- The table below compares the primary peptide classes used in anti-aging protocols for men over 40, detailing mechanism, dosing, and professional assessment.
- Growth Hormone Secretagogues (CJC-1295 + Ipamorelin)
- GHRH and ghrelin receptor agonism. Increases pulsatile GH secretion without exogenous hormone
- 100–200mcg each, 3–4× weekly, subcutaneous injection before bed
- CJC: 6–8 days; Ipamorelin: 2 hours
- IGF-1 levels, sleep quality, lean mass retention
- Gold standard for restoring GH pulsatility. Most men see measurable IGF-1 increases within 4 weeks
- MK-677 (Ibutamoren)
- Oral ghrelin receptor agonist. Sustained GH and IGF-1 elevation
- 10–25mg daily, oral administration before bed
- 24 hours. Once daily dosing
- IGF-1, fasting glucose, appetite
- Convenient alternative to injectables but watch for glucose dysregulation in insulin-resistant men
- Thymalin
- Thymic peptide. Restores naïve T-cell production and immune surveillance
- 10mg daily for 5–10 days, subcutaneous or intramuscular, cycled every 3–6 months
- Short-acting. Effects cumulative over cycle
- CD4+/CD8+ T-cell counts, lymphocyte proliferation
- Essential for men prioritizing immune function. Clinical evidence strongest in immune senescence reversal
- Cerebrolysin
- Neurotrophic peptide mixture. Activates BDNF, NGF, CNTF pathways
- 5–10ml intramuscular, 10–20 session cycles
- Multi-day. Administered 2–3× weekly during cycle
- Cognitive testing scores, verbal fluency, memory recall
- Most robust neuroprotective evidence but requires IM administration. Not suitable for needle-averse users
- Dihexa
- HGF receptor agonist. Promotes synaptogenesis
- 2–5mg daily, oral
- 3–4 hours. Once daily
- Working memory, verbal fluency
- Potent synaptogenic mechanism but limited human data. Anecdotal reports positive
