Peptides AcademyGHK-Cu + CJC-1295/Ipamorelin + Collagen Peptides Skin Stack
A multi-level skin rejuvenation protocol combining topical signaling (GHK-Cu), systemic GH-axis elevation for fibroblast activation and collagen gene expression, and oral collagen peptides for substrate provision. This stack targets skin aging from three complementary angles: local signal, systemic hormonal milieu, and building material supply.

How to Use Together
Morning: Topical GHK-Cu serum (1–2%) applied to clean face/neck/décolletage → moisturizer → SPF 30+. Any time: Oral hydrolyzed collagen peptides 10–15 g dissolved in liquid (+ 50 mg vitamin C if dietary intake is low). Bedtime: CJC-1295 (no DAC) 100 mcg + Ipamorelin 100–200 mcg subcutaneous on empty stomach (2+ hours post-dinner). The GH elevation during sleep amplifies the natural nocturnal repair window when collagen synthesis peaks. Cycle: GH peptides 8–16 weeks on, 4–8 weeks off. GHK-Cu topical and collagen peptides continuous.
Safety Notes
GHK-Cu topical is extremely well-tolerated; patch test on inner forearm if you have reactive skin. Oral collagen has no known side effects at standard doses. GH-axis peptides require IGF-1 monitoring — target upper-normal range for age. Excessive GH elevation can worsen insulin sensitivity and cause water retention. Discontinue GH peptides if IGF-1 exceeds age-appropriate upper limit. Sun protection is mandatory — UV-induced MMP activation degrades collagen faster than any peptide can rebuild it.

CJC-1295 + Ipamorelin
Research-Grade
The most widely used GHRH + GHRP stack — CJC-1295 extends GHRH half-life while Ipamorelin selectively amplifies GH pulses without disturbing cortisol or prolactin.
Hydrolyzed Collagen Peptides
Various (Supplement)
Enzymatically hydrolyzed collagen broken into short peptides that survive digestion — marketed for skin, joint, and connective-tissue support.
GHK-Cu (Copper Tripeptide-1)
Cosmetic-Grade
A naturally occurring copper-binding tripeptide (Gly-His-Lys) with decades of cosmetic dermatology research in wound healing and skin remodeling.
Ipamorelin
Research-Grade
The most selective GHRP (growth-hormone-releasing peptide) — amplifies GH pulses via ghrelin/GHSR receptor without meaningful cortisol, prolactin, or aldosterone crosstalk.
