Pros and cons
- CAS 2381089-83-2 shown for every retatrutide size
- ILS Laboratories COA for each lot, with heavy-metal and fentanyl screens and an online verification link
- Sale prices from $19 (5 mg) and $69 (30 mg)
- Trustpilot 4.8 from 61 reviews; phone and email support
- Shipping policy still has a template placeholder where the carrier names should be
- ILS checks identity by HPLC retention time, not mass spectrometry; no endotoxin result on the 10 mg report
- All sales final; risk of loss passes to the buyer at shipment
- Two different Wyoming addresses and no ship-from location
Bottom line
Premier Bio Labs combines low sale prices, a large catalog and a good Trustpilot record. Its testing is narrower than the best vendors’, and its policy pages look unfinished.
Products and pricing
The product is sold as “PBL-RT3” (also labeled “Triad”) and described as a “modified incretin receptor agonist” with CAS 2381089-83-2. Sale prices: 5 mg $19 (was $49.99), 10 mg $49 (was $73), 20 mg $89.99, 30 mg $69 (was $129.99) and 60 mg $173.99 (out of stock). During the sale, 30 mg cost less than 20 mg. Multi-packs and a mix-your-own 5- or 10-vial kit are also offered.
Testing
Each size links to a COA from ILS Laboratories (San Diego) with an online verification link. The 10 mg lot G3RT10-02 tested 99.89% by HPLC with 10.26 mg measured, analyzed June 16, 2026. Identity was confirmed by HPLC retention-time match, fentanyl was not detected, and heavy metals were below detection. The current lots for 5, 20, 30 and 60 mg are listed at 99.85–99.90%. The ILS report names the sample “PBL-R3”, and the site’s COA index labels it retatrutide. The 10 mg report includes no endotoxin result, although the site’s quality policy says endotoxin testing is done.
Shipping and payment
Product pages promise same-day shipping on in-stock orders. The shipping policy instead says orders are processed in 1–2 business days, and its carrier field still reads “[Insert Carrier(s)]”. Orders ship FOB origin, so risk passes to the buyer once the carrier has the package. We found no shipping rates or free-shipping threshold. The listed payment methods are Visa, Mastercard, American Express, USDT and Plaid e-debit, with wire or ACH for large orders.
Policies and support
All sales are final. Damaged, defective or tampered orders must be reported within 48 hours with photos. After review, the company sends a replacement or issues a refund. Wrong items are resent at no cost. Support is by phone at (307) 370-2330 and by email, Monday–Friday 9 am–5 pm. The contact page lists 1603 Capitol Ave Suite 413, Cheyenne, WY. The refund policy lists a mailing address at 30 N Gould St, Ste R, Sheridan, WY. The COA names the client as PremierBioLabs LLC.
Reputation
The domain was registered September 7, 2025. Trustpilot shows 4.8 from 61 reviews (95% five-star) on a profile claimed in October 2025. Visible complaints about damaged or missing vials say the company replaced them. Trustpilot notes that the company has not replied to negative reviews. We found no FDA warning letter or Eli Lilly lawsuit naming the company.
