🧬 GHK-Cu — Skin & Regeneration Peptide
GHK-Cu (copper tripeptide) is a naturally occurring copper-binding peptide that has been studied for its role in collagen production, skin remodeling, wound repair, and cellular signaling.
Potential areas of interest include:
✨ Supporting collagen and elastin production
🧴 Improving skin firmness, texture and elasticity
🩹 Supporting skin repair and wound-healing pathways
🔥 Modulating inflammatory processes
💇 Supporting the hair follicle environment
🧬 Promoting extracellular-matrix remodeling
💪 Sermorelin — Natural Growth-Hormone Signaling
Sermorelin is a synthetic version of growth-hormone–releasing hormone (GHRH). Rather than supplying growth hormone directly, it signals the pituitary gland to release growth hormone.
Potential effects being investigated/used clinically include:
💪 Supporting lean muscle maintenance
🦴 Supporting bone health
😴 Potentially supporting sleep quality
🔥 Supporting normal metabolism and body composition
🧬 Supporting tissue repair and cellular processes associated with growth hormone
🔥 Ipamorelin — Growth-Hormone Secretagogue
Ipamorelin is a growth-hormone secretagogue. It acts on ghrelin receptors to stimulate growth-hormone release.
It has generated interest because it may stimulate GH with relatively selective activity compared with some older growth-hormone secretagogues.
Potential areas of interest include:
💪 Muscle recovery and lean-body support
🦴 Bone and connective-tissue health
💤 Sleep and recovery
🔥 Body-composition support
🧬 Growth-hormone–related tissue repair
🔥 Tesamorelin — Visceral-Fat–Targeted GH Pathway
Tesamorelin is different from the other peptides on this list because it is FDA-approved.
It is a growth-hormone–releasing-factor analog that stimulates the GH pathway and is specifically approved to reduce excess abdominal fat in adults with HIV-associated lipodystrophy.
Tesamorelin has attracted attention because studies have demonstrated reductions in visceral adipose tissue, the metabolically active fat surrounding internal organs.
Potential effects associated with its approved use include:
🔥 Reduction in visceral abdominal fat
📉 Changes in body composition
🧬 Effects mediated through growth-hormone/IGF-1 signaling
