Loading dose
Also called Loading phase, Front-loading, Load
A higher dose at the start of a course to reach a working level faster, followed by a lower maintenance dose.
In more detail
In pharmacology, a loading dose is most useful for drugs that leave the body slowly. Without one, it takes a long time for levels to build up on the maintenance dose alone.
In the peptide community the term shows up most with TB-500, where guides commonly describe a few weeks of higher doses before dropping to maintenance. Those schedules come from guides and forums, not from human trials.
Why it matters
A loading phase is the opposite of titration. Drugs with stomach side effects, like the GLP-1 class, start low on purpose. Do not apply loading logic to them.
Related terms
- TitrationStarting at a low dose and raising it in steps over weeks, so the body adapts and side effects stay manageable.
- Half-lifeThe time it takes for the amount of a substance in the blood to fall by half. It largely decides how often a compound is dosed.
- CycleA set period of taking a compound, usually followed by a planned break. A protocol might say 8 to 12 weeks on, 4 weeks off.
