About hCG
hCG is listed in PeptideGraph's compound database with an approximate half-life of ~33 hours (33 hours). It is commonly researched in the context of testicular function / fertility. Use the Half-Life Tracker to model plasma concentration over time, or the Dose Calculator to convert vial concentration into syringe units after reconstitution with bacteriostatic water.
Values are approximate educational estimates compiled for research tooling — not clinical dosing guidance. See the research disclaimer.
Frequently asked questions
What is the half-life of hCG?
hCG has an approximate biological half-life of ~33 hours (33 hours). Use PeptideGraph’s Half-Life Tracker to visualize its plasma concentration curve over time.
What is hCG used for in research?
hCG is commonly researched for testicular function / fertility. PeptideGraph provides free tools to calculate reconstitution doses and model pharmacokinetic decay for educational purposes.
How do I calculate a hCG dose?
Use PeptideGraph’s Dose Calculator: enter your vial amount, bacteriostatic water volume, and desired dose to get the exact syringe unit mark and injection volume in mL for hCG or any reconstituted peptide.
How long does hCG stay in your system?
As a rule of thumb, a compound is largely cleared after about 4–5 half-lives. For hCG (half-life ~~33 hours), that is roughly 165 hours. Exact clearance varies; this is an educational estimate only.
