Bottom line
Alpha Pro Peptides labels its retatrutide clearly and was running a steep promotion when we checked. Only one size was in stock, its policies are strict and it has no independent track record.
Products and pricing
The product is sold as “GLP-3”, with the label “GLP-3-R - Reta”, CAS 2381089-83-2, formula C221H342N46O68 and molecular weight 4731.3. Prices: 10 mg $74.99 (5% off for 3+, 10% off for 5+), 20 mg $119.99, 30 mg $169.99 and 50 mg $199.99. Only the 10 mg size was in stock. A “Buy 1 Get 1 Free Site Wide” banner brought the 10 mg vial to $37.49 each.
Testing
Each size has a Freedom Diagnostics COA reported May 18, 2026: 10 mg lot AP-RT10-0426 at 99.58% and 11.94 mg, 20 mg at 99.87% and 30 mg at 99.83%. The 50 mg page adds a Horizon Analytical report (lot AP-8032676, August 8, 2026) that names retatrutide at 99.5% and 49.92 mg. The 10 mg report shows no endotoxin result.
Shipping and payment
The shipping policy offers free shipping over $199, but product pages say $150. The FAQ says orders placed before 2 pm ET ship the same business day, with standard delivery in 3–5 business days and expedited shipping for a fee. The shipping policy instead gives 24–72 business hours of processing. Carriers are USPS, FedEx and UPS. Lost packages must be taken up with the carrier, and problems must be reported within 24 hours of the last tracking update. Payment is by major credit card except Mastercard.
Policies and support
No returns are accepted. Missing, incorrect or damaged items must be reported within 48 hours of delivery. Orders can be cancelled only before shipment. Support is by phone at (844) ALPHA-07, by email or by text. The terms are governed by Florida law, but the site gives no company name or address. The entry screen asks visitors to confirm they are an “authorized research partner”.
Reputation
The domain was registered February 20, 2026. There is no Trustpilot profile. Product pages display “4.7 · 1,000+ reviews” from on-site testimonials, which we could not verify. We found no FDA warning letter or Eli Lilly lawsuit naming the company.
