How do I read a peptide reconstitution chart?

Find your vial strength down the left side and the amount of bacteriostatic water you added across the top. Where they meet is your concentration in mg per mL. The tables below then convert a dose into units.

What concentration should I aim for?

One that puts your usual dose between roughly 10 and 50 units on the barrel. That range is easy to read and a small misread costs you the least.

Does the chart change for different peptides?

No. The arithmetic is identical for every compound. Only the dose you look up changes, and whether it is written in mg or mcg.

Dose to units

All tables below assume a standard U-100 insulin syringe, where 100 units is 1 mL. On a U-40 syringe, multiply every number by 0.4.

Before you use these numbers This is a unit-conversion tool. It turns a vial strength and a water volume into a concentration, a draw volume and a syringe mark. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most compounds listed are sold for laboratory research and are not approved for human use. Nothing here is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always check the strength printed on your own vial rather than trusting a preset.
