One code, verified, with the fine print actually written down. We are a ZestyRat affiliate and we disclose it — which is also why we can tell you when a code is real.
| Code | What it does | Applies to | Fine print |
|---|---|---|---|
| SHAUN10 | 10% off product subtotal | Entire catalog — all ~50 compounds | No minimum order. Works for new and returning buyers. Does not discount shipping. |
| Newsletter signup | 10% off first order | First order only | ZestyRat's own on-site offer. First purchase only — SHAUN10 keeps working after that. |
Coupon sites routinely list "free shipping" next to ZestyRat codes. That is not what their policy says, and we would rather you know before checkout than after.
Straight from ZestyRat's published shipping policy, confirmed September 2026:
Short answer: yes — and we have a financial interest in saying so, which is exactly why we show our work. ZestyRat is the vendor our readers order from more than any other on this site, and to date not a single order placed through our links has come back with a problem reported to us.
The full breakdown, including what we do not love, is in our independent ZestyRat Research review. If you want to see how they stack against the rest of the market first, start with our peptide company rankings.

SHAUN10. It takes 10% off your order total and goes in the coupon field at checkout. It is not limited to first-time buyers and there is no minimum order.
Yes — 10% off the product subtotal across the full catalog of roughly 50 compounds, including BPC-157, TB-500, CJC-1295, NAD+, Semax and the GLP-1 category. It discounts products, not shipping.
No. Shipping is calculated at checkout on weight, dimensions and destination, per their published policy. Orders go out the next business day via USPS Priority Mail or UPS in plain, discreet packaging. Any page advertising free shipping on every ZestyRat order is inaccurate.
We cannot verify third-party codes from aggregator sites and we do not republish them. Oversized advertised discounts are common bait on scraped coupon pages and often fail at checkout. SHAUN10 is the code we stand behind because it is ours and we check it against the live checkout.
Yes, based on our independent review — 99%+ stated purity verified before dispatch, induction-sealed vials, founder-led with 22+ years in the field. It is the most-ordered vendor on this site with zero order issues reported to us. Full detail in our ZestyRat review.
There is no published expiration. We re-check it during our regular vendor audits and update this page if the offer changes.
Yes. Peptides Uncaged earns a commission when you order through our links or code, at no extra cost to you. We disclose it on every page per FTC guidelines, and it is why we publish the shipping terms other coupon pages leave out.
