Compound X exists to give researchers in the US, UK, Canada and Australia one place to compare real vendor pricing, testing claims and published research on SARMs, peptides and nootropics — side by side, without the hype. For research purposes only.
The research write-up and the vendor comparison live on the same page — so you can see what the evidence actually shows before you decide where to buy.
Every compound guide cites real published research where it exists — trial design, dosing, sample size. Where the human data doesn't exist yet, we say so directly instead of implying otherwise.
Every vendor comparison table discloses whether purity testing is third-party verified or in-house only — that distinction is never hidden to make a listing look better.
A few links on this site are affiliate links — they're disclosed in the footer, and they never change what we say about a compound.
Everything on this site is written for laboratory research purposes, not as medical or consumption advice.
Vendor rankings and reviews reflect our own editorial assessment of testing transparency, catalog breadth and pricing — not payment, and not customer-submitted star ratings.
Third-party COA vs in-house testing is shown on every vendor row — we don't let a testing gap disappear into fine print.
Every affiliate relationship is disclosed on every page that has one — in the footer and, where relevant, inline.
This is our own assessment of catalog range and testing transparency — no vendor can buy a higher spot on this site.
Every category page compares vendors and cites the underlying research — not just a product blurb.
RAD-140, LGD-4033, Ostarine, S4 and more — trial data, mechanism and vendor sourcing.
