Bulk Peptide Calculator: Stock Up & Save
Running the same protocol for months? Buying your peptides in bulk drops the per-vial cost instead of paying full price one vial at a time. Build a basket below and the calculator shows your stacked total and effective price per mg in real time.
How bulk peptide pricing works
Two discounts stack, and they compound — the second applies after the first:
- Volume tier. Every vial in your basket counts toward one combined total. Hit a threshold and a percentage comes off the whole order — bigger baskets reach deeper tiers.
- Coupon code. A coupon then takes more off the tier-discounted subtotal — not the original list price — so the savings layer.
The more vials you stock for a multi-month protocol, the lower your effective $/mg. The calculator does the math live.
Build Your Bulk Basket
Add each peptide, pick a vial size, and set how many vials. Every vial in the basket counts toward the volume tier — the more total vials, the deeper the per-vial discount — and the 25% thepeptidecatalog code stacks on top.

Bulk peptide buying FAQ
How much can you save buying peptides in bulk?
It depends on how many vials you order. Per-vial volume tiers lower the price the more vials you stock, and a coupon code applies on top of that tier price. A larger multi-month basket can land well below the list total once both discounts stack. Use the calculator above for an estimate on your exact basket.
Do the volume discount and coupon stack?
Yes. The calculator applies the volume tier first — taking a percentage off the list subtotal based on your total vial count — then applies the coupon code to that already-reduced amount. The two discounts compound rather than replace each other.
How many vials do I need to reach the next discount tier?
Every vial in your basket counts toward the same total, regardless of which peptide it is. The calculator shows your current tier and tells you exactly how many more vials reach the next one. Mixing several peptides into one order is the fastest way to climb tiers.
Is buying peptides in bulk worth it?
If you run a consistent multi-month protocol, stocking up lowers your effective $/mg and cuts repeat shipping. The trade-off is storing more lyophilized vials — kept cold and dry, they hold well past a single cycle. Buy only what you'll realistically use within your storage window.
Does this calculator place an order?
No. It estimates your stacked total so you can plan a stock-up before you check out. The Peptide Catalog connects researchers with vendors and does not sell or fulfill orders — confirm the final price on the vendor's site at checkout.
