Compounding pharmacies in United States can now prepare it · Oct 2026What this means ›
🇺🇸 United States · Compounding pharmacies may prepare it

Since October 2026, the FDA allows compounding pharmacies in United States to prepare it with a prescription: the step that followed its advisory committee's favourable vote. Next step: the FDA adding it permanently to its list of substances for compounding.

Our vial is research material (RUO), not a pharmacy preparation.

How it works

4 mechanisms. One peptide.

What this peptide does at the cellular level, in plain words.

Systemic, multi-zone recovery

Works body-wide, not just at one spot: useful when several areas need to recover at once.

Mobilizes reparative cells

Regulates actin and mobilizes reparative cells toward damaged tissue, supporting cell migration.

Antifibrosis · repair quality

Supports more organized repair, with less scar tissue.

Inflammation & immune modulation

Helps modulate the inflammatory and immune response during recovery.

Recommended stacks

Stacks. What to pair it with.

Peptides often synergize. These are the most studied combinations with this product, and what outcome they target.

The compound

Technical description.

TB-500 is the synthetic fragment of Thymosin Beta-4 (Tβ4), a protein found naturally in almost every human cell and tied to tissue repair. Its role is systemic: it regulates actin —the protein that orchestrates cell migration— and mobilizes reparative cells toward the damaged area. That is why it complements BPC-157, which repairs more locally: TB-500 works across several areas of the body at once.

SuperBio Labs TB-500 is supplied as lyophilized powder ≥99% pure, verified by HPLC and sequence-confirmed by LC-MS. Each batch ships with a third-party Certificate of Analysis covering identity, purity, peptide content, and endotoxin levels.

TB-500 research focuses on tissue repair, antifibrosis and inflammation modulation. Let's be honest about the level of evidence: by the injectable route the data are preclinical (animal models) — there are no clinical trials proving efficacy in humans by this route. Full-length Thymosin Beta-4 does have human data: as a gel it closed ulcers sooner in phase 2 (RGN-137), though not statistically significant and as eye drops it improved the cornea and dry eye (phase 3, RGN-259), although a 2025 European trial missed its endpoint. In models it also protects the heart after a heart attack. None of that equals proven injectable efficacy.

Safety. A tumor angiogenesis signal has been described: as a precaution, TB-500 is contraindicated in active cancer or with a prior cancer history. It is a controlled substance in sport (WADA S2). This is not medical advice; a product for research use only (RUO). If you have pre-existing medical conditions, consult a professional before using it.

Before you buy · from any store

How to choose where to buy peptides.

01
Per-batch, verifiable COA The certificate exists and can be checked — not "available on request".
→
02
HPLC purity + LC-MS identity How much is in the vial, and that it is the right peptide.
→
03
Endotoxins tested LAL test within range — not just purity.
→
04
2-8°C cold chain Documented end to end, not promised.
→
05
Traceability and support Lot number on the vial and someone who answers after.

This product meets all five — your batch COA ships with the kit.

Note

Combine with BPC-157 for complete recovery: TB-500 mobilizes systemically, BPC-157 repairs at the injury site.

When to use TB-500.

Injuries in several areas

Systemic action: no need to apply it nearby · complements BPC-157, which is more local.

Muscle tear

Muscle fiber and fascia · loading 2×/week, then maintenance.

Stiffness and scarring

Scar tissue and adhesions · antifibrotic effect in animal models.

Post-surgery

With BPC-157 in Wolverine to cover local and systemic repair.

Background inflammation

Cytokine modulation in animal models · background support during recovery.

Hair

Hair follicle via Tβ4 · preclinical signal, not a first choice.

Wounds that will not close

Ulcers and slow wounds: thymosin β4 gel closed them sooner in phase 2, not significant (full-protein data).

Honest side effects.

Well tolerated in animal models. Human data come from full-length thymosin β4 (topical and ocular); TB-500 itself has no published clinical trials.

Most reported: tiredness or drowsiness in the first days · heavy head · redness at the application site. It promotes cell migration and vessel formation: it is not used with active or recent cancer. Pregnancy and breastfeeding: no data. For athletes: thymosin β4 and its derivatives are on the WADA list (S2).
