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?

Semax has been on my research list for a while, and it’s one I’m really excited to dive into. It’s a nootropic peptide that’s commonly researched for:🧠 Mental clarity 🎯 Focus & concentration 📚 Memory & learning ⚡ Brain fog 🛡️ Neuroprotection One thing that makes Semax unique is that it can be researched intranasally or by subcutaneous injection. The intranasal route is the most popular, but both options are available depending on your research goals. ➡️ Intranasal Air Dispersal Kit (ready to use): https://atomiklabz.com/product/semax-10mg-air-dispersal-kit/ ➡️ 10mg Injectable: https://atomiklabz.com/product/semax-10mg/ I also love that Semax is frequently paired with Selank since they complement each other really well: 🩷 Semax = focus, cognition & mental clarity 🧘‍♀️ Selank = calm, stress resilience & mood support Right now is a great time to pick it up because of the 🇺🇸 July 4th Sale! 🎆 30% OFF all non-BOGO items💥 Use code: CORI30 I’ll be starting my own research soon and, as always, I’ll be sharing my experience along the way. 👇 Have you researched Semax yet? If so, did you choose the intranasal route or injections, and what did you notice?

Pay attention to your health, and everything will be alright.

OK, your turn! This doesn’t have to be peptide-related at all. I want to hear your wins this week 👇 🏋️‍♀️ Did you hit a new PR? 🥗 Stayed consistent with nutrition? 🚶‍♀️ Finally hit your step goal? 😴 Prioritized sleep? 🧬 Started a new protocol? 💧 Drank your water? Let’s celebrate the little things because they add up. ❤️ Here’s my Friday Fit Check: 📍 January 2025: 143 lbs💗 Breast explant surgery that honestly kickstarted my health journey. 📍 February 2026: 130 lbs 🚶‍♀️ 10,000+ steps daily 🍽️ Small calorie deficit Nothing fancy… just consistency. 📍 March 2026: 🧬 Introduced Tirz and eventually switched to Retatrutide at 0.5mg and slowly titrated up to 1.5mg. 📍 Today: 120 lbs Current research: 🧬 Ipamorelin 150mcg 🧬 SS-31 4mg daily 🧬 KPV 250mcg daily 🧬 BPC-157 250mcg daily 🧬 Testosterone 🧬 B12 🧬 Tapering Retatrutide back down to 0.5mg while deciding whether a very low dose long-term makes sense for longevity benefits. Past lessons: 🧬 Tesamorelin was amazing at 250mcg… but increasing the dose gave me an instant 6–8 lbs of water retention, so my body quickly reminded me that more isn’t always better. 😅 Coming soon: ⚡ MOTS-C 3mg Monday/Wednesday/Friday starting in about 3 weeks 👀 Looking into 5-Amino as well. My ride-or-dies :📊 Renpho scanner (weekly trends > scale weight) 🚶‍♀️ 10–15k steps daily 🏋️‍♀️ Weight training 5x/week (obsessed with the WeRise app!) 🍗 120–130g protein daily 🍽️ Around 1,800 calories 💪 Creatine 💊 Daily supplements Current goals: ✨ Build muscle ✨ Improve body composition ✨ Get my ferritin up from a 9 after 2 months it’s now a 26 ✨ Continue focusing on longevity and feeling my absolute best. Your turn! Tell me one thing you’re proud of this week—big or small. I want to celebrate with you! 🎉❤️
