For example: A 40 mg label indicates the total mass of the peptide compound It does not specify concentration after dilution It does not define frequency, timing, or method of use This convention is consistent across many investigational peptides and research compounds

GHK-Cu (copper peptides) GHK-Cu special considerations: Contains copper = oxidation concern More sensitive than most peptides Color changes indicate degradation Shelf life: Lyophilized frozen: 1-2 years (shorter than most) Lyophilized refrigerated: 6-12 months Reconstituted: 21-28 days (some say 21 days safer) Color monitoring: Fresh GHK-Cu: Light blue or clear with blue tint Acceptable: Maintained blue color Degrading: Deepening blue or turning brown/green Bad: Brown, green, or black = severely degraded Storage best practices: Freeze powder (very important for GHK-Cu) Protect from light religiously (amber vials ideal) Reconstitute smaller amounts (2-3 weeks vs 4 weeks) Monitor color weekly Discard if color darkens significantly See our GHK-Cu 50mg copper peptide dosage , copper peptides GHK-Cu guide , and should copper peptides be refrigerated
Retatrutide does not yet have an approved label defining indications, dosing, contraindications, warnings, or monitoring
Side effects of MK-677 include pronounced appetite increase, more significant water retention than ipamorelin, and notable effects on blood sugar and insulin sensitivity
