How Wholesale Peptide Volume Pricing Works (and How to Reach the Next Tier)

Most peptide suppliers price per SKU in isolation, which punishes brands that want range. Marinexis prices wholesale orders by total volume: the more vials on the purchase order — across any mix of compounds — the lower the per-vial price on every line. Here's how it works.

Six tiers, one order

Wholesale accounts see per-vial pricing in six volume tiers: 100–249, 250–499, 500–999, 1,000–1,999, 2,000–2,999, and 3,000+ vials. The tier is set by the total number of vials on the order, not by any single product. Fifty vials of BPC-157, two hundred of NAD+, and three hundred of GHK-Cu add up to 550 vials — so every line is priced at the 500–999 tier.

The one rule: 100 vials per SKU

Each SKU on a wholesale order needs at least 100 vials. That's ten boxes, and it keeps production runs efficient enough to offer the tiered pricing in the first place. The portal flags any line below the minimum before you submit, and the team will confirm options by email if you need a smaller quantity on a specific compound.

How to plan for a better tier

• Consolidate orders. Two 400-vial orders a month sit in the 250–499 tier; one 800-vial order sits in 500–999. Same product, meaningfully lower per-vial cost.
• Mix compounds freely. Volume is counted across the whole order, so adding a second or third product helps every line, not just the new one.
• Watch the nudge. As you build an order in the portal, it tells you exactly how many more vials reach the next tier — sometimes a few dozen vials of something you already sell is all it takes.
• Plan around lead time. Most orders are produced to order in one to two weeks, so a consolidated monthly PO is usually easier to run than several small ones.

"Quote" items

Some compounds show "Quote" instead of a tier price. Those are priced by custom quote — usually lower-volume or specialty items — and are confirmed by email after you submit. They still count toward your order's total vial volume.

Clinic pricing is different

Licensed practices ordering for in-office use see a flat clinic price list, sold by the box of ten, with no volume minimum. Your account type at signup determines which list you see; the team can switch it or attach custom pricing to your account.

What's included either way

US cGMP manufacturing, 99%+ purity at release, a third-party COA on every lot, and pre-order samples at cost from the same lot. Freight is quoted separately, pricing is valid 30 days from quote, and nothing is charged through the website — invoicing is direct, Net 30 on approved accounts.
