Why researchers source retatrutide from PX1
Single vial retail access. Most suppliers gate metabolic peptides behind bulk minimums or wholesale approval. PX1 supplies retatrutide at true retail quantities: one 5 mg or 10 mg vial, no MOQ, no account application, no distributor paperwork.
Batch-matched analytical documentation. Each lot ships with a downloadable certificate of analysis containing the HPLC chromatogram (>99% purity), LC-MS or MALDI-TOF identity confirmation, LAL endotoxin results, and Karl Fischer moisture. Lot numbers on the vial match the published COA.
Vacuum-sealed lyophilized stability. Retatrutide is lyophilized to a white, uniform cake and vacuum-sealed under inert headspace, remaining stable in transit and for 18–24 months sealed. Store lyophilized vials at -20°C; reconstituted solution at 2°C–8°C for up to 30 days.
Express 1–2 day domestic delivery. Orders placed by 2 PM EST dispatch the same business day from our United States facility with tracked express service.
