If you have arrived at americanpeptides.us with a compound in mind, the whole process from first click to confirmation email can be done in a few minutes. There is no account to create, guest checkout is available, and the 20% discount code PEPSAVE20 is applied in a single field at checkout rather than at any earlier stage. Everything is sold for laboratory research use only, and you certify at checkout that you are a qualified researcher of legal age.
The top navigation carries Shop, Bundles, Merch, COA, Learn, Partner Program, Why Us, Wholesalers, Blog and Support. The fastest route is the Shop menu or the category collections, which split the 68 listed research compounds into nine groups: GLP-1 & Metabolic, Research Peptides, Peptide Blends, Liquid Sprays, Dissolving Strips, Bioregulators, Research Bundles, Lab Supplies and Merch.
Two things slow people down at this stage. First, several items are multi-strength — retatrutide, tirzepatide, semaglutide, BPC-157, GHK-Cu, NAD+, SS-31 and tesamorelin all appear in more than one strength, and vial sizes such as 10 mg and 60 mg are separate line items. Pick the exact line item you need rather than assuming a single listing covers all sizes. Second, individual vials range from roughly $40 for ipamorelin to $170 for cagrilintide, with BPC-157 at $60.00 as a one-time purchase, so the total you are discounting depends heavily on which strength you select.
Before you move to checkout, it is worth deciding on the three variables that interact with the code:
Free shipping applies to orders over $300. The site does not state whether that threshold is measured before or after the discount, so check the shipping line at checkout rather than assuming.
Quantity tiers drop the per-unit price by 7% when you add two more units.
Research bundles are already pre-discounted and marked 'SAVE 10%', priced $247.50–$292.50 for three compounds; subscribe-and-save is worth up to 15%, for example $9.00 off every delivery on a $60 vial. Whether PEPSAVE20 stacks with bundle or subscription pricing is not stated, and you should assume one discount code per order.
If you are adding consumables, reconstitution solution is $30.00 and alcohol prep pads are $6.99.
Open the cart drawer and click checkout, confirming quantities first.
Enter your email, shipping address and shipping method on the single-column checkout form.
Find the discount code field in the order summary, above the subtotal. On desktop it sits in the right-hand column; on mobile it is hidden until you tap 'Show order summary'. The exact label may read 'discount code' or 'gift card'.
Type PEPSAVE20 in capitals with no spaces and press Apply.
Check that the discount line shows 20% off the product subtotal — it does not apply to shipping or tax — and glance at the shipping line.
Complete payment with 'Pay now' and keep the confirmation email.
Retroactive application after an order is placed is rarely possible, so the moment between applying the code and pressing 'Pay now' is the one that matters.
Orders placed before 2PM EST ship the same day from the US facility. Packaging is plain and unmarked with a generic return address, and the billing descriptor is non-descript. Every lot has a Certificate of Analysis you can download free from the COA section; batches are verified by the independent laboratory Bioviridian using HPLC-MS purity, MALDI identity and endotoxin screening, with listings referencing at least 99% purity by mass spectrometry and COAs also covering heavy metals. A Safety Data Sheet in GHS format is available for most items.
Inspect the delivery promptly. A broken vial or wrong product is replaced free if you notify within 72 hours, and transit damage or a wrong item must be reported inside that window. Support tickets can be opened without an account, which fits the guest-checkout route.
There is a year-round programme for active military and first responders, but it requires separate verification and is not part of the quick path described above. If you want that pricing, handle the verification before you build a cart rather than after.
