Capabilities
Everything under one roof. One accountable party.
The usual setup is a manufacturer in one place, a labeler in another, and a fulfillment house in a third — and when an order goes wrong, three vendors point at each other. Production, testing, labeling, and fulfillment all run out of our Costa Mesa facility. One account manager owns the whole chain.

- 03
Label
Private label designed, printed, and applied in-house. Your brand, your lot numbers.
- 04
Fulfill
Cold-chain warehousing at −20°C and 2–8°C, kitting, and lot-tracked pick-pack-ship.
- 05
Ship
Domestic outbound with tracking, under your brand or ours. No overseas handoff.
Why us
We don’t guess. We document.
Most wholesale peptide vendors hand you a SKU and a price. We hand you a qualified vendor chain, an independent batch test, and a per-lot certificate of analysis with every order — so you know exactly what’s in the vial.
01 · Source
Sourced in the USA.
Compounds are sourced through a controlled US supply chain with documented vendor qualification. Domestic distribution means no customs holds, no opaque chain of custody, and no surprises at the door.
02 · Verify
Third-party HPLC/MS on every lot.
Each production run is independently tested by a contract analytical lab. Identity, purity, and quantitation are documented per lot — not per product line.
03 · Document
Lot-tracked COAs, with every order.
Every batch is third-party tested. The per-lot certificate of analysis comes with every order at no charge, issued in the name of Wholesale Peptide Supply — searchable on /coa once released so your customers can verify the same lot independently.

Our process
From column to crate, in three documented steps.
The journey you followed above, as the checklist we run on every single lot — no exceptions, no untested releases.
Source
Sourced through a controlled US supply chain
Compounds are sourced through qualified vendors and routed through a domestic US distribution operation. Every inbound lot is logged, segregated, and held until release — no opaque overseas chain of custody.
Verification
Independent HPLC/MS analysis on every lot
Each production run is shipped to a contract analytical laboratory for HPLC coupled with mass spectrometry. Identity, purity, and quantitation are documented per lot.
Release
Lot-tracked, with the COA in every order
When the COA returns the lot is released and the lot number is searchable on our COA page. The per-lot PDF comes with every order at no charge, so your customers can verify the same lot independently when they need to.
FAQ

admin@wholesalepeptidesupply.comThe order minimum is 100 vials total — mix and match across any compounds to reach it. Volume pricing works differently: it is earned per compound, at 100 kits (1,000 vials) of that one compound, so mixing reaches the minimum but not the discount. Custom production runs and specialty blends have separate MOQs your account manager will quote directly.
Yes. Every order includes the per-lot COA documenting identity, purity, and quantitation for your specific lot, at no charge — there is nothing to add and nothing to ask for. Every certificate is issued in the name of Wholesale Peptide Supply; we do not issue certificates under a buyer's name, because a COA is a statement by whoever commissioned the testing. Endotoxin testing is available as an add-on procedure on request.
Yes. Submit your label artwork, assign your own internal lot codes, and specify cap colors. Custom-label orders carry a $20,000 order minimum and ship within 30 calendar days, because labeling runs as a dedicated production batch. If you don't have artwork, our team designs the label and sends you a proof inside that window.
In-stock catalog items ship in 1–2 business days. Custom production runs — non-standard doses and multi-peptide blends — fulfill in 7–10 business days. Custom-label and private-label orders ship within 30 calendar days. Overnight domestic shipping is available on every order.
All compounds are tested by an independent contract laboratory using HPLC coupled with mass spectrometry. The mass spectrum confirms identity; the chromatogram quantifies purity. Both are documented on the per-lot COA, which comes with every order.
Yes. Custom blends, compound combinations, and non-standard vial sizes are available by pre-order. MOQs and lead times vary by complexity — most requests can be quoted on the same day.
