Half-Life Decay Visualizer

Half-life is the time it takes for half of a peptide dose to be eliminated from the body. This determines dosing frequency — shorter half-lives require more frequent dosing. Visualize the exponential decay curve for any peptide below.

Decay Formula

C(t) = C₀ × 0.5^(t ÷ t_half)

After 5 half-lives, >97% of the peptide is eliminated from the body.
