PEP 1 is the world's first AI model built for peptide research. Ask it about a peptide and it answers from the published research, with the sources beside the answer so you can open them.
Twenty compounds to start
PEP 1 opens with the 20 compounds people ask about most:
- Metabolic: semaglutide, tirzepatide, retatrutide, liraglutide, and AOD-9604
- Recovery and skin: BPC-157, TB-500, and GHK-Cu
- Growth hormone: CJC-1295, ipamorelin, sermorelin, tesamorelin, and MK-677
- Sleep, focus, and longevity: Selank, Semax, DSIP, and epithalon
- Hormones and pigmentation: PT-141, kisspeptin-10, and Melanotan II
For each one, PEP knows how it works, what the studies found, the side effects they reported, and what it interacts with.
Answers you can check
Every answer lists its sources. PEP also searches the published literature as you ask and shows the papers it found, each with a link to the paper itself.
Shaped by your profile
Tell PEP your goals, your medications, and your conditions once. When a question touches a known interaction, the warning appears with the answer.
What's next
Twenty compounds is the start. The library grows from here, and so does the depth behind each answer.
