TB-500: reconstitution and reference parameters (RUO)
> Updated:
Human schedule
Controlled data on this compound are limited. The regimens below were gathered from public sources online (studies and protocols) and are given as a reference, not a usage plan.
TB-500 (a thymosin beta-4 fragment) is reconstituted from lyophilized powder and given subcutaneously. The figures below are a generalized reference from community protocols; there is no controlled human trial of the fragment.
This is a concise reference to regimens described for adults; it is not an individual prescription.
TB-500 is positioned as a thymosin beta-4 fragment. The schedule in the table below follows the logic of frequent short administrations early in the course rather than one large dose.
| Period / condition | Dose | Escalation |
|---|---|---|
| Loading (4–6 weeks) | 4–5 mg per week, split into 2 injections | Starting phase |
| Maintenance (4–6 weeks) | 2–2.5 mg weekly | Reduced after loading |
| Spaced maintenance | 2–2.5 mg every other week | Minimum in this schedule |
Practical dosing and effect details
There are no controlled human trials of TB-500 itself (a thymosin beta-4 fragment), so the schedule in the table is compiled from community protocols and documented use rather than randomized trials.
The logic is straightforward: a loading phase (4–5 mg weekly, split into 2 injections over 4–6 weeks) sets a higher administration frequency at the start, after which the maintenance dose (2–2.5 mg) steps down first to weekly and then to every other week. In practice, the weekly total during maintenance is roughly half the loading-phase weekly total, and spaced maintenance halves it again while keeping the same single dose.
This shift from frequent to less frequent administration is typical of research peptide protocols, where the goal is to first reach a stable level of exposure and then sustain it with fewer injections. These figures are a generalized reference to regimens described in the literature and community sources, not a clinical recommendation and not instructions for self-administration.
