TB-500 Dosage: Real Numbers, Real Caveats
Dosing TB-500, and the human-evidence gap most sellers skip.
The quick version
- A soft-tissue repair peptide, usually stacked with BPC-157.
- The fragment people inject has almost no human trial data.
- Community loading: about 2 to 2.5 mg twice a week for 4 to 6 weeks.
What it is
TB-500 is a lab-made fragment of a natural healing protein called thymosin beta-4. People use it for soft-tissue and muscle repair, often alongside BPC-157. It is research-grade only and not FDA approved.
What the research shows
Here is the catch most sellers skip: almost all human research used full-length thymosin beta-4, not the TB-500 fragment people inject. Full-length versions have early human data in areas like dry eye and heart repair, but the fragment has no completed phase 2 or phase 3 trials for tendons, ligaments, or muscle. The animal injury data looks good; human proof for TB-500 itself is missing.
What it felt like
I have run TB-500 stacked with BPC-157 for a stubborn soft-tissue issue. The pair felt more useful than BPC alone for me, but I cannot cleanly separate the two, and that is the limit of an n of 1.
Dosing reality
A common loading pattern is around 2 to 2.5 mg twice a week for 4 to 6 weeks, then a lower maintenance dose. Because it is unapproved, these are community numbers with no label behind them.
The one mistake to avoid
The mistake is expecting TB-500 to fix what is really a training or movement problem. Peptides can support healing, but they do not replace rehab and smart loading.
Bottom line
TB-500 has decent animal data and fans who stack it with BPC-157, but the fragment has no real human trials. Go in with clear eyes.
Reminder: I am not a doctor and this is not medical advice. It is my own notes and reading of the research. Peptides sit in a legal grey area, research-grade is a real category, and it is on you to verify your own compliance. Talk to a qualified professional before you start anything, especially if you take other medication.
