What you can contact us about

Calculator questions — what a result means, how an input is interpreted, or how to apply a result to your own setup.
Methodology feedback — if you believe a formula should be presented differently, or if a worked example looks off, we'd like to hear it.
Error reports — if you spot a result that does not match the displayed formula, please tell us. The page will be corrected and the change logged on the editorial-policy page.
Calculator suggestions — if there is a peptide tool the site does not yet cover and you think it would be useful, send the topic and the formula.
Press & partnerships — media, education, or research collaborations.

What we won't respond to

Personal dosing, prescribing, or sourcing questions.

This site does not give medical advice, recommend a dose for a person or animal, or recommend vendors. If you need clinical guidance, speak to a licensed prescriber. If you need a research protocol, follow the protocol approved by your principal investigator or supervising pharmacist.
