    Peptide Vendor Scorecard

    Every research compound vendor we track, scored on a transparent 0-100 scale. 5 weighted criteria, CSV-exportable, methodology published. No vendor can pay to move a score. Use this as the buyer-side risk-assessment framework Smartsheet templates can't be: peptide-specific, recalculated from current data, sourced from data the vendors themselves can audit.

    Risk Assessment Framework for Peptide Buyers

    Five risk categories every buyer should evaluate before paying any vendor, independent of trust score. Walk this top-to-bottom. If any single category fails, walk away regardless of price.

    Identity & Testing

    Critical risk

    Red flag: No COA, only self-issued tests, or COAs with no batch number / lot ID

    Check: Look for ISO-17025 third-party lab (Vanguard, Janoshik, Anresco, RIANI). Match lot/batch number on COA to the product page or vial label. If no lot, no buy.

    Payment Channel

    High risk

    Red flag: Crypto-only with no card option, untraceable wires, or 'message us for payment instructions'

    Check: At least one chargeback-reversible channel (Visa/MC, PayPal Goods&Services) means you have recourse if the vial never ships or arrives wrong.

    Shipping & Customs

    High risk

    Red flag: Vague shipping windows ("7-21 days"), no tracking, or no domestic origin listed

    Check: US-domestic USPS Priority is the gold standard for under-2-day, trackable, customs-free delivery. International with declared content gets seized regularly.

    Social Proof Authenticity

    Medium risk

    Red flag: Reviews only on their own site, all 5-star with no detail, or sub-100 lifetime reviews on a vendor claiming to be 'industry-leading'

    Check: Cross-reference on r/Peptides, Trustpilot (not bought), and BHG community reviews. Authentic reviewers mention specific lots, dose protocols, and side effects.

    Price Anomaly

    Medium risk

    Red flag: Prices >40% below market median for the same compound at the same vial size, especially on premium peptides (retatrutide, BPC-157, tirzepatide)

    Check: Cheap can mean efficient logistics, or it can mean diluted product. Pair price check with COA verification before assuming the low number is legitimate. See $/mg on each compound page at /compound/<slug>.

    Our Scoring Methodology

    Each vendor is evaluated against 5 criteria weighted by importance. COA verification carries the highest weight because third-party testing is the strongest indicator of product quality. Exact weights for every criterion are listed in the published rubric. Scores change as soon as new data is added.

    Not yet scored: cost-per-mg. We track prices, but per-milligram comparison needs a vial size on every listing and that coverage is currently uneven across vendors. Scoring it now would report a data gap as a price judgement, so it is excluded until coverage is complete rather than published half-measured. Per-mg prices are still shown on each comparison page.

    No vendor can pay to improve their Trust Score. The full 0 to 100 rubric (explicit pass thresholds, data sources, red flags, and what we deliberately don't score) is published at /vendors/methodology.
