Theoretical Foundation
Estrogen is the primary trigger for epiphyseal fusion through Estrogen Receptor Alpha activation in chondrocytes, which accelerates plate closure and increases the apoptosis rate in proliferative chondrocytes. By moderately suppressing E2 via an irreversible aromatase inhibitor, this closure trigger is attenuated – however, minimal E2 remains necessary since chondrocyte proliferation itself is E2-dependent. Simultaneously, testosterone rises by approximately 30–60% above baseline due to reduced estrogen feedback on the HPG Axis.


Prerequisites
- Growth plates confirmed still open via X-Ray
- Baseline bloodwork: E2, Testosterone, DHT, IGF-1, Calcium, Liver Enzymes
- DEXA Scan as baseline
- No pre-existing hypogonadism

Phase 1 – Weeks 1–2: Ramp Up​

Compound	Dose	Frequency	Timing	Purpose
Exemestane	12.5mg	EOD	Morning with food	Irreversible aromatase inhibitor – permanently binds and destroys aromatase enzyme, reducing E2 production. Low starting dose to avoid abrupt E2 crash while body adapts
Vitamin D3	5000 IU	daily	Morning with food	Maximizes intestinal calcium absorption and keeps PTH suppressed from day one, preventing early osteoclast overactivation
Vitamin K2 MK-7	200mcg	daily	Morning with food	Directs calcium into bone tissue rather than soft tissue or arteries – essential companion to high-dose D3
ALCAR	1000mg	daily	Morning with food	Transports fatty acids directly into mitochondria, bypassing blocked glucose pathways – provides stable slow-burning brain energy as E2 begins to drop
MCT Oil	20ml	daily	Morning with food	Rapidly converted to ketone bodies in the liver, entering the brain via a completely separate unlocked metabolic pathway – fast-acting complementary energy source to ALCAR

Bloodwork after Week 2:
- E2 target range: *20–30 pg/ml*
- Testosterone: document baseline
- DHT: document baseline

Phase 2 – Weeks 3–10: Main Cycle:​

Compound	Dose	Frequency	Timing	Purpose
Exemestane	25mg	EOD	morning with food	Full therapeutic dose – maintains consistent aromatase suppression. EOD timing aligns with aromatase enzyme regeneration cycle of ~48h, preventing E2 from recovering between doses
Vitamin D3	5000IU	daily	morning with food	Ongoing PTH suppression and calcium absorption optimization – bone protection throughout the cycle
Vitamin K2 MK-7	200mcg	daily	morning with food	Ongoing calcium redirection into bone – prevents arterial calcification from sustained high-dose D3
ALCAR	1000mg	daily	morning with food	Sustained alternative brain fuel – glucose pathways remain chronically impaired at full E2 suppression, ALCAR compensates with mitochondrial fatty acid transport
MCT-Oil	20ml	daily	morning with food	Sustained fast-acting ketone energy source – works synergistically with ALCAR to fully replace blocked glucose metabolism in the brain
EGCG	400mg	daily	30min before dinner	Temporarily inhibits peripheral AAAD enzymes in gut and bloodstream before 5-HTP intake – prevents premature conversion of 5-HTP outside the brain, maximizes delivery to CNS and prevents severe nausea
5-HTP	100mg	daily	evening after food	Directly bypasses the frozen TPH2 assembly line – delivers serotonin precursor straight to the brain without requiring the first conversion step that E2 normally facilitates
P5P	20mg	daily	evening after food	Acts as direct co-factor for the AAAD enzyme – without P5P the conversion of 5-HTP to active serotonin runs inefficiently regardless of 5-HTP availability
Bacopa Monnieri 50% Bacosides	600mg	daily	evening after food	Triggers BDNF/NGF cascade activating LIMK, which places a direct off-switch on cofilin and halts actin destruction in the hippocampus. Simultaneously acts as PAM, restoring sensitivity of downregulated serotonin receptors
Lithium Orotate	5mg	daily	evening after food	Inhibits HDAC and keeps epigenetic gates in brain cells open – ensures cellular repair processes, BDNF production and cell growth remain continuously active throughout the cycle

E2 Target Range: 15–25 pg/ml
Below 15 pg/ml → Reduce dose to 12.5mg EOD
Above 35 pg/ml → Increase frequency to daily

Testosterone Target Range: below 1200 ng/dl
Above 1200 ng/dl → Slightly reduce Exemestane dose as residual aromatase activity at very high testosterone levels will undermine E2 suppression

DHT Monitoring:
DHT rises in parallel with testosterone via 5-Alpha Reductase – not a direct stop criterion but a relevant additional fusion trigger through androgen receptors in chondrocytes. Remains unmitigated in this stack.

