Why Buy Retatrutide 15mg from Peptide Scientists

Every order ships from US-side fulfillment with 1-2 day handling, free shipping over $200, and a 30-day return guarantee. No prescription required for laboratory use.

Frequently Asked Questions

Is it safe to buy Retatrutide online?
Yes — research peptides are legal to purchase in the US for laboratory use. We source from Phiogen, which provides certificates of analysis and HPLC purity verification on every batch. Look for ≥98% purity and proper documentation when buying any peptide.
How much does Retatrutide cost compared to Ozempic?
Our 15mg Retatrutide vial costs $199.99 — covering 8 weeks of escalation dosing. Compare this to a single month of Ozempic at retail (~$1,000+ in the US without insurance). Research peptides offer a dramatic cost advantage.
What dose should I start with?
Standard protocol: 2mg/week for weeks 1-4, then 4mg/week weeks 5-8, then 8mg/week ongoing. The 15mg vial covers the first ~6 weeks at this rate. Always consult published Phase 2 dose-escalation data.
How fast will my order ship?
1-2 business day handling, then 2-5 day USPS/UPS transit within the US. Free shipping on orders over $200. Tracking provided at checkout.
