Bottom line
GigaCompounds has thorough testing and low prices. Its policies leave the buyer with the risk once an order ships, and it is less than a year old.
Products and pricing
The product is sold as “GC-RT”. The page does not name the compound, but the Janoshik reports on the product pages identify it as retatrutide. Prices: 10 mg $60 and 30 mg $120, both in stock with a buy-one-get-one-free offer. The 20 mg size ($90, with multi-vial tiers down to $54 per vial) was out of stock. A 10-vial pre-order bundle of 20 mg vials is listed at $300 with no COA yet.
Testing
Each batch page reports results from five vials tested by Janoshik:
- 10 mg lot GC-RT-10-02: average 99.45%, 10.69 mg, endotoxin 1.875 EU/vial, TAMC/TYMC pass (analyzed July 2, 2026)
- 10 mg lot GC-RT-10-01: 99.59%, 11.28 mg (May 14, 2026)
- 20 mg lot GC-RT-20-01: 99.88%, 22.78 mg (June 2, 2026)
- 30 mg lot GC-RT-30-02: average 99.75%, 35.35 mg, endotoxin 2.988 EU/vial (July 28, 2026)
Janoshik verification keys are included. An earlier 30 mg lot (March 2026) was tested by Kovera Labs. That report’s identity line reads retatrutide, but its listed molecular formula does not match retatrutide’s. The company says it keeps failed batches listed.
Shipping and payment
All orders go FedEx 2-Day from a facility in Virginia to all 50 states and DC. Orders are processed within 1 business day, and orders placed by 2 pm ET usually ship the same day. Shipping is free over $200; we did not find the rate for smaller orders. We found no list of payment methods. The site gives 3% cashback in store credit on delivered orders.
Policies and support
All sales are final. Damaged, defective or incorrect items must be reported within 48 hours with photos. Any fix is at the company’s discretion, and payment processing fees are deducted. The company does not cover lost, stolen or misdelivered packages; buyers must claim with FedEx. Support is by email (reply within 1 business day) and WhatsApp (2–3 hours), Monday–Friday 9 am–5 pm ET. The terms name GigaCompounds LLC. No phone number or street address was published.
Reputation
The domain was registered January 24, 2026. Trustpilot shows 4.8 from 58 reviews (98% five-star) on a profile claimed in March 2026. The few complaints mention broken or missing vials, which reviewers say were replaced. We found no FDA warning letter or Eli Lilly lawsuit naming the company.
