If your opened vial has been at room temperature for more than 72 hours, refrigerate it immediately and watch the 28-day clock carefully
29 gauge, 1/2 inch: the standard for most peptide protocols, including BPC-157, CJC-1295/Ipamorelin, and GHK-Cu 27 gauge, 1/2 inch: acceptable alternative, slightly wider bore makes drawing viscous solutions easier U-100, 1mL capacity: the correct syringe volume for most peptide doses, with clear graduations for accurate measurement Bacteriostatic Water vs Sterile Water: Why the Distinction Matters Lyophilized peptides (the powdered form dispensed by compounding pharmacies) require reconstitution before injection
