About PeptideWiki
Research references and planning tools.
Your data
Calculator math runs in your browser. Chat messages and any figures you choose to include go to OpenAI. A shared plan link contains the plan itself; only share it with people you want to see those details.
Signing in is optional. It syncs your saved protocols, preparation, labels and tracking to your account so they follow you between devices. Signed out, these records stay in that browser only. Bookmarked reference pages do not sync.
We sell nothing. Some vendor links are referral links, and this site may earn from them.
How the math works
Reconstitution. Concentration is vial content divided by the final liquid volume after mixing. A U-100 syringe reads 100 units per millilitre, so 10 units is 0.1 mL.
Half-life. Each dose decays exponentially and overlapping doses stack. Build-up is read off the simulated curve, so uneven schedules like 5-on/2-off stay accurate.
Cost and vials. Only whole draws per vial count, so a leftover part-draw counts as waste. That is why "to buy" and "used" differ.
Limits
Calculators convert the figures you enter; they do not choose a personal dose. Beginner guides can prefill a clearly identified study or product reference, not an individualized dosing advice. There is no body-weight dosing field.
For most compounds here there is no human dose-ranging research to scale from. Adding a weight field would invent precision that does not exist.
Half-life figures for several short peptides are poorly studied. Where that is true, the compound page says so, and the curve is a rough model rather than a measurement. Amounts shown describe published research only.
Not medical advice
Nothing here is medical advice, a recommendation, or an instruction for human or veterinary use. Most of what is listed here is a research chemical rather than an approved drug; where one is a licensed medicine somewhere, its page says so. If you want care for a health condition, talk to a licensed clinician.
