The real Nantong Guangyuan (GYC) tells buyers its only site is ggpeps.com and that everything else is a scam. The requester was sent to ggpeps.net, which wears the same brand but shares none of the same channels.

ggpeps.net, a site presenting as Nantong Guangyuan Chemical (GYC), selling GLP-1 peptides and SARMs from claimed US, UK, EU and Australia warehouses.

Where it trips our checks

• Contact transparency: on glp1forum, GYC posts that its only official site is ggpeps.com with the email gbpeptides.com and warns all other channels are scams; ggpeps.net instead uses info@ggpeps.net and a support persona, "Gemma Conway." A lookalike domain reusing a known vendor's identity is a pattern we see repeatedly in bad actors.
• Domain and pressure pattern: a live countdown "Prosperity Sale," tiered discounts to 50% off, and a 10% crypto discount.
• Promotional signal: self-declared "Janoshik / PeptideMeter / GLP1Forum Verified" badges and a "TrustScore 4.9," none independently confirmed.
• Implausibly low pricing: retatrutide near 8 euros a vial, well under comparable offers.

Sources

• The reader who flagged the Telegram link to ggpeps.net.
• glp1forum's GYC posts naming ggpeps.com and gbpeptides.com as the only official channels and warning of impersonators; the site's own ggpeps.net pages.
• Cross-check: a logged-in Reddit sweep for "ggpeps" and "Nantong Guangyuan" returned no first-hand reports.

Bottom line: high scam risk. ggpeps.net is most likely a clone of GYC, not GYC. Whois showing a fresh domain, or GYC naming ggpeps.net directly, would confirm it.
