Medical disclaimer

Every calculator on Pepteca converts the numbers you type in: milligrams to millilitres, millilitres to syringe units, a percent solution to mg per drop, a lab value to an estimate. None of them tells you what dose to take, whether to take anything, or whether a number is right for you. They also cannot check that what you entered matches your vial, your prescription or your syringe.

Check every result against your prescription or the pharmacy label before you draw. If anything looks off, ask the pharmacist who filled it. Always verify with a licensed provider before starting, changing, or stopping any protocol.

Dose figures on Pepteca carry one of two labels. A study figure is what a trial or an FDA label used, in the people that source studied, who may not be like you. A community figure is what people report doing. It is not clinically established, and we show it so you can tell the two apart, not as a recommendation. How we verify sources is on the about page.

Many peptides covered here are not approved for human use and may be regulated differently where you live. Some compounds, like the GLP-1 medications and testosterone, are prescription drugs, and testosterone is a controlled substance in the US. Pepteca sells nothing you inject, lists no suppliers and takes no vendor money. For the current rules, see peptide regulation in 2026.

The pet pages are education, not veterinary advice. Doses that work in people or in lab animals do not carry over safely to dogs, cats or horses. Talk to your vet before giving your animal anything.

If you think you are having a serious reaction, call your local emergency number now. For a possible overdose or a wrong dose in the US, Poison Control is 1-800-222-1222.

We cite our sources and date every review, but guidance changes and mistakes happen. Each page shows when it was last reviewed. Information that was correct on that date may not be correct today, so check the linked source for anything you are going to act on.
