The rules for using this site, and the limits of what the material here is for.
By accessing OptimalDosages.com you agree to these terms. If you do not agree with any part of them, please do not use the site. Continuing to use the site after these terms change means you accept the revised version. Last updated 18 August 2026.
This site does two things. It performs reconstitution arithmetic — the maths that converts a vial strength and a volume of diluent into a concentration and a syringe reading. And it indexes dose figures reported in published literature, with the evidence tier for each compound stated openly.
We sell nothing. There is no checkout, no cart and no product on this site.
Nothing on this site is medical, pharmaceutical, veterinary or professional advice, and no doctor–patient or other professional relationship is created by your use of it. The figures published here are bibliographic reference: a record of what has been reported in research, not a recommendation that any dose is safe, effective or appropriate for you or for anyone.
Many compounds indexed here are unapproved investigational substances. Some have human safety data; several have none at all. Nothing on this site has been evaluated by the U.S. Food and Drug Administration, and nothing here is intended to diagnose, treat, cure or prevent any disease. Consult a qualified clinician before acting on anything you read here.
We would rather tell you how this was built than let you assume. As set out in our editorial policy, the dose ranges and citations on this site were assembled by an AI system from its knowledge of the published literature, and the individual citations have not been verified against source records. Author names, journals and years may contain errors. Treat the ranges as a starting point for your own reading and follow the links to the source.
The arithmetic is deterministic and we believe it is correct, but you are responsible for checking any number before you rely on it. We make no warranty that the content is accurate, complete or current.
You agree not to use this site to break the law, and to comply with the rules that apply where you are — including any law governing the purchase, possession, import or administration of the substances indexed here. Those rules vary enormously between countries and it is your job to know yours.
You also agree not to scrape, bulk-download, mirror or republish the dataset, not to interfere with the site's operation or security, and not to present material from this site as medical guidance to anyone.
The text, structure, compiled dataset, design and code of this site are ours and are protected by copyright. You may read, print and link to pages for your own reference. You may not republish substantial portions commercially without permission.
Compound names, trade marks and study citations belong to their respective owners and appear here for identification and reference only.
Some links on this site are affiliate links, including links to Amazon. As an Amazon Associate we earn from qualifying purchases. Buying through them costs you nothing extra and does not affect what we publish. Our privacy policy explains how that tracking works.
We link to outside sites, including literature databases and a peptide supplier. We do not control those sites and are not responsible for their content, their accuracy, their products or their privacy practices. A link is not an endorsement of everything on the other end of it.
This site is provided "as is" and "as available", without warranties of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement.
To the fullest extent permitted by law, we are not liable for any direct, indirect, incidental, consequential or special loss or damage arising from your use of this site or from reliance on anything published here — including any loss or injury connected with the handling or administration of any substance. You use this material entirely at your own risk.
Nothing in these terms limits liability that cannot lawfully be limited, including liability for death or personal injury caused by negligence, or for fraud.
If any provision of these terms is found unenforceable, the rest remain in force. We may update these terms and will change the date above when we do. We may modify or discontinue any part of the site at any time.