Bloodwork Week 6: E2, Testosterone, DHT, IGF-1, Calcium, Liver Enzymes

Phase 3 - Weeks 11-12: Taper​

Compound	Dose	Frequency	Timing	Purpose
Exemestane	12.5mg	EOD	Morning with food	Gradual dose reduction allows aromatase population to slowly regenerate – prevents abrupt E2 rebound that would occur if Exemestane were stopped suddenly after 10 weeks of full suppression
All other Compounds	Same dose	same	same	-

Testosterone begins normalizing during this phase as GnRH pulses reduce in response to gradually rising E2.

Off Cycle – Weeks 13–18: Pause & Recovery
Minimum duration: 6 weeks:
​

System	Approx. Required Recovery Time
Aromatase population	2 weeks
Testosterone normalization	2-3 weeks
DHT normalization	2-3 weeks
Bone remodeling initiation	3-4 weeks
IGF1 Axis renormalization	4 weeks
Hippocampus	6 weeks

Compound	Dose	Frequency	Timing	Purpose
Vitamin D3	5000IU	daily	Morning with food	Bone recovery requires continued calcium optimization even after Exemestane is stopped – osteoblast activity needs adequate calcium supply to rebuild what osteoclasts broke down
Vitamin K2 MK-7	200mcg	daily	Morning with food	Morning with food | Ensures calcium continues to be directed into bone during recovery phase rather than accumulating in soft tissue
ALCAR	1000mg	daily	Morning with food	Brain energy normalization takes several weeks as glucose pathways gradually reopen with recovering E2 – ALCAR bridges this gap
Bacopa Monnieri	600mg	daily	Evening	BDNF-mediated hippocampus repair is most effective during sleep and continues accumulating over 6 weeks – stopping Bacopa immediately after cycle would interrupt ongoing structural repair

Green light for next cycle only if:
- E2 back in normal range *25–40 pg/ml*
- Testosterone normalized
- DHT normalized
- IGF-1 normalized
- Calcium normalized
- Liver enzymes within normal range
- DEXA shows less than *5% bone density loss* versus baseline

Monitoring Protocol​

Timepoint	Parameters
before Cycle start	E2, testosterone, DHT, IGF-1, Calcium, Vitamin D, Liver Enzymes, DEXA Scan
Week 2	E2, Testosterone, DHT, Calcium
Week 6	E2, Testosterone, DHT, Calcium, Liver Enzymes, IGF-1
Week 12	Full bloodwork
Week 18	Full Bloodwork plus DEXA scan

Potential Benefits: (NOTHING is garuanteed)​

Benefit	Mechanism
Prolonged growth plate window	Reduced Estrogen Receptor Alpha stimulus slows epiphyseal fusion
Elevated testosterone	Supports collagen synthesis and bone formation via androgen receptors
More stable GH/IGF-1 Axis	Moderate E2 reduction may improve GH pulse amplitude
0.5–1cm per cycle	Extrapolated from pediatric AI studies
Cumulatively up to 2.5cm over 4 cycles	Only if plates remain active and monitoring confirms safety

Risks and Mitigation:​

Risk	Likelihood	Severity	Mitigated by Stack?
Bone Density loss	very high	high	Partially – D3 + K2 slow but do not eliminate
Brain fog / glucose pathway blockade	high	moderate	Yes – ALCAR + MCT Oil fully
Serotonin dysregulation	high	moderate	Yes – 5-HTP + P5P + EGCG fully
Hippocampus stress	moderate	moderate	Largely – Bacopa + Lithium Orotate
DHT elevation -> additional fusion trigger	moderate	moderate	no- unmitigated
IGF-1 disruption	moderate	moderate	no - no direct mitigation in stack
liver enzyme elevation	moderate	moderate	no - monitoring only
Libido decline	high	moderate	partially
E2 crash below 10pg/ml	moderate	high	detectable via week2 bloodwork
irreversible bone damage	low with monitoring	very high	controllable via DEXA only

Absolute Stop Criteria
- E2 below 15 pg/ml despite dose reduction
- DEXA shows more than 5% bone density loss
- Liver enzymes exceed 3x upper limit of normal
- Testosterone persistently above 1200 ng/dl despite dose adjustment
- X-Ray confirms complete fusion of all relevant growth plates
- Psychological symptoms uncontrollable despite full stack

Complete Timeline Overview​

Period	Phase
Weeks 1-2	Ramp up - 12.5mg EOD
Weeks 3-10	Main Cycle - 25mg EOD
Weeks 11-12	Taper - 12.5mg EOD

Rep this shit, I sat so many hours on this. Sometimes I used tools to translate my language to english, sorry for any special words that sound weird. Thank you for reading.

raloxifene fixes bone density issues, acts like estrogen in the bone shaft excluding the epiphysial plates (i could be wrong im low iq)

 

[mewzilla]

also why no gh

 

[unknownlarp]

also why no gh

More side effects to deal with. If my first Cycle goes well I might consider hopping on hgh. I need to do more research for that also.
