Seller reviews

One page per seller: the score, key findings and every point with the page it came from. Snapshot 25 September 2026.

• Leolabs67Place 1 · leolabs.co.zaThe only seller with a large independent review profile, and one of three that publish retatrutide lab reports. The newest report is about 11.5 months old, prices are among the highest per mg, and the product page links a dosing guide.
• Pure Performance Labs59Place 2 · purelabs.co.zaPublishes the most recent retatrutide lab report of any seller, with a verification key. The report does not name a batch, and the product pages give human dosing and weight-loss claims.
• Molon Labs46Place 3 · molonlabtides.comLow prices and a published retatrutide lab report, but the report cannot be verified, and the "COA preview" boxes on product pages show lot results that no published document supports.
• Vitality Lab39Place 4 · vitalitylab.co.zaThe lowest price per mg among rated sellers and a large, all-positive Google review profile. No lab reports are published, and product pages carry dosing schedules despite a "not for human consumption" notice.
• ReGen-X31Place 5 · regenx.co.zaA registered company with card payment, but it says every batch is independently tested without publishing any test, and its blog links weight-loss injection content to the retatrutide product.
• TrueForm28Place 6 · tfpeptides.co.zaLow prices and full delivery terms, but no lab reports, downloadable dosing tables and strong weight-loss wording.
• Genesis Peptides26Place 7 · genesispeptides.co.zaFull delivery terms, but no lab reports, dosing given in mg and pen clicks, and an anonymous operator.
• Chrono Pharm24Place 8= · cronopharm.co.zaTemperature-controlled delivery and PayFast named, but a human injection dosing table on every retatrutide page and contradictory claims about lab reports.
• Lekker Peptides24Place 8= · lekkerpeptides.co.zaLow prices, but no lab reports, a dose-escalation table on most retatrutide pages, and a product named after a registered drug brand.
• BioHack Peptides23Place 10 · biohackpeptides.co.zaNo retatrutide lab report yet ("awaiting certificate of analysis"), a dosage calculator in the site header, and unfilled template terms.
• Peptera22Place 11 · peptera.co.zaNo dosing content and clear delivery terms, but retatrutide is sold under a code name, the mg amount appears only in product images, and several policies contradict each other.
• Peptides HQ21Place 12 · peptideshq.co.zaNo dosing content and a clear research-use disclaimer, but no lab reports, no policy pages, and hidden review markup with templated reviews.
• Peptide Labs20Place 13 · peptidelabs.co.zaA (Pty) Ltd with a research-use disclaimer, but full injection protocols up to 12 mg a week, products tagged "Ozempic", and testing claims with no published report.
• White Rabbit Labs19Place 14 · whiterabbitlabs.co.zaNine retatrutide listings under spaced-out names, injection guides in downloadable PDFs, and no published delivery terms.
• Apex Genetics18Place 15 · apexgen.co.zaStrong research-only wording on the site, but no lab reports, no policy pages, WhatsApp as the only contact, and packaging in the product image marked "For subcutaneous injection only".
• Bio Muti18Place 16 · biomuti.co.zaNames its founder and takes card payment, but its retatrutide page claims "SAHPRA Compliant", gives no mg amount and has no research-use disclaimer.
• Health & Fitness ZA18Place 17 · healthandfitnessza.co.zaA general fitness shop selling many retatrutide pens and vials with no research-use disclaimer, a full human dosing protocol and a product named "Mounjaro".
