Retatrutide + Tirzepatide

Tirzepatide + Retatrutide is supplied by BioLifeLab as a lyophilized powder, sealed in a tamper-evident vial and stated at 99% purity on the label. It is supplied in a single 40 mg + 20 mg ampoule, so the size can be matched to how much material a study will consume before the vial is opened again. Store sealed vials between 2 and 8 °C in a cool, dry place away from direct sunlight; stability drops sharply once a peptide is reconstituted, so prepare only what a protocol needs. Supplied strictly for laboratory research use — not for human or veterinary use.
