- GHK-Cu
- Copper-binding tripeptide activating collagen genes (COL1A1, COL3A1) + antioxidant enzyme upregulation
- Dermal thickening, wound healing, reduction of photoaging markers
- N/A (baseline compound)
- Daily (topical) or 2–3×/week (injectable)
- Essential structural remodeling component. One of few peptides with documented transcriptomic effects on tissue repair pathways
- BPC-157
- VEGF upregulation, nitric oxide modulation, gut-brain axis signaling
- Angiogenesis, tendon/ligament repair, gut integrity
- Complementary. GHK-Cu handles ECM synthesis while BPC-157 drives vascularization
- Daily during acute phases, 3×/week maintenance
- Best pairing for tissue repair stacks. Addresses blood supply bottleneck that limits collagen deposition efficacy
- Epitalon (Epithalon)
- Telomerase activation, pineal gland function restoration
- Cellular replication capacity, circadian rhythm optimization
- Non-overlapping. Epitalon targets DNA-level aging while GHK-Cu addresses extracellular matrix
- Cyclical (10–20 days on, 4–6 months off)
- Complementary but operates at different biological level. Combine for cellular + structural approach
- NAD+ Precursors (NMN/NR)
- NAD+ restoration for sirtuin activation and mitochondrial function
- Metabolic efficiency, DNA repair enzyme function
- Indirect synergy through improved cellular energy status
- Daily oral supplementation
- Enhances baseline cellular function but doesn't directly impact GHK-Cu's collagen signaling. Useful foundation
- Retinoids (Tretinoin)
- Retinoic acid receptor activation increasing cell turnover
- Epidermal renewal, reduction of fine lines, hyperpigmentation correction
- Potentially synergistic but irritation risk when layered. Dermatological protocols often alternate days
- Nightly (topical)
- Proven efficacy but mechanism overlap with GHK-Cu on collagen gene expression. May not justify stacking both topically
- Growth Hormone Secretagogues
- GH/IGF-1 axis stimulation
- Muscle preservation, lipolysis, overall anabolic signaling
- Complementary. GH supports systemic anabolism while GHK-Cu targets dermal structure
- Daily (MK-677 oral) or 5 days on/2 off (GHRP-2 injectable)
- Strong pairing for comprehensive body recomposition + skin quality. Non-redundant pathways
