Loading Dose
Also known as: loading phase · front-load
A larger initial amount used to reach a target level quickly, before settling to a smaller maintenance amount.
A loading phase uses a larger amount at the start of a protocol to build the compound up to a working level faster than a steady amount would, after which a smaller maintenance amount holds it there.
The concept appears in research protocols for compounds with a slow build-up, such as some tissue-repair peptides. It is reference terminology only — not dosing advice — and all compounds are supplied for research purposes only.

Maintenance Dose
The smaller ongoing amount that holds a compound at a target level after any initial loading phase.
Titration
Gradually adjusting an amount — usually starting low and increasing — to find a suitable level in a research protocol.
Cycle (Research Protocol)
A defined period of administration followed by a break — the on/off structure many research protocols follow.
Half-Life
The time for a compound’s concentration to fall by half — a key determinant of dosing frequency in research.
Research Use Only (RUO)
A designation that a compound is supplied strictly for laboratory research and is not intended for human or veterinary use.
