PSPeptides Coupon Code (2026): CHECKED for 10% Off

The PSPeptides coupon code is CHECKED, and it gives 10% off your order. It's our code, last verified September 26, 2026. PSPeptides doesn't publish coupon terms we could find, so check the discount line at checkout before you pay. The code has no effect on how we score PSPeptides (8.5/10).

Notice: Research peptides are sold for in-vitro laboratory research only. They are not FDA-approved, not for human or animal consumption, and this page is not medical advice.

PSPeptides code at a glance

Disclosure: PeptideChecked has an affiliate relationship with PSPeptides. We may earn a commission if you buy through our link or use this code. That doesn't change its rating, which comes only from our published method.

How to apply the code

1. Go to PSPeptides through our link or type pspeptides.com.
2. Add items to your cart.
3. Look for the coupon or discount-code field in the cart or at checkout, and enter CHECKED.
4. Apply it and confirm a 10% discount line appears before you pay.

If the discount doesn't appear, the likeliest reasons are a typo, an item or bundle the vendor excludes, or a change in the vendor's terms. Contact PSPeptides support before you place the order. We can't apply or honor codes ourselves.

What the code covers, and what we couldn't confirm

We checked PSPeptides' public pages on September 26, 2026, looking for coupon terms:

• Homepage: the homepage advertised free shipping on any order and free UPS 2nd Day Air on orders over $200 (checked September 26, 2026). It also showed sale prices on individual products and discounted bundles. It didn't mention coupon rules.
• Terms and FAQ: we couldn't load a terms-and-conditions or FAQ page at the usual addresses, so we found no written stacking or exclusion rules.
• Affiliate page: the affiliate registration page describes the partner program but doesn't state what discount customers get or any restrictions.
• Cart: the cart page blocks automated access, so we couldn't test the code on specific items.

So we can't say whether CHECKED applies to items already on sale, to bundles, or to shipping upgrades. Coupon terms are set by the vendor and can change at any time. Treat the checkout total as the answer.

What 10% saves at current prices

PSPeptides priced BPC-157 at $49.99 to $89.99 depending on size, and the Shred Express bundle at $224.99 on sale, when we reviewed it (shop). If CHECKED applies to those items, 10% off works out to:

That's simple arithmetic, not a quote. Prices and sale discounts change often, and we couldn't confirm whether the code applies on top of sale prices. The order total at checkout is what you'll pay.

Before you use it: how PSPeptides scores

A discount only matters if the vendor meets your documentation needs. Here is the short version of our PSPeptides review.

Pros

• Dated COAs for about 60 products. The certifications page lists certificates dated by month, each with a test ID.
• A named lab on the certificate we opened. The retatrutide 40mg COA was issued by North American Diagnostics and showed a batch number and method.
• Wide payment options: cards, Apple Pay, Google Pay, Shop Pay, Cash App, Zelle, Afterpay and Klarna (payment options).
• No FDA warning letter found in the FDA database as of September 26, 2026.

Cons

• Dosing guides on its blog. This is the biggest red flag. The blog publishes human dosing content, such as a week-by-week retatrutide dosage chart. That conflicts with the research-use-only labeling on its products. We don't repeat any of it.
• Benefit-style bundle names such as "Shred Express" and "Turn Back Time" (shop).
• Lab not named on the site. The lab appears only on the PDFs, and the certificate we opened listed no accreditation or verification key.
• Hard-to-verify claims. It says it has been in business for over 5 years, but the domain was registered in November 2025 (WHOIS). Its US manufacturing and cGMP claims are unverified.
• No independent data. Finnrick lists the vendor with 0 tests.

FDA has said a "research use only" label doesn't protect a seller whose content points to human use (background). That's why PSPeptides has the lowest score of the eight vendors we list.

How to check your order's COA

A 10% discount doesn't change what's in the vial. After ordering:

• Find the batch or lot on your label and look for the matching certificate on the certifications page.
• Check the lab name, test date, method and purity. Our COA guide and COA checklist walk through the fields.
• If the lab offers a lookup, confirm the report there. North American Diagnostics' website offers a batch lookup.
• For lab-handling unit math, use our reconstitution calculator.
