Lumira was Peptaura's highest-rated seller by review count until a 2026 incident. The evidence (an independent ILS Labs test plus community and X discussion) points to a Reta30 they sold not actually being retatrutide: purity and endotoxins were fine but the compound was reportedly wrong, and a user COA for a Reta batch shows no purity value at all. They're reported to be a rebrand of Welon. To their credit they refunded the buyer inside 24 hours through Peptaura and blamed prior management, and their products went unavailable on the platform after.
Score Breakdown
Lists 61 COAs on Peptaura, but these are supplier-provided; an independent ILS Labs test contradicted a product's identity, and a user COA showed a non-detect purity value.
COAs carry batch numbers/dates, but at least one Reta batch (WL-RT30-P00022) shows no purity value, and a sold product's identity was not caught by the supplier COA.
Batch numbers and dates present (e.g., WL-RT30-P00022, 2026-04), which did enable the issue to be traced.
Reported rebrand of Welon (which had a prior third-party D/Poor concern); the brand itself attributed the incident to 'previous management'.
Was the highest-rated Peptaura seller by volume (4.7, 278 reviews) but became the subject of public criticism on X and peptide forums after the incident.
Refunded an affected buyer within 24h via Peptaura; offset by separate reports of long delays and inconsistent tracking/support.
Evidence suggests a product sold as Retatrutide was not Retatrutide on independent testing, a serious labeling/identity concern.
Corroborated across an independent lab test, a forum thread, an X post, a user COA, and Peptaura's own availability status.
Positive Signals
- +Refunded an affected buyer within 24 hours via Peptaura's buyer-protection process
- +Batch-numbered COAs with batch dates (e.g., WL-RT30-P00022)
- +Was the highest-rated Peptaura seller by review volume (4.7, 278 reviews) before the incident
- +Publicly acknowledged the issue, attributing it to prior management
Trust Concerns
The core issue is identity: public information says a product sold as retatrutide didn't test as retatrutide at an independent lab, and a Reta batch COA shows nothing for purity. On top of that it's a reported rebrand (Welon) that already had a third-party knock. What cuts the other way is a fast refund through Peptaura's buyer protection and traceable batch numbers. This one is still moving, so I'd get any batch identity-tested independently before trusting it.
- !Evidence suggests a product sold as Retatrutide (Reta30) failed independent identity testing at ILS Labs (~May 2026): purity and endotoxins passed, but the compound was reportedly not retatrutide
- !A user-submitted COA for a Lumira Reta batch (WL-RT30-P00022, dated 2026-04) shows no purity value (non-detect)
- !Reported to be a rebrand of Welon, which has a prior third-party quality concern (Finnrick tentative D/Poor on Retatrutide 15mg)
- !Some buyers reported long shipping delays and inconsistent tracking/support
- !Products show as temporarily unavailable on Peptaura following the incident
Researcher Notes
- •Reported rebrand of Welon, which had a prior third-party D/Poor concern
- •Independent ILS Labs test reportedly found a 'Reta' product was not retatrutide (~May 2026)
- •A user COA for a Reta batch shows non-detect purity
- •Refunded within 24h via Peptaura buyer protection; now temporarily unavailable
- •Independent identity testing advised before relying on any batch
