How Long Does Thymosin Alpha-1 Last? Half-Life & Dosing Frequency
Thymosin Alpha-1 has a reported half-life of ~2 hours. This page explains what that means for how long Thymosin Alpha-1 stays active, how quickly it clears the body, and how often it is dosed in research.
What Is Thymosin Alpha-1's Half-Life?
The half-life of a compound is the time it takes for the amount in the body to fall to half its original level. For Thymosin Alpha-1, research reports a half-life of ~2 hours. A thymic peptide that modulates immune function and enhances vaccine response.
How Long Does Thymosin Alpha-1 Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of ~2 hours, Thymosin Alpha-1 is largely cleared after roughly 10 hours. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use Thymosin Alpha-1 2-3x per week (Any time of day). Dosing frequency is generally matched to the half-life and to how long the compound's effects last — peptides with shorter half-lives are often dosed more frequently, while longer-acting compounds may be dosed less often.
Frequently Asked Questions
What is Thymosin Alpha-1's half-life?
In the research literature, Thymosin Alpha-1 is reported to have a half-life of ~2 hours. Half-life is the time it takes for the amount of a compound in the body to fall to half of its original level.
How long does Thymosin Alpha-1 stay in your system?
As a general pharmacokinetic rule, a compound is mostly cleared after about five half-lives. For Thymosin Alpha-1, with a half-life of ~2 hours, that works out to roughly 10 hours. Individual metabolism, dose, and dosing frequency can shift this.
How often is Thymosin Alpha-1 dosed?
Research protocols commonly use Thymosin Alpha-1 2-3x per week. Dosing frequency is generally matched to the compound's half-life and to how long its effects last.
