- Thymalin
- Thymic peptide restoration
- Immune T-cell maturation, autoimmune regulation
- 10mg subcutaneous every 3–5 days, 10-injection cycle
- 10–14 days for immune marker changes
- Best option for perimenopause research focused on immune dysregulation and autoimmune flare prevention during estrogen withdrawal
- GHRP-6
- Growth hormone secretagogue (ghrelin receptor agonist)
- Pituitary GH release, lipolysis, osteoblast stimulation
- 100–200mcg subcutaneous 2–3× daily
- 4–8 weeks for metabolic and body composition shifts
- Strongest evidence for metabolic preservation and bone density support; requires multiple daily injections
- MK 677 (Ibutamoren)
- Orally bioavailable ghrelin mimetic
- Sustained GH/IGF-1 elevation over 24 hours
- 12.5–25mg oral once daily
- 6–12 weeks for lean mass and bone density improvements
- Most practical for sustained GH support; oral administration simplifies compliance in long-term research protocols
- Epithalon
- Telomerase activator
- Telomere length preservation, reduced cellular senescence
- 10mg subcutaneous daily for 10 days, cycled every 3–6 months
- 2–4 weeks for cellular aging biomarker changes
- Addresses upstream aging mechanism accelerated by estrogen withdrawal; limited human trial data but strong mechanistic rationale
- CJC-1295 + Ipamorelin
- GHRH analogue + selective GH secretagogue
- Amplified and sustained GH pulse when combined
- 100–200mcg each, subcutaneous 1–2× daily
- 3–6 weeks for noticeable metabolic and sleep quality improvements
- Best synergistic option for GH restoration; more complex dosing than MK 677 but avoids potential appetite increase
