Paradigm Peptides

Read audit →

We could not verify a named third-party lab or current batch COAs, and public reviews include complaint reports alleging mislabeled products and order problems. On that basis — unverified testing plus unresolved complaints — we don't recommend buying. Treat these scores as low-confidence.

Strengths

    • No named third-party lab or verifiable current batch COA
    • Public complaint reports allege mislabeled products
    • Reported order / fulfillment problems
    • We can't confirm active, tested supply

    How we rank

    One formula, the same for every vendor including our partner. Argue with the weights — that's the point.

    Transparency40%
    Purity30%
    Shipping15%
    Value15%

    Overall = 0.40 × Transparency + 0.30 × Purity + 0.15 × Shipping + 0.15 × Value

    Paradigm Peptides: 0.40×2 + 0.30×3 + 0.15×3 + 0.15×3 = 2.6

    How each axis is scored

    Transparency (×0.4). COA depth, named third-party labs, breadth of test types (HPLC base; +MS, +LAL, +heavy metals, +sterility), public batch traceability. Claim-only purity (no hosted PDF) caps this axis.

    Purity (×0.3). Median/recent batch purity from hosted COAs + independent lab confirmation (Finnrick/Janoshik). Self-reported '99%+' with no batch PDFs scores low.

    Shipping (×0.15). US-domestic speed/reliability and stock consistency from real shipping data; international-only or undisclosed scores lower.

    Value (×0.15). Purity-adjusted price per mg vs the cross-vendor median for the same peptide/vial; discount-dependency penalized.

    Reviews

    No first-party verified-purchase reviews yet — we don't publish star aggregates we can't verify. Third-party reputation (e.g. Trustpilot), where it exists, is weighed in the audit above and the Transparency score for Paradigm Peptides.

    Why trust this comparison

    • Every vendor is scored from real evidence on four public, weighted axes — before we know any margins.
    • Purity claims are cross-checked against named third-party labs (MZ Biolabs, Finnrick, Janoshik). Claim-only purity is marked as such.
    • The scoring code can't read which vendor pays us — the editorial-commerce firewall is enforced in software.
    • We disclose the 20% / 10% Alpha Pro commission on every page, above the first link.

    Vendors out-rank our own partner: Peptide Partners (9.0) and Protide Health (8.9) and Ascension Peptides (8.8) both score above Alpha Pro (8.6). We left it that way.
