What is the half-life of BPC-157?
BPC-157 has a short plasma half-life, on the order of a few hours, which is why most protocols split it into daily or twice-daily doses. For your specific timing, confirm with your prescriber.
Not medical advice. Cannot prescribe or diagnose.

FAQ

Frequently asked questions

Last updated June 12, 2026

What is Vial?

Vial is a peptide, GLP-1, and TRT dose tracker for iPhone. You log every dose, set on-device reminders, and keep your vials, schedule, bloodwork, and notes in one private place. It supports BPC-157, TB-500, GLP-1s like semaglutide and tirzepatide, TRT, and custom compounds. Vial is free to start.

Is Vial really free?

Yes. Vial is free to start: one active protocol, your first vial tracked to the last dose, 14 days of history, bloodwork, body metrics, and progress photos, plus one AI coach message. Premium unlocks unlimited protocols, full history, CSV export, and unlimited Vial AI.

Is my peptide data private?

Yes. All protocol data, dose logs, and metrics are stored on your device in on-device SQLite. Nothing is uploaded, no account is required, and Vial does not track you across other apps or websites.

What peptides does Vial support?

Vial supports 15 built-in peptides: BPC-157, TB-500, CJC-1295 (with and without DAC), Ipamorelin, GHK-Cu, semaglutide, tirzepatide, retatrutide, Epitalon, NAD+, MOTS-c, Tesamorelin, Sermorelin, and PT-141, plus testosterone and HCG for TRT. Custom peptide entry covers anything else.

How much does Vial cost?

Vial Monthly is $14.99 and Vial Yearly is $49.99, with a $29.99 first-year intro for new subscribers. Vial Lifetime is $99.99 one time. The AI coach is included with every paid tier, and core dose tracking stays free.

What is Vial AI?

Vial AI is an educational chat assistant included with every paid tier. It explains peptide mechanisms, half-lives, technique principles, and published prescribing information. It cannot diagnose, prescribe, or recommend a dose, and is configured to redirect personalized clinical questions to your prescriber.

Does Vial work for GLP-1 and TRT, not just peptides?

Yes. Vial tracks compounded GLP-1 protocols like semaglutide, tirzepatide, and retatrutide, plus TRT and HRT regimens like testosterone, HCG, and ancillaries, alongside research peptides. Daily, weekly, and custom schedules are supported, including on and off cycle weeks.

Does Vial work offline?

Yes. Vial works fully offline with no account. Only Vial AI needs an internet connection, because it streams responses from a hosted model.
