\*\*Recovery & Repair · Moderate Evidence · Research Only\*\* ### TB-500 Oral Capsule Oral TB-500 for convenient systemic healing and recovery support. ### Description Oral TB-500 capsules provide systemic healing support through intestinal absorption. TB-500 is a synthetic analog of the active region of Thymosin Beta-4 (TB4), a ubiquitous actin-sequestering protein found in virtually all nucleated human cells. Thymosin Beta-4 is one of the most abundant intracellular peptides in the body, playing a critical role in cell migration, wound healing, and tissue repair. TB-500 corresponds to the LKKTET actin-binding domain of TB4 and retains its key biological activities including actin regulation, anti-inflammatory effects, and angiogenesis promotion. Injectable TB-500 has been extensively studied for cardiac repair, wound healing, and musculoskeletal recovery, with particularly compelling data in cardiac regeneration models. While injectable forms have higher bioavailability for acute musculoskeletal injuries, oral TB-500 provides convenient systemic actin regulation and healing support for general recovery maintenance, inflammation reduction, and as a complement to injectable protocols. ### Key Characteristics - \*\*Half-Life:\*\* Varies - \*\*Administration Routes:\*\* Oral capsule - \*\*Typical Dose:\*\* One capsule (per prescriber guidance) - \*\*Frequency:\*\* Daily or every other day ### Investigated Benefits - Systemic healing support - Reduced inflammation - Improved flexibility - Convenient oral administration \\\* Benefits based on preclinical/animal research unless otherwise noted. ### Mechanism of Action “Oral TB-500 for convenient systemic healing and recovery support.” TB-500 sequesters G-actin (globular actin monomers) through its LKKTET domain, regulating the dynamic equilibrium between G-actin and F-actin (filamentous actin). This actin regulation is fundamental to cell migration — cells cannot move without coordinated actin polymerization and depolymerization at the leading and trailing edges. By modulating actin dynamics, TB-500 facilitates the migration of repair cells (fibroblasts, endothelial cells, myoblasts) to sites of tissue damage. TB-500 also upregulates matrix metalloproteinases (MMPs) that break down damaged extracellular matrix to allow tissue remodeling, promotes angiogenesis through VEGF and laminin-5 signaling, and has anti-inflammatory effects through downregulation of NF-kB and pro-inflammatory cytokines. Oral absorption provides systemic distribution of these effects, supporting healing and recovery throughout the body. ### Dosing Protocol - \*\*Typical Dose:\*\* One capsule (per prescriber guidance) - \*\*Frequency:\*\* Daily or every other day - \*\*Cycle Length:\*\* 4–8 weeks - \*\*Administration:\*\* Oral capsule \*\*Protocol Notes:\*\* Take on empty stomach. For acute injuries, injectable forms are preferred. Oral form is convenient for maintenance and general recovery. ### Storage Information Store at room temperature, away from light and moisture. ### Quality & Sourcing Standards When sourcing TB-500 (Capsule) for research purposes, the following quality benchmarks should be verified before use. - \*\*Purity:\*\* \>98% (verified by HPLC) - \*\*Certificate of Analysis (COA):\*\* Must be provided by supplier - \*\*Endotoxin Testing:\*\* \<0.1 EU/mg (prevents bacterial contamination) - \*\*GMP Compliance:\*\* Manufactured in cGMP-certified facility - \*\*Third-Party Testing:\*\* Independent lab verification preferred ### Research Highlights 1. Injectable form demonstrated cardiac repair and wound healing 2. Oral bioavailability demonstrated in pharmacokinetic studies 3. Systemic healing effects well-documented for injectable form ### Evidence Level \*\*Moderate Evidence\*\* Multiple animal studies and/or early human trials. Reasonable confidence in mechanism, but human data is limited. Animal & In-Vitro Only — Mechanism observed in cell culture or animal models. No human efficacy data. Not evidence of an effect in humans. ### Compatible Peptides Peptides commonly used alongside TB-500 (Capsule) for synergistic effects. - \*\*BPC-157 (Capsule)\*\* (Recovery & Repair): Oral BPC-157 for gastrointestinal healing, gut permeability, and systemic anti-inflammatory effects. - \*\*BPC-157 + TB-500 (Capsule)\*\* (Blends & Combos): The Wolverine Stack in oral capsule form for convenient systemic recovery support. ### Quick Reference - \*\*Category:\*\* Recovery & Repair - \*\*Status:\*\* Research Only - \*\*Dose:\*\* One capsule (per prescriber guidance) - \*\*Frequency:\*\* Daily or every other day - \*\*Cycle:\*\* 4–8 weeks ### FDA Disclaimer The statements made within this website have not been evaluated by the US Food and Drug Administration.
