Facts are what each site showed on 2026-09-21; a blank means not visible that day. Certificate publication is shown as information, not scored.

Vendors we would not order from, and why

Tier C is not an accusation. It is a list of facts read on the vendor's own pages that, on our grid, leave too little evidence of what is in the vial.

  • Peptira: Trustpilot profile removed (as displayed); Certificates not reachable without registration.
  • Simple Peptide: Catalog, prices and certificates behind registration; Trustpilot profile removed (as displayed).
  • Apex Peptides: Login wall: nothing verifiable; Trustpilot profile removed (as displayed).
  • Ion Peptide: Site not readable by automated check (Cloudflare block); facts below are Trustpilot only.
  • Modern Aminos: Site not readable by automated check; Trustpilot profile removed (as displayed).
  • PureRawz: Does not sell retatrutide; page carries weight-loss claims and affiliate links; Trustpilot profile removed (as displayed).

How we ranked

Every vendor gets the same grid, and the weighting is our editorial choice: the points go to what a buyer can verify before paying. A registration number identifies who is selling; a lot number on the vial ties the object in hand to a test record; tracked one-to-two-day shipping with a reship promise decides whether a lost parcel is the buyer's problem. Certificate publication is shown as information, not scored, because a certificate can be read only after the vial arrives.

  • 2 pts: Registered company with a registration number on the site
  • 2 pts: Lot number printed on every vial
  • 1 pt: Purity specification of at least 99% by HPLC and MS, per lot
  • 1 pt: Testing laboratory named
  • 2 pts: Tracked shipping in 1 to 2 days, lost parcels reshipped
  • 1 pt: Card payment with 3-D Secure
  • 1 pt: Ships to the United States and Europe
  • 1 pt: Plain research-use wording, no medical claims

Tiers follow the score: S is our pick, A the best-scoring alternative, B a vendor we would use with reservations, C a vendor we would not order from. Two or more red flags read on a site place it in C regardless of score. We do not take samples, do not run our own assays, and do not accept payment from any vendor for placement; the site is supported by the OXpeptides link, disclosed on the About page. Our pick scores 11 of 11.

Back to the doses

A vial is a container, not a dose. The weekly amounts that have human data, 1 to 12 mg, are laid out on the retatrutide dosage guide, and the arithmetic that connects a 10 mg vial to those figures is in the reconstitution guide.
