Bottom line
HelixCore Biotech has well-written policies, good prices and a Janoshik report that confirms retatrutide. It is also a new store with no independent reviews.
Products and pricing
“GLP-3 RT” is listed as “a synthetic research-use peptide”. The product page does not name the compound or describe its receptors. Current prices: 10 mg $70, 15 mg $89.99, 30 mg $154 (about $5.13/mg). Orders of 3 or more vials get 5% off and 6 or more get 10% off. The page showed the product in stock.
Testing
The 10 mg COA is a Janoshik report (task #150000) on batch 2026041210, which matches the lot the product page says buyers will receive. It ran a blind GLP-1 test that identified retatrutide at 11.16 mg and 11.10 mg, with purity of 99.266% and 99.337%. The report lists the client and manufacturer only as “G”. The COA library also lists a 15 mg lot at 99.8% and a 30 mg lot at 99.9%, both released April 23, 2026. We did not see endotoxin testing.
Shipping and payment
Orders ship from a US facility within 1 business day, via USPS Priority or UPS Ground with tracking. Standard shipping (3–5 business days) costs $8.50, or is free on orders of $150 or more. Priority (1–2 business days) costs $12.50. Packaging is plain. Payment by card, crypto, Zelle and Venmo.
Policies and support
All sales are final, with no returns. Every order includes free shipment protection, which reships packages lost in transit (14 days after shipping), held at customs, damaged or wrong. Claims are due within 14 days of the expected delivery date. Refunds are given only when a reship isn’t possible. Support is by email, Monday–Friday 9 am–5 pm ET, with replies within one business day. The site lists HelixCore LLC, 306 W Redwood St STE 201, Baltimore, MD 21201, and (240) 359-1022, but says the phone is for vendor and compliance matters only.
Reputation
helixcore.us was registered June 16, 2026. The support email domain, helixcorebio.store, was registered May 8, 2026 and now redirects to helixcore.us. Neither domain has a Trustpilot profile. The only reviews are two on-site ones, dated March and April 2026, before either domain was registered. We found no FDA warning letter or Eli Lilly lawsuit naming HelixCore.
