An oral capsule format
The peptides in this category are most often supplied as lyophilized powder for reconstitution. This listing supplies TB-500 as a pre-measured oral capsule instead — each capsule holds a fixed 500 mcg, so researchers can standardize per-capsule quantities without reconstitution, vials, or measuring. It is the same synthetic 43-amino-acid Thymosin Beta-4 sequence as the vial presentation; only the delivery format differs.

The research record
Malinda et al. reported a 41% increase in re-epithelialization within 4 days in full-thickness dermal wound models, concluding that “Tβ4 is a potent wound healing factor with multiple activities” (J Investigative Dermatology, 1999; PubMed 10469335).
Bock-Marquette et al. published findings in Nature showing enhanced cardiomyocyte migration and survival through integrin-linked kinase (ILK) and Akt signaling activation in myocardial infarction models (Nature, 2004; PubMed 15565145).
Philp et al. characterized angiogenesis and directional cell migration in both normal and aged rodent models through endothelial tube formation and ECM remodeling (Annals NYAS, 2004; PubMed 15037013).
Goldstein et al. reviewed NF-κB signaling modulation, pro-inflammatory cytokine reduction, and decreased inflammatory cell infiltration in tissue models (Expert Opinion on Biological Therapy, 2012; PubMed 22074294).
TB-500 vs BPC-157
Different mechanisms for different systems. TB-500 research centers on actin regulation, cell migration, blood vessel formation, and cardiac tissue. BPC-157 research centers on gastrointestinal integrity, connective tissue, and nitric oxide pathways. Published protocols regard them as complementary, not interchangeable. Heritage Labs USA carries both in capsule and vial formats.
Research applications
- Cell migration and wound closure assays
- Actin polymerization dynamics and G-actin/F-actin equilibrium
- Angiogenesis pathway screening
- ECM remodeling and collagen expression
- Inflammatory signaling profiling
- Cardiac cell survival and ILK activation
Frequently paired with
- TB-500 10mg — Same peptide, 10mg per vial for reconstitution.
- BPC-157 Capsules — Complementary connective-tissue research, same capsule format.
- GHK-Cu Capsules — ECM remodeling studies.
Storage
- Sealed capsules: Store in a cool, dry place away from light and moisture.
- Handling: Keep the bottle tightly closed; avoid heat and humidity.
- No reconstitution required.
