REFERRAL OFFER
15% off with disclosed code
Code BENCHMARK takes 15% off at checkout, including during sitewide promotions; our referral link carries the attribution, so click through from here before you shop. The pricing board applies the 15% to regular listed prices only — it is not stacked onto the vendor’s one-vial sale or 10-vial quantity discount, which are separate storefront offers. Vendor-confirmed September 29, 2026.
PeptideBenchmark has a disclosed affiliate relationship with Peptide Maxxing. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.

Peptide Maxxing sells research-only singles and blends with prices and milligram strengths listed on the public catalog, including house labels RT Series, TZ Series, SM Series, and CAG Series for retatrutide, tirzepatide, semaglutide, and cagrilintide. The public /coa page and matching product certificates publish Freedom Diagnostics purity/content images, Janoshik endotoxin reports, and ILS Laboratories HPLC certificates; PeptideBenchmark confirms those Freedom Diagnostics search codes, exact Janoshik verification URLs, and ILS portal routes where lookup succeeds. Distinct from Peptide Tech and Peptide Partners.
Readers who want an openly priced U.S. research catalog with clear house-label mappings and centralized certificates that can be checked at Freedom Diagnostics, Janoshik, and ILS Laboratories.
RT / TZ / SM / CAG Series are branded storefront labels for retatrutide / tirzepatide / semaglutide / cagrilintide. HMG 75 IU appears in IU hormones and is not mixed into vial $/mg; pre-filled unit packs, aqueous solutions, and reconstitution supplies remain outside current supported comparisons. MITO30 is a dated mitochondrial-category overlay, not a standing ranking discount. Certificate coverage is not universal across every SKU — Gonadorelin, Pinealon, and SM + CAG currently have no published test result, and the Freedom image for RT Series 30 mg still has no laboratory-hosted PDF.
The vendor states U.S.-manufactured/finished positioning, support at [email protected] and +1 (561) 800-8146; no street-level public address verified.
Checked September 18, 2026Public COA page with Janoshik, Freedom Diagnostics, and ILS provider verification
The /coa page and matching product certificates publish Freedom Diagnostics purity/content images, Janoshik endotoxin reports, and ILS Laboratories HPLC certificates. PeptideBenchmark independently confirms Freedom Diagnostics search codes under Peptide Maxxing, exact Janoshik verification URLs, and ILS Access Code / QR portal routes, then re-checks them on the normal trust cadence. A matched certificate documents the tested sample and does not endorse every vial.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
