Example protocols with 100mg Skin rejuvenation protocol: Goal: Improved skin texture, reduced fine lines, enhanced collagen Dose: 2mg subcutaneously, 5 days/week Duration: 10 weeks Total peptide: 100mg exactly Reconstitution: Full vial at start, use within 30 days for first 60mg, freeze remainder in sterile vial, thaw at day 28 Recovery: 6 weeks off before considering second cycle Intensive hair support protocol: Goal: Hair follicle stimulation, reduced shedding, improved density Dose: 2mg daily, 7 days/week Duration: 7 weeks (one vial), then reassess Total peptide: 98mg (leaves tiny remainder) Reconstitution: Full vial, use 60mg in first 30 days, frozen portion for remaining 38mg Recovery: 4-8 weeks off, then evaluate need for second vial Conservative longevity protocol: Goal: General anti-aging, skin health maintenance, systemic benefits Dose: 1mg daily, 5 days/week Duration: 20 weeks (two 10-week blocks with reconstitution in between) Total peptide: 100mg Reconstitution: 50mg initially, frozen 50mg for second batch Recovery: 8-12 weeks off annually The getting started guide covers fundamentals for those new to peptide research

GHK-Cu is not yet approved for human consumption
These two Eli Lilly candidates act on completely different biology: retatrutide stacks three incretin and glucagon signals into one molecule, while eloralintide narrows the target down to a single satiety pathway the amylin receptor
This step is important because the copper stabilizes the peptide and contributes to biological activities attributed to copper peptides
126, no
The 2026 changes moved several peptides toward compounding eligibility (Category 1), not full drug approval
