Frequently asked questions
What is a peptide protocol?
A peptide protocol is a structured plan that specifies which peptides to use, how much to take, how often to dose, and for how long. Protocols often combine multiple peptides that work on complementary biological pathways—such as muscle repair, cognitive support, or metabolic regulation—to achieve a broader or more synergistic effect than a single compound alone.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL.
How much bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 2mL to a 5mg vial gives you a concentration of 2,500 mcg/mL, which is easy to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like precise signaling molecules in the body, binding to specific receptors and triggering targeted biological responses—such as stimulating growth hormone release, promoting tissue repair, or modulating immune activity.
