Free tools, expert protocols, and transparent sourcing.
Protocols from 24 researchers, clinicians, and biohackers
Browse by Goal
Pick your goal. Find the right peptides.
Built to be trusted
Two evidence streams, supply counts from your own logs, and tools that are free to use.
Two kinds of evidence, side by side.
Published trials on one line. Community reports and votes on the other. Neither one gets buried.
Doses left, counted from your logs.
Log a dose and the count drops on its own. At 3 doses or fewer, or 7 days from running out at your pace, the vial is flagged. With calendar sync on, a heads-up lands about 4 days before it runs out.
Free to use, with or without an account.
Every calculator and tool works without an account. Dose logging, reminders, supply counts, and calendar sync need a free one.
Popular Expert Protocols
Real protocols from researchers, clinicians, and public figures who have published their dosing.
How It Works

Common Peptide Schedules at a Glance
A quick reference for the most-asked dosing schedules. Click any peptide for full protocols, citations, and a per-vial calculator.
| Peptide | Typical Frequency | Cycle Length | Goal |
|---|---|---|---|
| BPC-157 | Daily, often twice | 4–6 weeks on, 2–4 off | Healing |
| TB-500 | 2–3× per week | 4–6 weeks loading, then maintenance | Healing |
| Semaglutide | Once weekly | 16–20 wk titration, then maintenance | Weight loss |
| Tirzepatide | Once weekly | 20 wk titration, then maintenance | Weight loss |
| CJC-1295 + Ipamorelin | AM + before bed | 8–12 weeks on, 4 off | GH support |
| MK-677 | Daily, evening | 3–6 months, 1 month off | GH / sleep |
| PT-141 | As needed | 1–4 hr before activity, <2 mg / 72 hr | Sexual wellness |

How the Math Works
Peptide Schedule turns three inputs into exact syringe units: vial size (mg), bacteriostatic water (mL), and dose (mcg). It covers 1mL, 0.5mL and 0.3mL U-100 syringes, plus veterinary U-40. Every peptide in the database ships with recommended vial sizes, BAC water amounts, and three dosing tiers (beginner, moderate, aggressive).
The Reconstitution Math
- Concentration (mcg/mL) = Vial mg × 1000 ÷ BAC water mL
- Draw volume (mL) = Dose mcg ÷ Concentration
- Syringe units = Draw volume × Units per mL
You do not have to memorize this. The calculator runs every step automatically.
