THE PROCESS
FOUR STEPSBuild your order
Pick your compounds, lots, and quantities from the catalog. The minimum is 50 vials (5 kits) across the order, in 10-vial kits — mix as many compounds as you like.
Add your details
Add your ship-to details — and a resale certificate if you have one. It's welcome, not required.
We confirm it
Your order totals at the volume tier your kit count earns. Our US team confirms the total and lead time in writing, typically within a few hours during business hours.
We ship it

WHOLESALE FAQ
7 ITEMSDo you sell to the public?
No. Peptide Wholesalers sells to resellers and institutions only. There is no public checkout — wholesale pricing is published on every product page, and you send us your order, which our team confirms in writing before anything ships.
What are the minimums?
The minimum is 50 vials (5 kits) across the whole order — not per compound. Compounds are ordered in 10-vial kits, so you can mix several peptides in one order as long as the total clears the minimum. Volume tiers also apply order-wide: 10 kits mixed across ten compounds earns the same discount as 10 kits of one.
Do I need a resale certificate?
It's welcome but not required to place an order. If you have one, add it when you send your order.
Where do orders ship from?
Every lot is stored and shipped from our warehouse in Costa Mesa, California. Orders in by noon Pacific ship the same business day.
What does shipping cost and how long does it take?
$35.00 flat shipping for orders up to 400 vials, within the United States. Orders in by noon Pacific ship the same business day from Costa Mesa, California, by UPS 2nd Day Air and arrive in 1–2 business days — about 1–2 days in California, around 2 nationwide. UPS Next Day Air is $100.00 for orders up to the same size. Very large orders and special destinations are quoted individually. Cold-chain packaging, where a compound requires it, is quoted and billed separately.
Can I return an order?
Research peptides are not returnable once shipped: sealed vials and chain-of-custody mean a returned vial cannot be released to another buyer. If a shipment arrives damaged, incomplete, or is not what you ordered, contact the desk and we will make it right.
Is there a certificate of analysis for every batch?
Yes. Every new batch is tested by Kovera Labs before release — identity, quantity, purity, endotoxins, heavy metals, and sterility — and its certificate is batch-specific, filed in the public library and searchable by lot number.
