mechanisms and can be added as a cheap layer.
Budget verdict on liver stack: TUDCA 500mg + NAC 600mg twice daily. Add milk thistle if budget allows. Do NOT run hepatotoxic orals without liver support. Get ALT/AST bloods midway through oral use.
SECTION 7: HAIR / SCALP PROTECTION
Only relevant if genetically predisposed (norwood progression in family). DHT is the primary driver, 5AR type II converts testosterone to DHT in scalp follicles, causing miniaturization in genetically sensitive follicles.
Finasteride
5-alpha reductase type II inhibitor. Reduces DHT by approx. 70% systemically. Generic is cheap. Very effective for MPB prevention.
Relevant compounds: testosterone, any compound that converts to DHT or is already DHT-derived worsens hair loss in predisposed individuals.
Important: finasteride doesn't help with DHT-derivative compounds (Masteron, Winstrol, Anavar, Halo, Proviron) because these are already derived from DHT and don't require 5AR conversion, finasteride has no effect on them.
Also: 5AR inhibitors reduce the neurosteroid allopregnanolone (GABA-A modulator), mood/sexual side effects in a subset of users. This is real and underacknowledged.
RU58841 (research compound)
Topical androgen receptor antagonist. Applied directly to scalp, minimal systemic absorption. Blocks AR in scalp follicles locally without systemic DHT reduction.
Nizoral (Ketoconazole shampoo)
Weak AR antagonist, antifungal, reduces scalp inflammation. Complements finasteride/RU58841. Use 3x/week.
Minoxidil
Potassium channel opener, promotes scalp blood flow, prolongs anagen phase, independent of DHT pathway. Complements finasteride by working through different mechanism. Generic foam or solution is cheap. Oral is even better, might be available only with a prescription in most countries, but there are multiple sources that sell oral minoxidil, for extremely cheap.
Budget verdict: Finasteride is cheap. Stack with Nizoral 2% shampoo and minoxidil if concerned about hair. RU58841 if running DHT-derivatives where finasteride is ineffective.
SECTION 8: SLEEP & CNS / NEUROLOGICAL SUPPORT
Tren in particular is notorious for sleep disruption, night sweats, insomnia, vivid dreams, anxiety. Partially GR-mediated (glucocorticoid receptor activity in HPA axis) and partially androgenic CNS effects.
Melatonin
Chronobiotic, not a sedative. Regulates circadian rhythm. Supraphysiological androgens and night sweats disrupt sleep architecture. Melatonin helps reset and maintain circadian signaling.
0.5-1mg is the evidence-supported dose, most commercial tablets are 5-10mg which is supraphysiological and can cause next-day grogginess and paradoxically disrupt circadian rhythm with chronic use.
Magnesium Glycinate
NMDA receptor modulator, GABAergic activity, involved in 300+ enzymatic reactions. Genuinely reduces anxiety, improves sleep quality, reduces muscle cramps (relevant on cycle). Glycinate form has highest bioavailability and lowest GI side effects.
400mg before bed. Cheap.
Ashwagandha (KSM-66)
Adaptogen, cortisol modulator. Reduces cortisol via HPA axis modulation, reduces anxiety, improves sleep quality. Has small but real testosterone-raising effect in eugonadal men (irrelevant on cycle but the cortisol effects matter).
Mechanism includes GABA-mimetic activity and direct cortisol reduction at adrenal level.
Budget verdict: Melatonin 0.5mg + magnesium glycinate 400mg covers most sleep issues. Add ashwagandha if tren anxiety/cortisol is a real issue. All cheap. AVOID benzos or Z-drugs for on-cycle insomnia, dependence risk and they suppress REM.
SECTION 9: JOINT SUPPORT
Compounds like Winstrol and Masteron crash E2 (or worsen low E2 from over-AI use) causing severe joint pain. Anavar and some DHT derivatives do the same. Also just the increased training load on cycle beats up connective tissue.
The first fix: don't crash E2
Most "joint pain on Winstrol" is just low E2. Fix your AI dose first.
Glucosamine Sulfate + Chondroitin
Cartilage matrix precursors. Reduce joint degradation, modest anti-inflammatory effect, maintain synovial fluid quality. Long-term benefits documented for knee OA, relevant as a prophylactic during high-volume heavy training.
1500mg glucosamine sulfate + 1200mg chondroitin daily. Takes 4-8 weeks to see meaningful effect.
Collagen peptides + Vitamin C
Collagen synthesis in tendons and ligaments requires vitamin C (ascorbate) as cofactor for prolyl hydroxylase. Supplementing hydrolyzed collagen with vitamin C before training increases markers of collagen synthesis in tendons.
