PeptideClients is where serious operators source their inventory. Apply once, get a hosted storefront, a buyer inbox, lot-tracked inventory, and verified-purchase reviews. Every buyer on the marketplace is an admin-approved, paying operator — not tire-kickers and not the public. You and your buyer settle payment your way; we run the credibility layer around it.
No credit card. No setup fee. Review in 2–3 business days.
Most marketplaces want you to bring your own infrastructure. PeptideClients ships the storefront, the inbox, the order tracking, the lot management, and the verified-purchase review system — you ship the product and settle payment your way.
Every account is an admin-approved operator — research labs, clinics, compounders, fulfillment shops. Buyers pay for marketplace access, so the POs landing in your inbox come from operators with real intent and budget — not tire-kickers, not the public, no consumer chargebacks.
A hosted profile at shop.peptideclients.com/@yourhandle, a product catalog with COA uploads, and a buyer inbox threaded to orders. No Shopify subscription, no separate help-desk tool.
Buyer-submitted purchase orders with vendor approve/revise/deny, full revision history, per-lot inventory tracking, tracking-number capture with Shippo status sync, and verified-purchase reviews that only unlock after the buyer confirms receipt. Payment is between you and your buyer — we do not process payments, hold funds, or issue payouts.
Operate under multiple brands or run a sister lab? Manage every storefront from one vendor login. Switch contexts the same way operators switch between their stores in the back office.
Three steps, no sales call required.
Submit your business details, agree to the marketplace terms, and reserve your public handle. Vendor accounts live on their own login at sell.peptideclients.com — separate from any operator-app account you may already have, so the two contexts stay cleanly partitioned.
A PeptideClients admin reviews your application. We’re looking for legitimate, compliance-aware operators with a real fulfillment process. We may follow up with questions; we won’t leave you waiting.
Set up your profile, upload your catalog with images and lab docs, register your lots (with per-lot COAs and quantities), and list the payment methods you accept so buyers know what to expect. The first time you click “Publish,” your store is live on the marketplace and ready to receive purchase orders.
Five product types map to the marketplace catalog. The same listing form covers all of them — you upload images, set price, register lots with optional COAs, and publish.
Research-grade peptides in standard concentrations and volumes. Register each batch as its own lot so buyers see remaining quantity, expiry, and per-lot COA at a glance.
Operator-spec blends and custom concentrations. Use the per-order chat to confirm specs before you approve the purchase order.
Bulk peptide APIs and intermediates. Set minimum and maximum order quantities on the listing so buyer POs land in your inbox already inside your fulfillment range.
Compounding hardware, scales, sterile vials, lyophilizers, glassware, cold storage. List one unit per lot if each has a serial; multiple units per lot if they’re identical.
COA testing, custom compounding, regulatory consults, contract manufacturing. Buyers submit a PO describing the scope; you approve or counter with revised pricing.
PeptideClients does not process payments, hold funds, or issue payouts. You and the buyer settle directly — wire, ACH, crypto, escrow service of your choice, your existing merchant account — whatever you both agree on. We run the order pipeline, the tracking, the lots, and the reviews around it.
Eight tools shipped on day one. No add-ons to buy, no integrations to wire up.
