Amounts are shown as each source reports them. Where sources disagree, the table lists each one; there is no single agreed amount.
Published human trials
No human-trial evidence found in the PeptideWhiz study library for TB-500. The amounts above come from practitioner protocols and Dr. Trevor reports only, so the evidence level is low. See the TB-500 research overview for the studies we index.
FAQ
What TB-500 dosage is reported in research?
Reported in research: 2–5 mg once or twice weekly in most practitioner protocols (one source lists 500–1,000 mcg daily), and 2.5 mg twice weekly to 5 mg every five days in Dr. Trevor reports. No human-trial dose is reported in our study library. Sources vary.
Is there human-trial evidence for TB-500 dosing?
No. No human-trial evidence found in the PeptideWhiz study library for TB-500; the amounts listed come from practitioner protocols and Dr. Trevor reports.
Why do the reported TB-500 amounts differ?
Each source studied or described a different group, form, goal and time frame, so reported amounts vary between sources. PeptideWhiz lists each one with its source type instead of picking a single amount.
Where can I convert a TB-500 amount into syringe units?
The PeptideWhiz calculator for TB-500 converts a vial amount, water volume and target amount into mL and syringe units. It does not suggest an amount.