10-15g collagen peptides + 50mg vitamin C taken 30-60 minutes before training. Cheap and underused.
Budget verdict: Fix E2 first. Stack glucosamine/chondroitin + collagen peptides for connective tissue support. Both cheap and have decent evidence.
SECTION 10: LIPID MANAGEMENT (DETAILED)
AAS use, especially orals and DHT derivatives, devastates the lipid panel. HDL tanks, LDL rises, triglycerides can rise. This is one of the most consistent cardiovascular risk factors from AAS use.
High-dose Fish Oil (EPA/DHA)
3-4g EPA+DHA per day. Reduces triglycerides significantly (up to 30-40% reduction), modest HDL raising, anti-inflammatory via competitive inhibition of arachidonic acid metabolism.
Buy concentrated fish oil (60%+ EPA/DHA). Standard supermarket capsules at 30% concentration require 10+ pills to hit therapeutic dose.
Berberine
As covered in cardiovascular section, also reduces LDL via LDLR upregulation and PCSK9 inhibition. Genuinely meaningful effect size on LDL. Stack with fish oil for complementary mechanisms.
Niacin (Vitamin B3 - flush form)
High-dose niacin is one of the most potent HDL-raising agents available. Mechanism involves inhibiting hepatic HDL clearance and reducing hepatic triglyceride synthesis. 500-1000mg extended-release.
Flushing side effect is prostaglandin-mediated, take aspirin 30 minutes before to reduce flush. Takes time to build up. Inositol hexanicotinate ("no-flush niacin") has much weaker lipid effects - not worth using.
Red Yeast Rice
Contains monacolin K, which is structurally identical to lovastatin. Reduces LDL via HMG CoA reductase inhibition (same mechanism as statins). Relevant if LDL is badly elevated on cycle.
Caution: same side effect profile as statins (myopathy risk) at higher doses. Take CoQ10 alongside.
Budget verdict: Fish oil + berberine is the core lipid stack. Add niacin if HDL is tanked from oral use. Get a full lipid panel every cycle.
SECTION 11: Bloodwork
The minimum non negotiable panels:
Hormonal:
- Total testosterone
- Free testosterone (calculated or equilibrium dialysis)
- SHBG
- Estradiol sensitive (LC-MS/MS, NOT immunoassay)
- LH + FSH (suppression marker)
- Prolactin (always if running 19-nors)
- DHT (optional but informative on DHT-heavy cycles)
- IGF-1 (if running GH)
Cardiovascular/Metabolic:
- CBC with differential (hematocrit, hemoglobin, RBC, WBC, platelets)
- Comprehensive metabolic panel (sodium, potassium, creatinine, BUN, glucose)
- Full lipid panel (LDL, HDL, total cholesterol, triglycerides, ideally ApoB)
- HbA1c (if running long or eating aggressively. insulin resistance marker)
- Homocysteine (inflammatory cardiovascular marker, elevated by B vitamin deficiency)
- hsCRP (high-sensitivity C-reactive protein. inflammatory marker)
Liver:
- ALT + AST
- GGT (more sensitive than ALT/AST for hepatic stress in some cases)
- Bilirubin
- Albumin
Blood Pressure:Buy a home upper arm cuff. Monitor BP weekly minimum. Log it. This is the most important thing most people never do.
Timing: baseline bloods before cycle, mid-cycle bloods (especially for first time with a compound), and post-cycle bloods 6-8 weeks after.
Budget Priority Stack (ranked by importance/cost efficiency)
- Bloodwork + home BP monitor - non-negotiable
- Generic tadalafil 5mg daily -cardiovascular, endothelial, prostate, libido
- Generic AI (anastrozole or exemestane) - if running aromatizing compounds
- Aspirin 81mg enteric coated daily - thrombotic risk, almost free
- High-dose concentrated fish oil - lipids, inflammation
- Generic telmisartan 20-40mg - if BP elevated
- Berberine 500mg 3x/day - lipids + insulin sensitivity
- Magnesium glycinate 400mg + Melatonin 1mg/before sleep - sleep, cramps
- Cabergoline - only on 19-nors
- HCG 250-500 IU E3-4D - testicular maintenance
- TUDCA 500mg + NAC 600mg - only on hepatotoxic orals
- CoQ10 ubiquinol 200-400mg - cardiac mitochondrial support on heavier cycles
- Glucosamine/Chondroitin + Collagen peptides - joints/connective tissue (make sure E2 is in range though, or these won't do much)
- Finasteride + Nizoral - only if hair is a concern
Stop buying "cycle support" products. They are simply cope. Every ingredient in them is available generically for a fraction of the price.
