- Growth Hormone Secretagogue (MK 677)
- Stimulates pulsatile GH release via ghrelin receptor agonism
- 10–25mg daily (oral)
- 2–4 weeks for IGF-1 elevation; 8–12 weeks for dermal changes
- IGF-1 increase of 60–90% from baseline
- Foundational for systemic anabolic drive. Supports all downstream repair processes
- Thymic Peptide (Thymalin)
- Restores T-cell maturation; reduces systemic inflammation
- 5–10mg SC injection 2–3x/week for 10-day cycles
- 4–6 weeks for immune normalisation; 8–12 weeks for inflammation reduction
- CD4/CD8 ratio normalisation; IL-6 and TNF-alpha reduction
- Essential for controlling inflammatory collagen degradation. Allows GH effects to compound
- Collagen-Targeting Peptides
- Direct fibroblast stimulation; procollagen gene upregulation
- 5–15mg SC or topical high-penetration formulation
- 6–10 weeks for visible dermal thickness improvement
- Procollagen synthesis increase of 30–50% in vitro
- Most effective when combined with GH axis support. Substrate alone is insufficient without anabolic signalling
- Growth hormone secretagogues provide the systemic anabolic environment required for tissue repair. Thymic peptides remove the inflammatory brake that degrades newly synthesised collagen. Collagen peptides supply direct signalling and substrate. The combination creates conditions where net collagen deposition exceeds breakdown. The only pathway to measurable dermal improvement.
