1 buyer says a $300 order for 2 items never arrived and support went unanswered.

Lonza Factory Store sells research peptides at lonzafactoryvip.shop.

Where it trips our checks

• Non-delivery: A Reddit buyer report says 2 items never arrived after payment. A paid order with no delivery is a pattern we see repeatedly in bad actors.
• Blocked or ignored: That buyer says support did not answer repeated messages.
• COA traceability: The COA directory has purity claims and spectra, but no visible batch link, lab identity, or report date.
• Contact transparency: The site gives a domain email and GMT+8 hours, but no legal entity or physical address.

Sources

• The Reddit thread contains the loss report and delivery-positive anecdotes.
• The seller's site, COA page, and contact page.
• A logged-in Reddit sweep covered the domain, reported alias, and Lonza Factory; glp1forum returned no matches.

Bottom line: 1 detailed loss report creates documented risk. More independent order records would change the picture.
