Peptide Blueprint
Sourcing

The supplier network most operators take 2 years to find.

47 vetted labs across China, the US, and EU — each personally audited for purity, consistency, and shipping reliability.

47 Vetted Labs

Direct contacts at top Chinese GMP facilities, US compounding pharmacies, EU research suppliers — pre-vetted for purity, consistency, and shipping reliability.

Real COA Verification

How to read HPLC, mass spec, endotoxin, and residual solvent reports — and the 6 tells that flag forged certificates.

Sample Protocols

5-vial double-blind testing, third-party verification labs (Janoshik €60/test, Ascend, Krotov), batch-to-batch consistency tracking.

Freight & Customs

DDP vs DDU, Hong Kong consolidation, freight forwarder shortlist, HTS codes, four shipping methods that actually clear US customs.

Quality Tiers

Pharma-grade vs research-grade, freeze-dry standards, cold-chain requirements — and which suppliers to use for which SKU.

Negotiation Scripts

Word-for-word MOQ, payment terms, exclusivity, and Net-30 scripts that drop COGS 30–50%.

The directory, by tier

47 suppliers, sorted for you.

Tier 1 — Pharma Adjacent
8 suppliers

GMP-equivalent facilities serving research markets. Highest purity (>99%), highest cost, longest lead times. Best for premium brands and flagship SKUs.

Tier 2 — Established Research
23 suppliers

The workhorse tier. 97–99% purity, reliable shipping, reasonable MOQs. 80% of operators source here.

Tier 3 — Volume / Generic
16 suppliers

Lowest cost, higher variance. Good for fast-moving SKUs once you have QC dialed in. Always third-party verify.

The 5-step supplier qualification

  1. 01

    Initial outreach

    Use the cold email template. Request product list, MOQ, lead time, and 3 recent COAs from different batches.

  2. 02

    Sample order

    Buy 2–3 SKUs at sample-pack pricing. Pay via the supplier's preferred B2B method (typically wire or bank transfer). Track shipping pattern, packaging quality, and communication speed.

  3. 03

    Third-party verification

    Send vials to Janoshik (€60) and Ascend Analytical. Verify peptide identity, purity (>95%), endotoxin levels, and contamination. Compare results across labs.

  4. 04

    Pilot run

    Order 50–100 vials per SKU. Sell to your existing list at slight discount. Track customer feedback, side-effect reports, and reorder rate over 30 days.

  5. 05

    Lock terms

    Negotiate Net 30, regional exclusivity (or first-right-of-refusal on new SKUs), and white-label packaging at 500-vial+ orders.
