Independent buyers testing LP Peptide vials post results all over the map: one retatrutide came back 99.8% pure, another lab flagged a reta vial as tirzepatide, and a ten-vial order included fillers.

LP Peptide (lppeptide.com), a China-based catalog vendor shipping research peptides to the US over WhatsApp and Telegram.

Where it trips our checks

• Substantiated reports: buyers report a mots-c that tested as filler and a reta15 a lab identified as tirzepatide, though none posted the certificates. Test results that swing this wildly from one seller is a pattern we see repeatedly in bad actors.
• Batch testing: other buyers show clean independent results, including a 99.8% reta and a 14-product group test, so quality reads inconsistent rather than uniformly bad.
• Domain and identity pattern: buyers report LP now trading as "HT," a "Yuan Peptides" merger, and scammers reusing LP's details.
• COA traceability: COAs are referenced constantly but almost never shared, and one buyer's own certificate showed less product than the label.

Sources

• The r/Biohacking "Has anyone order of lppeptides" thread (147 comments): mixed first-hand tests, one non-delivery heading to chargeback, one refund honored.
• The seller's own surfaces: lppeptide.com, a WhatsApp/Telegram order channel, and a seller-run r/LPpeptide_Laboratory.
• Cross-check: a glp1forum.com search returned no results.

Bottom line: use caution, mixed evidence across 8 checks. A publicly posted failing COA tied to a batch would move this to high risk.
