What we found at MyPurePeptide
Read 30 September 2026 on the vendor's own pages
MyPurePeptide is the first vendor since Purgo to clear all ten checks on a first read: a Janoshik report we opened at the lab, a batch on every record, measured content, an open directory, a named LLC with a phone and a card rail. The address is a mailbox, the BPC-157 lot runs 116% of label, and the GLP-class pages lean on inflated 'was' prices — all disclosed above. 10/10 on the rubric; read the flags before treating it as Purgo's equal on price honesty.

Could not verify · flags
?Premises — the printed address is a commercial mailbox (PMB) in an Austin office building, so it identifies the company, not where the vials are.
?That the report matches the vial you receive — the vendor's own homepage says a report 'alone does not confirm the lot shipped'; check the batch on your label against the directory.
!The BPC-157 report measures 11.61mg on a 10mg label — 116%, just over our 115% flag line; TB-500 measured 11.54mg (115%).
!GLP-class product pages print strike-through reference prices far above the selling price (Semaglutide 10mg 'was $399.99' now $70; Retatrutide 10mg 'was $699.99' now $80; Tirzepatide 60mg 'was $499.99' now $90). The 'you save' figures are marketing, not a discount you would otherwise have paid.
!Catalog includes semaglutide, tirzepatide, retatrutide, cagrilintide and mazdutide sold as research materials.
!Returns: 7-day unopened window; damage or shortage claims need a continuous unboxing video within 48 hours of delivery.
!A lookalike domain, mypurepeptides.com, is disclaimed on the vendor's homepage as not theirs.

Where MyPurePeptide ranks by compound
MyPurePeptide appears in 7 of our compound rankings, top-3 in 7. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-3010/10 — first assessment (rubric v2); all ten awarded — Janoshik report opened at the lab, batch on every record, named LLC (PMB address, disclosed), Visa/Amex rail. Flags: 116% of label on BPC-157; strike-through reference prices on GLP-class pages
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
MyPurePeptide: the caveat
The printed address (12407 N Mopac Expy Ste 250 PMB 570, Austin) is a commercial mailbox, not premises — identity is awarded on the named LLC with that disclosure. The BPC-157 report measures 11.61mg on a 10mg label, 116% — just over our 115% flag line; TB-500 10mg measured 11.54mg. The vendor's own site says a report 'alone does not confirm the lot shipped'. The GLP-class pages print strike-through reference prices far above the selling price (Semaglutide 10mg 'was $399.99', now $70; Retatrutide 10mg 'was $699.99', now $80) — treat the 'you save' figures as marketing. Zelle is offered alongside cards. Returns: 7-day unopened window with a continuous unboxing video required for damage claims. A domain lookalike (mypurepeptides.com) is disclaimed on the vendor's homepage.

Is MyPurePeptide legit?
