The toolkit

Peptide dosage calculator.

Three numbers — how much peptide is in the vial, how much diluent you add, and the dose you are studying. You get the concentration, the volume to draw, and the units.

Quick presets
mg

Total peptide in the vial, as printed on the label or COA.

mL

Bacteriostatic water you add to the vial.

A calculation input from your research reference — never a suggested dose.

Units are shown for a U-100 syringe — 100 units per mL, the standard for research use. The volume in mL is the same on any syringe; only the markings differ.

0.200 mL · 20.0 units
Concentration
2.50 mg/mL · 2,500 mcg/mL
Volume per dose
0.200 mL · 20.0 units
Target dose
0.5 mg
Doses per vial

5 mg ÷ 2 mL = 2.50 mg/mL · 0.5 mg ÷ 2.50 mg/mL = 0.200 mL

About this peptide dosage calculator: enter your vial amount (mg), diluent volume, and target dose to get your reconstitution concentration in mg/mL and mcg/mL, the volume per dose in mL and units on a U-100 syringe, and total doses per vial. Research calculation tool — it does not recommend doses or establish suitability for human use.

Evidence standards

What does the research actually say?

A Reddit comment and a randomized human trial are not the same level of evidence. Every guide here separates them, labels them, and links to the source.

Weaker evidence isn't worthless — it's just less certain, and you deserve to know which kind you're reading before you act on it.

  1. 1Human randomized and controlled trials
  2. 2Other human clinical evidence
  3. 3Observational and case evidence
  4. 4Animal and preclinical research
  5. 5In-vitro and mechanistic research
  6. 6Practitioner-reported protocols
