Frequently asked questions
How do I calculate my peptide dose?
Select your peptide above. The tool calculates your exact syringe units based on vial size and bacteriostatic water volume. For example, a 5 mg BPC-157 vial mixed with 2 mL water gives you 2,500 mcg/mL — a 250 mcg dose equals 10 units on a U-100 syringe.
How much bacteriostatic water should I add to my peptide?
It depends on the peptide and vial size. Our tool pre-fills the recommended amount for each compound. Common ratios: 2 mL for 5 mg vials, 2 mL for 10 mg vials. More water = more dilute solution (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 gauge), alcohol prep pads, and a sharps container. Select your peptide above for exact quantities based on your protocol length.
Where do I inject peptides?
Most peptides are injected subcutaneously (under the skin) in the abdomen, thigh, or upper arm. The abdomen is preferred — it has 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 (micrograms). Syringe units measure volume, not weight. On a U-100 insulin syringe, 100 units = 1 mL. The number of units you draw depends on your concentration (how much peptide per mL of liquid).
Can I reuse insulin syringes?
No. Never reuse syringes. The needle dulls after a single use, increasing pain and infection risk. Syringes are inexpensive — use a fresh one for every injection.
