Peptide Dosage Guide

Which peptide are you using?

Selecting a peptide loads its dosing schedule, reconstitution, supplies and mixing steps.

§ HOW THIS WORKS

Frequently asked questions

How do I calculate my peptide dose?

Select your peptide above for its recommended vial and water amounts, then use our dosage calculator for exact syringe units. Example: a 5 mg BPC-157 vial mixed with 2 mL water gives 2,500 mcg/mL, a 250 mcg dose equals 10 units on a U-100 syringe.

How much bacteriostatic water should I add?

It depends on the peptide and vial size. Each protocol above lists a recommended amount. Common ratios: 2 mL for 5 mg vials, 2 mL for 10 mg vials. More water = more dilute (easier to measure small doses); less water = more concentrated (smaller injections).

What supplies do I need for peptide injections?

The basics: your peptide vials, bacteriostatic water (30 mL vial), insulin syringes (U-100, 29-31 gauge), alcohol prep pads, and a sharps container.

Where do I inject peptides?

Most peptides are injected subcutaneously (under the skin) in the abdomen, thigh, or upper arm. The abdomen is preferred, consistent fat thickness and a large area for site rotation. Rotate sites at least 1 inch apart each injection.

What is the difference between mg, mcg, and syringe units?

1 mg = 1,000 mcg. Syringe units measure volume, not weight. On a U-100 insulin syringe, 100 units = 1 mL. The units you draw depend on your concentration.

Can I reuse insulin syringes?

No. Never reuse syringes. The needle dulls after a single use, increasing pain and infection risk. Use a fresh one every injection.
