Excellent
Sells retatrutide under the code name "GC-RT" in 10mg, 20mg and 30mg vials, shipped FedEx 2-Day from Richmond, Virginia. Janoshik reports name the compound retatrutide; the latest (30mg batch) was analyzed August 13, 2026.
Worth knowing (not scored)
- Retatrutide identity: product name 'GC-RT' only; all three Janoshik reports (client gigacompounds.com) list 'Retatrutide' in results from a GLP-1 blind identity test.
- Janoshik verification pages (janoshik.com/tests and /verify) returned HTTP 403 / Cloudflare block, so reports could not be confirmed with the lab.
- Site summaries for GC-RT-10-02 and GC-RT-30-02 show averages matching the Janoshik values (2 and 3 vials on the reports), though the site lists '5 Vials Tested' for the 30mg batch. Earlier batches GC-RT-10-01 (May 14, 2026) and GC-RT-30-01 (March 9, 2026) are marked depleted; lab-tests page also lists GC-RT 15mg and 50mg batches not currently sold.
- Pre-order bundles (10 vials, shipped in 8-12 weeks) are offered; pre-order payments are Zelle, bank transfer or crypto only.
- WhatsApp contact offered alongside email; ordering is through the site's own cart, which prompts for a research account.
- Catalog also includes IGF-1 LR3, kisspeptin, PT-141 and tirzepatide ('GC-TRZ'); no steroids, SARMs, HGH, HCG or testosterone found.

Lab details are as published by the vendor. We have not yet matched these reports on the lab’s own verification page; the lab’s site blocks automated checks, so this is done by hand.
