About Retatrutide
What it is
It is a single molecule that acts on the receptors for three gut and pancreatic hormones: GIP, GLP-1 and glucagon. Tirzepatide acts on the first two; retatrutide adds the glucagon receptor.
How it works
- Activates glucagon receptors, the feature that separates it from tirzepatide

Retatrutide: more questions people ask
Which Retatrutide vendors have lab reports confirmed by the testing lab?
48 as of November 12, 2026. Those whose confirmed reports cover both purity and toxicity: Hydro Research Peptides, Lost Coast Aminos, Bench Grade Peptides, GigaCompounds, Platinum Lion, Retaone Labs, Pinnacle Peptide Labs and PeakForce Labs and 21 more. PepAssess matches each report to the issuing lab's own public record, not the vendor's copy.
How can I tell if a Retatrutide certificate of analysis (COA) is real?
Look the report up in the testing lab's own records — most labs that test peptides publish a lookup by report ID, QR code or lot number. PepAssess does this for every Retatrutide report it finds: as of November 12, 2026, 48 of the 51 sellers publishing a Retatrutide report had one the lab confirmed.
How much does a vial of Retatrutide cost?
As of November 12, 2026, a 10 mg vial of Retatrutide costs a median $69.99 across the 30 sellers PepAssess found with one in stock (lowest $30); a 20 mg vial, a median $122.49 across 26 sellers (lowest $60); a 30 mg vial, a median $149.99 across 23 sellers (lowest $85). Each seller's lowest in-stock price for that size counts once; prices come from each seller's own store and exclude shipping and discounts.
Can you buy Retatrutide as a pen or capsules?
Yes. As of November 12, 2026, 100 of the 60 Retatrutide sellers PepAssess lists sell a vial; 4 a pen or pre-filled form and 2 capsules or another oral form. Counts come from each store's own product names. A lab report covers the product and batch it names — check that it's for the form you're buying.
What other names is Retatrutide sold under?
Many shops sell Retatrutide under a code name. PepAssess files 19 of them under Retatrutide, from 39 sellers' own product names: GLP-3 RT (17 sellers), GLP-3R (6 sellers), RT-3 (Prism Labs), H-(R) (Hydro Research Peptides), RO-3RT (Retaone Labs), RIVN-3RT (Rivn Research), OL-3R (Myoasis Labs), LCA-R3 (Lost Coast Aminos), SLP-3 (Silverstone Labs Co), VA-R3 (My Amino Lab), RXL-3RT (RemedyX), PG-3RT (Peptide Giants) and 7 more. Each seller's prices, lab reports and coupon code are on this page.
How do I know if a Retatrutide seller is legit?
Check what the seller can show. As of November 12, 2026, PepAssess checks every Retatrutide seller for three things: a Retatrutide lab report that the testing lab confirms on its own records (48 of 60), card payments, which let you dispute a charge (51 of 60), and a published street address — not a mailbox or registered agent (22 of 60). Each seller's PepAssess profile shows which of these it has.
Are there Retatrutide coupon codes?
Yes. PepAssess lists coupon codes for 60 vendors selling Retatrutide: Hydro Research Peptides: PepAssess20 (20% off), Lost Coast Aminos: PEPASSESS (10% off), Myoasis Labs: pepassess (20% off), Bench Grade Peptides: PEPASSESS (10% off), Next Level Compounds: pepassess (30% off), GigaCompounds: GC-PEPASSTFAAD (10% off) and 54 more.
