Disclaimer & Legal Notice

Last updated: August 2026

PeptideClock is a set of reference tools and educational articles about peptide stability, storage, and handling. The calculators on this site run mathematical models — chiefly a first-order decay model — and the articles summarize published stability evidence with explicit confidence labels. That is the entire scope of the site. It is not a pharmacy, a clinic, a laboratory service, or a vendor, and it sells no peptides.

Not medical advice

Nothing published here constitutes medical advice, diagnosis, or treatment. Reading this site, or using any of its tools, does not create a doctor-patient or any other professional relationship. If you are making a decision that affects your health — including decisions about any prescription product such as semaglutide or tirzepatide — that decision belongs with a licensed healthcare professional and the official product labeling, not with a stability calculator. Where this site summarizes FDA labels, the label itself is always the authoritative document.

Research use only — not for human consumption

Many of the compounds covered in the peptide database are sold as research chemicals. They are not approved by the FDA for human use, their manufacturing is not held to pharmaceutical quality standards, and their labels typically state "not for human consumption" for exactly those reasons. PeptideClock's stability estimates for such compounds exist to support research documentation and storage planning. They are not — and must not be read as — guidance for self-administration, and nothing on this site encourages any use of these substances that violates the law in your jurisdiction.

Accuracy and model limitations

The potency figures produced by our calculators are estimates, not measurements. Where a number comes from the internal model rather than a published study or product label, the site labels it a model estimate, and those labels mean what they say: no assay was run on your vial. Real-world stability is also affected by factors the model cannot see — manufacturing quality, light exposure, vibration, container surfaces, and handling technique among them. Two vials of the same peptide can degrade at meaningfully different rates. Treat every output as a planning aid with uncertainty attached, and rely on the site at your own risk.

Affiliate disclosure

PeptideClock is a participant in the Amazon Services LLC Associates Program. As an Amazon Associate, PeptideClock earns from qualifying purchases made through some outbound product links. The products linked are general laboratory and handling supplies — syringes, cold storage, and similar equipment — never peptides themselves, and no affiliate relationship influences the stability guidance or evidence labels published on this site. Every page that carries affiliate links also carries its own disclosure notice.

External links

Articles link out to primary sources such as FDA labels, DailyMed, and PubMed, and occasionally to third-party retailers. We do not control those sites and are not responsible for their content, availability, or privacy practices. How we handle data on this site is described in the Privacy Policy.

No warranty and limitation of liability

All content and tools are provided "as is," without warranty of any kind, express or implied, including accuracy, fitness for a particular purpose, or non-infringement. To the fullest extent permitted by law, PeptideClock and its operator accept no liability for any loss or damage arising from the use of this site, including loss of research material attributed to reliance on a stability estimate.
