Updated version of the og peptide cheat sheet. Fixed KLOW (its GHK + BPC + TB + KPV, not what I said before), added nasal sprays, baked reconstitution into the tables, added frequency + bloodwork markers, and answered comments from last post. Few things new since Feb 2026: - FDA reclassified BPC-157, TB-500, CJC-1295, Ipamorelin + 10 others back to Category 1 - Retatrutide phase 3: 28.7% weight loss at 12mg (watch dysesthesia at 20%+) - CagriSema phase 3: 20.4% weight loss (NEJM June 2025) For research and educational purposes only. Not medical advice. Run bloodwork before any protocol.

Most people hear GHK-Cu and immediately think skin care… but it actually goes much deeper than that. GHK-Cu is a naturally occurring copper peptide that’s been researched for its role in tissue repair, regeneration, and healthy aging. While it’s well known for improving skin quality, it’s also being researched for wound healing, hair growth, inflammation, connective tissue support, and overall recovery. ✨ What it’s commonly researched for: 💙 Stimulating collagen & elastin production ✨ Improving skin tone, texture & elasticity 🩹 Supporting wound healing & tissue repair 💇‍♀️ Promoting healthier hair growth 🔥 Reducing inflammation & oxidative stress 💪 Supporting connective tissue recovery ⏳ Healthy aging & longevity One thing I found really interesting was a recent stability study showing GHK-Cu maintained over 99% purity after 3 months, whether it was stored at room temperature or refrigerated. Refrigeration had only a slight advantage (about a 0.125% difference in purity), making it one of the most stable peptides they’ve evaluated. 📚 Typical research protocols: Injectable (SubQ) • Typical dose: 1–2 mg, 2–3x per week • Common cycle: 8–12 weeks, followed by 2–4 weeks off Topical • Usually applied 1–2 times daily • Often used continuously for localized skin support. 💗 My experience: I’ve been using GHK-Cu with microneedling twice a month, and I’ve absolutely loved it. It’s become one of my favorite additions to my skin routine. 🛒 Atomik Labz GHK-Cu: https://atomiklabz.com/product/ghk-cu-100mg/ 🇺🇸 July 4th Sale: Use code CORI30 for 30% OFF non-BOGO items. 🎉 Any other time: Use code CORI15 to save 15%. 👇 Have you researched GHK-Cu yet?
