American Peptides lists 68 research compounds across nine categories, and several of them appear more than once because strength is a separate line item. Retatrutide, tirzepatide, semaglutide, BPC-157, GHK-Cu, NAD+, SS-31 and tesamorelin all have multi-strength listings, and vial sizes such as 10 mg and 60 mg are sold as distinct products. That means the size and strength decisions you make in the Shop menu set the subtotal, and the subtotal is what PEPSAVE20 reduces by 20%. Choosing the wrong line item and then relying on the code to soften the cost is the wrong order of operations.
Prices for individual vials run roughly $40 for ipamorelin to $170 for cagrilintide, with BPC-157 listed at $60.00 as a one-time purchase. Supporting items are cheap by comparison: reconstitution solution at $30.00 and alcohol prep pads at $6.99. All of those sit in the product subtotal, so the 20% covers lab supplies as well as compounds.
The site applies quantity tiers: adding two more units drops the per-unit price by 7%. That reduction is built into the cart pricing rather than typed in, so it changes the subtotal before any code is applied. Research bundles work similarly — three-compound bundles are priced $247.50–$292.50 and are already pre-discounted, marked 'SAVE 10%'. Subscribe-and-save is worth up to 15%, for example $9.00 off every delivery on a $60 vial, with skip or cancel available.
What is not confirmed is whether PEPSAVE20 stacks with bundle, subscription or verified-programme pricing. The site's own terms should be treated as one discount code per order, and code stacking with those pre-discounted structures is listed as an unknown. If you are choosing between a tiered quantity of single vials and a pre-discounted bundle, price both baskets and watch what the discount line actually does after you press Apply.
Free shipping applies on orders over $300. Because the code cuts 20% from the product subtotal, a basket built to land just above $300 may fall below that line once the discount is applied — and whether the threshold is assessed pre-discount or post-discount is not stated. Check the shipping line in the order summary after applying the code rather than before. Same-day shipping is offered on orders placed before 2PM EST, and orders ship from a US facility.

The discount applies to the product subtotal, not to shipping or tax. No account is required and guest checkout is available. Retroactive application after an order is placed is rarely possible, so the sizing and the code both need to be settled before you pay.
Every lot has a lot-matched Certificate of Analysis, downloadable free, covering heavy metals as well as purity. Batches are verified by the independent laboratory Bioviridian using HPLC-MS purity, MALDI identity and endotoxin screening, and listings reference at least 99% purity by mass spectrometry. A Safety Data Sheet in GHS format is available for most items. Orders arrive in plain unmarked outer packaging with a generic return address and a non-descript billing descriptor.
Products are sold for laboratory research use only and are not for human or veterinary use. Buyers certify at checkout that they are qualified researchers of legal age. A broken vial or wrong product is replaced free if reported within 72 hours, which is the same window given for transit damage or a wrong item. Support tickets can be opened without an account.
