• Testing transparency

  14/40

  Public 7-category testing rubric grade plus disclosed testing methods plus a named third-party lab. The full range is gated on the vendor publicly naming the tests they run; a high rubric grade without disclosure caps at 18 of 40.

• Operational & regulatory standing

  22/25

  Reflects FDA actions, payment-processor issues, ownership uncertainty, closures, and editorial audit notes the vendor-risk monitor has surfaced. A recent published COA earns a small bonus on top of the operational base.

• Operational stability

  12/15

  Vendor age. 5+ years of operation earns full points; 1 year or less earns minimal credit. Absent foundedYear earns a neutral default; absence of data is not proof of risk.

• Verification tier

  10/10

  Editorial tier assignment based on documentation completeness, response to corrections, and presence of verifiable business address. Tier 1 vendors meet the highest bar.

• Price discipline

  10/10

  Heuristic check on aggressive discounting. Reasonable codes (<=25%) earn full points; 25-40% earns half; >40% off list often signals inventory clearance or churn and earns zero.

Nexus Peptides operates a GLP-1-forward catalog covering Tesofensine alongside the standard Semaglutide and Tirzepatide staples. Founded in 2022, the storefront has four years of continuous trading and a clean regulatory standing as of May 2026. The C grade of 68 reflects an absent public testing-method disclosure rather than any active operational concern. The Trust Score is built from a 14-of-40 testing component (no disclosed methods, capped at 18 even with a 5.5 internal grade), a full 22-of-25 regulatory standing with no audit notes, and a 12-of-15 stability bonus that vendors three to four years old earn. The shortfall against the A-tier set is concentrated in testing transparency: a public HPLC method and a named laboratory would lift the testing component by 13 to 19 points. Buyers should confirm Tesofensine and other newer-compound SKUs ship with batch COAs from a research-grade pipeline; the GLP-1-forward catalog includes compounds with thinner testing infrastructure than the longer-established staples. Nexus Peptides is frequently cross-shopped against Apollo Peptide Sciences and Modern Research Peptides among readers prioritizing GLP-1 catalog depth. The 10% discount code (NEXUS10) is conservative by tier-1 standards.
