This is the most comprehensive peptide dosage reference for Indian researchers in 2026. The table below covers all 18 peptides available from Peptide Central — research dose, half-life, frequency, route, and typical syringe draw (assuming a 10 mg vial reconstituted with 2 ml bacteriostatic water, giving 5 mcg/IU or 5 mg/ml as applicable). For any vial size or BAC water volume, use the free BAC Water Reconstitution Calculator to get exact IU draws instantly.
Important note: All doses listed are research reference values from published literature. These peptides are for in-vitro and laboratory research use only. Not for human consumption.
How to Use This Table
The "Typical Draw (IU)" column assumes a 10 mg vial + 2 ml BAC water (concentration = 5,000 mcg/ml = 50 mcg/IU on a U-100 insulin syringe). If you reconstitute differently — for example 1 ml BAC water giving 100 mcg/IU — divide the listed IU value by 2. The BAC Water Calculator handles all these calculations automatically for any configuration.

*Typical draw assumes 10 mg vial + 2 ml BAC water (50 mcg/IU). Use the BAC Calculator for any other configuration. SC = subcutaneous, IM = intramuscular, IN = intranasal, IV = intravenous, EOD = every other day.
Reading the IU Scale
All research peptide dosing uses standard U-100 insulin syringes where 1 IU = 0.01 ml. The number you draw to on the syringe barrel (e.g., "10 IU") equals 0.1 ml. Concentration (mcg/IU) depends entirely on how much BAC water you added. This is why the BAC Water Reconstitution Calculator is the most important tool for any peptide researcher — enter your vial size and BAC water volume once, get concentration and IU draw for any dose instantly.
Half-Life and Dosing Frequency
Half-life determines how often a peptide needs to be administered to maintain research-relevant tissue exposure. Short half-life peptides like Semax (10–20 min intranasal) require twice-daily administration for sustained effect. Weekly GLP-1 agonists like Retatrutide achieve steady state after 4–5 doses. Epitalon's short plasma half-life (30–60 min) does not limit its biological efficacy — its epigenetic and telomerase effects are cell-autonomous and persist well beyond plasma clearance, which is why 10–20 day pulse cycles are the standard protocol.
Route of Administration Notes
Subcutaneous (SC) injection into the abdominal fat layer is the most common route for most peptides. Rotate sites to prevent local tissue reactions. Intramuscular (IM) dosing is used for BPC-157 and TB-500 when targeting a specific muscle group. Intranasal routes (Semax, Selank, Pinealon) deliver peptides directly to the olfactory neuroepithelium, enabling rapid CNS exposure that bypasses blood-brain barrier limitations.
