This is not medical advice
Everything on SupplementCycle is educational. It is not medical advice, not a diagnosis, not a prescription and not a recommendation to take anything. Nothing here creates a clinician-patient relationship, and — as /about says plainly — no doctor, pharmacist or regulator is behind the site.
The dosing protocols, timelines and calculator outputs describe what the cited literature reports. They are not instructions. Talk to a doctor before acting on any of it, particularly if you take prescription medication, are pregnant or breastfeeding, or have a diagnosed condition.
Legality is yours to check
Many compounds documented here are prescription-only, unlicensed, or controlled. In the UK anabolic steroids are Class C under the Misuse of Drugs Act, and several peptides covered on this site are not authorised for human use anywhere.
Documenting a compound is not an assertion that obtaining or using it is legal where you live, and the legal status of the same substance differs sharply between countries. Checking your own jurisdiction is your responsibility, not ours.
We sell nothing
SupplementCycle is not a pharmacy, a vendor or a broker. It sells no compounds, supplies none, and sources none. We do not answer questions about where to buy anything, and we do not put readers in touch with people who do.
The site carries advertising, and some outbound retailer links may in future pay a commission — those will be labelled where they appear. Neither buys any influence over which compounds are listed, how they rank, what the evidence tiers say or what the safety flags warn about. That commitment is set out on /about and it is load-bearing.
Accuracy, and the limits of it
Pages are assembled from cited sources under the rules on /methodology, and where the human evidence is thin the page says so. That is care, not a guarantee. The literature moves, regulatory status changes, and a page can be wrong or out of date. Nothing here is warranted to be accurate, complete or fit for any purpose, and you rely on it at your own risk.
Found a mistake? That is the single most useful thing you can send us — see contact.
Saved cycle plans
Saving a plan produces a share link that anyone holding it can open. Treat it as public. The plans are a convenience rather than a service we promise to keep running — they may be removed, and you should not rely on one as a record of anything.
Content and reuse
The writing on goals, stacks and conditions, the taxonomy, the calculators and the design are ours. The compound catalogue — its structure and much of its descriptive text — comes from the open-source peptide-db project, reused under the MIT licence and corrected, restructured and extended here. That licence asks for one thing in return, its notice, which follows. Quote us with attribution and a link; do not republish the catalogue wholesale or scrape the site.

The cited sources — trials, PubMed records, regulatory documents — belong to their own publishers and carry their own terms. The open-source software the site is built on is listed, with each package's licence, in the third-party notices.
Trademarks
Brand names that appear on the site — Ozempic, Winstrol and the rest — and the companies behind them are trademarks of their respective owners. They are used to identify the compound under discussion and for nothing else. SupplementCycle is not affiliated with, endorsed by or sponsored by any manufacturer, retailer, regulator or institution.
Liability
To the fullest extent the law allows, we are not liable for any loss, injury or damage arising from the use of this site or anything read on it. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded.
Governing law
These terms are governed by the law of England and Wales, and its courts have exclusive jurisdiction. If you are a consumer elsewhere, this does not remove protections you have under the mandatory law of the country you live in.
Changes
These terms change when the site does; the date at the top moves with them. Continuing to use the site after a change means you accept it.
