Why we send everyone to ZestyRat.
We tried the market. We stopped at one lab. Here's the receipt.

The short version
We've put more than 70 orders through ZestyRat Research. Not one has gone missing. Not one vial has arrived with a broken seal or a label that didn't match the last one. Every batch has a published third-party test. And the number that actually matters to a buyer's guide: over 90% of the people we send there come back and order again — monthly, and often more. Nobody reorders from a vendor that burned them.
What "reliable" means in this market
About a third of research peptide vials on the open market fail independent purity testing. The failure modes are boring and expensive: under-dosed vials, wrong compound, bacterial contamination, packages that never ship. So "boring" is the most valuable thing a vendor can be. Nobody wants an interesting story about where their peptides came from. ZestyRat is boring in exactly the right way.
What we verified on their site (not what we assume)
- 99%+ minimum purity, independently tested per batch.
- Induction-sealed vials.
- Plain, unlabelled packaging with tracking on every order.
- USPS Priority or UPS, 1–3 business days, from a real US address in Grovetown, Georgia.
- Founder-led company with a phone number that gets answered.
- Strict all-sales-final policy — lost shipments replaced free on first occurrence, damage claims need photos quickly. We tell you this up front because a vendor that's honest about its limits is one you can plan around.
What we don't do
We don't invent a second-place vendor to look balanced. We don't run coupon cards for three different labs. We don't pretend to be a store. One lab, one code, every page.
The code
SHAUN10 takes 10% off every order at checkout, every time, no expiry. It's attached to our affiliate ID, which is how we get paid — at no cost to you.
Frequently asked
Is CD Biolab a peptide vendor?
No. We're an independent buyer's guide and affiliate. We send every customer to ZestyRat Research and earn a commission on orders through our links.
Has ZestyRat ever messed up one of your orders?
Not in 70+ orders. The only hiccups we've seen are a customer's own checkout failing and being retried — the vendor side has been clean.
What if something arrives damaged?
ZestyRat's policy is all sales final, with lost shipments replaced free on first occurrence and damage claims needing photos promptly. Photograph everything on arrival.
