   Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. pricing 7.6 to 5.5, operating history 2.5 to 2.7, transparency 3.5 to 6.5.

9. October 22, 2026Lowered from6.63→to6.42(-0.21)

   Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, site statements about testing that the certificates do not bear out and posted certificate copies that differ from the laboratory's own copy. Lab 6.9 to 6.5.

10. October 21, 2026Raised from5.87→to6.63(+0.76)

    Lab 5.5 to 6.9. The 18 October 2026 lab score averaged the whole catalogue of about 40 products, while every other vendor is scored over the products we list. Recomputed over the six products we list: three Freedom Diagnostics reports confirmed at the laboratory, two Freedom-named image certificates and one Janoshik report from 2025, with the same deductions for same-lot inconsistencies and the accreditation claim.

11. October 18, 2026Lowered from7.85→to5.87(-1.98)

    Re-audited 2026-10-18 against the July 2026 score. Lab 7.9 to 5.5: the catalogue has grown from about eight GLP-1 products to about 40, and only the seven February 2026 Freedom Diagnostics reports could be confirmed at the laboratory; the newer certificates are images with no code we could check, several show same-lot inconsistencies, and none covers endotoxin. Shipping 8.5 to 7.0: free shipping and card payment remain, but standard service is now FedEx 3-Day and nothing is refundable once shipped. Pricing 8.0 to 7.6: live prices sit at about the market median. Tenure 4.0 to 2.5: the domain dates from March 2025, and the July figure leaned on review volume. Transparency 8.0 to 3.5: the footer review rating comes from a site run by the vendor's own operators, the 'over 12 years' claim conflicts with the domain age, the address has changed, and a sister company in a UAE free zone is listed.
