Understanding Peptide Dosing

Research peptide dosing protocols vary significantly based on the specific compound, the intended area of study, route of administration, and individual factors like body weight. Most published research expresses doses in micrograms per kilogram (mcg/kg) to account for body mass differences across subjects.

Common administration frequencies range from multiple times daily (e.g., growth hormone secretagogues) to once weekly (e.g., long-acting GLP-1 agonists). The cycle duration — how long a protocol runs — also varies widely, from 4-week acute studies to 12+ week extended protocols.

This calculator helps convert between flat doses and weight-adjusted doses, plan administration frequency, and estimate the total supply needed for a given research cycle. All values are for informational purposes only and should not be interpreted as medical recommendations.

Frequently Asked Questions

Enter your desired dose per administration, frequency, body weight, vial size, and cycle duration. The calculator shows daily/weekly usage, weight-adjusted dose (mcg/kg), total peptide needed, and number of vials required. You can also select a peptide to auto-fill common research protocol presets.

Weight-adjusted dosing (mcg per kilogram of body weight) is the standard way research studies report doses. This allows for cross-study comparison and helps ensure doses are proportional to body size. The calculator converts your flat dose to mcg/kg for reference.

Enter your vial size and cycle duration. The calculator divides your total cycle requirement by the vial size and rounds up. For example, if your cycle needs 22.5 mg total and vials are 5 mg each, you need 5 vials (25 mg total, with some left over).
