Good

Sells retatrutide under the code name "GLP-3 RT" in 10mg, 15mg and 30mg vials and ships from the USA by USPS Priority or UPS Ground. Its posted Janoshik reports (April 2026) name retatrutide, but list the client and manufacturer only as "G", not HelixCore.

Worth knowing (not scored)

  • Retatrutide identity: site uses only 'GLP-3 RT'; the Janoshik reports (GLP-1 blind identity test) list 'Retatrutide' in the results.
  • All three Janoshik reports name the client and manufacturer as 'G' (not HelixCore), samples 'RT-10 (White cap)', 'RT-15 (Black cap)', 'RT-30 (Purple cap)', all ordered and received April 20, 2026 - before HelixCore LLC was organized (May 12, 2026). Batch numbers match the site's lot numbers. This may be a supplier's report; no clear evidence it is borrowed.
  • Measured mg and purity above are averages of the per-vial values on each report (10mg: 11.16/11.10 mg, 99.266/99.337%; 15mg: 16.49/16.38 mg, 99.809/99.860%; 30mg: 34.98/34.29/34.80 mg, 99.884/99.915/99.919%).
  • Janoshik verification pages returned a Cloudflare block, so the keys could not be checked.
  • Product pages show on-site customer reviews (e.g., 5.0 from 2 reviews on GLP-3 RT 10mg); no Trustpilot profile exists.
  • Support email uses a different domain (helixcorebio.store). Catalog includes HGH fragment 176-191, oxytocin and tesamorelin; no steroids, SARMs, full HGH, HCG or testosterone found.

Points in its favor

  • Maryland LLC named in Terms and found in state records via OpenCorporates
  • Ships from the USA within 1 business day with stated rates and tracking
  • Janoshik reports naming retatrutide for all three strengths
  • Card, crypto, Zelle and Venmo accepted

Points against

  • Lab reports list client 'G', not HelixCore, and predate the company's formation
  • Latest retatrutide reports are from April 2026
  • Business address is a registered-agent address; phone for vendor/compliance matters only
  • No Trustpilot profile
  • All sales final
