Administration technique Injection basics: Subcutaneous (under skin, not muscle) 29-31 gauge insulin syringe Inject slowly over 5-10 seconds Rotate sites (abdomen, thighs, arms) Reconstitution (if research peptide): Comes as lyophilized powder Reconstitute with bacteriostatic water Common: 2.4mg vial + 1ml water = 2.4mg/ml Refrigerate after mixing Use within 28-30 days Timing considerations: Can inject any time of day Many prefer evening (sleep through peak nausea) Consistency matters (same day weekly) With or without food (doesn't matter) See our peptide injections guide , how to reconstitute peptides , peptide storage guide , bacteriostatic water for peptides , water to mix with peptides , how long reconstituted peptides last in fridge , and lyophilized vs liquid peptides at SeekPeptides
