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 a free account drops the count 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. The account is free too.
Every calculator and tool is free. A free account adds alerts on the peptides you save: legal or FDA changes, safety updates and new human studies. It adds dose reminders, supply counts and calendar sync too.
Pick a peptide. See the schedule first. Save it when it fits.

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.
