How do I calculate peptide dosing?
Peptide dosing is typically calculated based on body weight, using micrograms per kilogram (mcg/kg) as the standard unit. First, convert your body weight to kilograms if needed (divide pounds by 2.205). Then multiply your weight in kg by the recommended mcg/kg dose for your specific compound. Most peptides have established low, standard, and high dose ranges based on published research. Always start at the lower end of the dosing range and titrate upward based on response and tolerability.
What syringe sizes are used for peptide injections?
Insulin syringes are the standard choice for subcutaneous peptide injections. The most commonly used sizes are 0.5 mL (50 units) and 1 mL (100 units) with 29-31 gauge needles. The 0.5 mL syringe offers finer graduation marks for more precise small-volume doses, making it ideal for most peptide protocols. For intramuscular injections, larger gauge needles (25-27G) with 1-3 mL syringes may be required depending on the compound and injection site.
How do I convert mg to mcg for peptide dosing?
To convert milligrams (mg) to micrograms (mcg), multiply by 1,000. For example, 0.25 mg equals 250 mcg, and 1 mg equals 1,000 mcg. This conversion is critical in peptide dosing because most research protocols express doses in mcg, while peptide vials are often labeled in mg. A common source of error is confusing mg and mcg, which can result in a 1,000-fold dosing mistake. Always double-check your units before calculating syringe volumes.
