Hi, I wanna to learn more about a few compounds. I’ll send them below.
Has anyone actually grown from this, and can it at least support height growth? Also, could it be a double-edged sword and potentially accelerate growth-plate closure?
Like this for example?
Abaloparatide 80 µg ED (until plates close)
Meclizine 25 mg ED (PM)
Lithium Orotate 20 mg ED
Epitalon 5 mg daily × 10 days → 20 days off
Vesugen 5 mg daily × 10 days → 20 days off
Senolytics – Fisetin 2 g + Quercetin 1 g ED for 2 days 1×/month (no antioxidants those 2 days)
Cartalax 1 mg daily
EPO 1000 IU × 2 per week
Thymalin 5 mg × 10 days / month (support runx1)
Support:
Glow stack
Ergothioneine 5 mg
Silicon (Orthosilicic Acid) 20 mg ED
PQQ 20 mg
MCHA Calcium+Phosphate (am)
Strontium Citrate 680 mg (pm)

1. HDAC Inhibitors (Vorinostat) - Epigenetic Bone Enhancement
Histone deacetylase (HDAC) inhibitors, such as vorinostat (SAHA), have shown promise in promoting osteoblast differentiation and bone formation.
Mechanism: HDAC inhibitors modify gene expression, increasing RUNX2 activity (a key transcription factor for osteoblast differentiation).
Research: Studies indicate that HDAC inhibition reduces bone resorption while stimulating new bone formation, making it useful for osteoporosis and fracture healing.
Dosage: Vorinostat is typically used at 50-100 mg/day in clinical settings, but lower doses (10-25 mg) may suffice for bone-specific effects.
Considerations: HDAC inhibitors can have systemic effects, so cycling (e.g., 2 weeks on/2 weeks off) may be optimal.
---
2. Anabolic Steroids (Oxandrolone/Anavar) - Strong Bone Stimulation
Anavar (oxandrolone) is one of the best steroids for bone mineral density (BMD) due to its low androgenic side effects and strong anabolic activity.
Mechanism:
• Increases IGF-1 (critical for bone growth).
• Stimulates osteoblasts directly via androgen receptor activation.
• Reduces bone resorption by suppressing osteoclast activity.
Dosage: 10-20 mg/day is sufficient for bone benefits without significant liver strain.
Synergy: Combines well with PTH analogs and GH for enhanced bone formation.
Note: Other steroids like nandrolone (increases collagen synthesis) and testosterone (converts to estrogen, which protects bones) can also be beneficial.
---
3. Parathyroid Hormone (PTH) Analogs - The Gold Standard for Bone Growth
Teriparatide (Forteo) is an FDA-approved PTH(1-34) analog that dramatically increases bone density by stimulating osteoblasts.
Mechanism:
• Intermittent PTH (daily injections) boosts osteoblast activity.
• Increases calcium absorption in the gut and kidneys.
Dosage: 20 mcg/day subcutaneously (standard protocol).
Cycling: Limited to 18-24 months due to osteosarcoma risk (rare).
Alternative: Abaloparatide (a modified PTHrP analog) may be even more potent.
---
4. Aromatase Inhibitors (AIs) - Epiphyseal Plate Closure
Inhibiting estrogen is important for preventing/delaying epiphyseal plate closure to ensure that the long bones (arms, legs, spine, clavicles) remain in growth phase for longer.
---
5. Growth Hormone (GH) & IGF-1 - Critical for Bone Elongation & Density
GH and IGF-1 are essential for bone elongation (epiphyseal plate stimulation) and collagen synthesis.
Mechanism:
• GH → ↑ IGF-1 → osteoblast proliferation.
• Enhances calcium retention.
Dosage:
• 2-4 IU/day (for bone-specific benefits).
• IGF-1 LR3 (20-50 mcg/day) can be used alternatively.
Note: GH works best with adequate protein and resistance training.
---
6. Nutrition - The Foundation of Bone Growth
A. High Protein (mTOR Stimulation)
Mechanism: Leucine activates mTOR, increasing osteoblast activity.
Dosage: 1.6-2.2 g/kg bodyweight (prioritize whey, collagen, and bone broth).
B. Optimized Carbohydrate Intake (Insulin-Mediated Bone Formation)
Mechanism:
• Insulin is an anabolic hormone that enhances osteoblast activity and collagen synthesis.
• Carbohydrates post-workout spike insulin, improving nutrient delivery to bones.
Dosage: 3-5 g/kg bodyweight (adjust based on activity level).
Prioritize peri-workout carbs (e.g., dextrose, rice, oats) for maximal insulin sensitivity.
C. Vitamin D3 + K2 (Osteocalcin Activation)
D3 (5000-10,000 IU/day) → calcium absorption.
K2 (MK-4/MK-7) → activates osteocalcin, directing calcium into bones.
D. Magnesium, Zinc, Boron
Magnesium (400-600 mg/day) → cofactor for bone enzymes.
Zinc (30-50 mg/day) → collagen synthesis.
Boron (3-10 mg/day) → reduces calcium excretion.
E. Collagen & Hyaluronic Acid
Type II collagen (10-20 g/day) supports bone matrix formation.
---
7. Additional Considerations
A. Mechanical Loading (Weight-Bearing Exercise)
Resistance training and impact exercises (jumping) stimulate bone remodeling.
B. Progesterone (Potential Synergy)
Low-dose progesterone may enhance osteoblast activity (needs more research).
C. Pentoxifylline (TNF-α Inhibition)
Reduces bone resorption by suppressing inflammatory cytokines.
---
Bone Growth Stack
Vorinostat 50mg per day
Anavar - 50mg per day
Testosterone - only use if you can maintain low estradiol with an AI
Teriparatide - 20mcg per day
GH 5iu per day
Letrozole 0.5mg every other day
Vitamin K2 MK4 - 100mg per day (consumed with 10g+ fat)
Vitamin D3 - 10K IU per day (consumed with 10g + fat)
Protein 0.8g/lb bodyweight
Carbohydrates - 3-4g/lb bodyweight
---
Conclusion
The optimal bone growth stack combines pharmaceutical agents (HDAC inhibitors, PTH, steroids, GH) with targeted nutrition (high protein, strategic carbohydrate intake, D3/K2, collagen). Anavar and teriparatide are particularly potent, while vorinostat offers a novel epigenetic approach. Carbohydrate timing around workouts maximizes insulin's anabolic effects on bone, while protein and micronutrients provide the building blocks for osteogenesis. Aromatase inhibitors can delay ephiphyseal plate closure which means a longer time for these compounds to exert their effects.
For best results, pair this stack with progressive resistance training, adequate recovery, and periodic blood work to monitor biomarkers like IGF-1, estrogen, and calcium levels.
TGF-B's Role in Bone Growth
1. Mechanisms of Action
TGF-B signaling influences bone development through:
Stimulation of Mesenchymal Stem Cells (MSCs) → Drives osteoblast and chondrocyte differentiation.
Enhancement of Extracellular Matrix (ECM) Deposition → Boosts collagen, osteocalcin, and alkaline phosphatase activity.
Modulation of Growth Plate Chondrocytes → Supports longitudinal bone growth before epiphyseal closure.
---
2. TGF-B vs. BMP Signaling
While BMPs primarily drive osteoblast differentiation, TGF-B has a broader regulatory role:
Early-stage osteogenesis (MSC recruitment)
Bone remodeling (coupling osteoblast-osteoclast activity)
Chondrocyte maintenance (critical for growth plate function)
---
