PepAssess matches each report to the issuing lab's own public record, not the vendor's copy.

How can I tell if a Tirzepatide 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 Tirzepatide report it finds: as of November 12, 2026, 32 of the 34 sellers publishing a Tirzepatide report had one the lab confirmed.

How much does a vial of Tirzepatide cost?

As of November 12, 2026, a 30 mg vial of Tirzepatide costs a median $125 across the 21 sellers PepAssess found with one in stock (lowest $72); a 10 mg vial, a median $59.99 across 19 sellers (lowest $24); a 60 mg vial, a median $188 across 17 sellers (lowest $105). 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.

Yes. As of November 12, 2026, 86 of the 48 Tirzepatide sellers PepAssess lists sell a vial; 2 a pen or pre-filled form and 1 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 Tirzepatide sold under?

Many shops sell Tirzepatide under a code name. PepAssess files 19 of them under Tirzepatide, from 30 sellers' own product names: GLP-2 TZ (9 sellers), GLP-2T (5 sellers), GLP-2 TRZ (Everest Peptides), H-(T) (Hydro Research Peptides), RO-2TZ (Retaone Labs), RIVN-2TRZ (Rivn Research), RIVN-2TZ (Rivn Research), LCA-T2 (Lost Coast Aminos), SLP-2 (Silverstone Labs Co), VA-T2 (My Amino Lab), RXL-2TRZ (RemedyX), PG-2TZ (Peptide Giants) and 7 more. Each seller's prices, lab reports and coupon code are on this page.

How do I know if a Tirzepatide seller is legit?

Check what the seller can show. As of November 12, 2026, PepAssess checks every Tirzepatide seller for three things: a Tirzepatide lab report that the testing lab confirms on its own records (32 of 48), card payments, which let you dispute a charge (39 of 48), and a published street address — not a mailbox or registered agent (18 of 48). Each seller's PepAssess profile shows which of these it has.

Are there Tirzepatide coupon codes?

Yes. PepAssess lists coupon codes for 48 vendors selling Tirzepatide: Hydro Research Peptides: PepAssess20 (20% off), Lost Coast Aminos: PEPASSESS (10% off), Bench Grade Peptides: PEPASSESS (10% off), Next Level Compounds: pepassess (30% off), GigaCompounds: GC-PEPASSTFAAD (10% off), Retaone Labs: PEPASSESS (5% off) and 42 more.
