TB-500
TB-500. A synthetic fragment of Thymosin Beta-4, the body's native repair signal. 43 amino acids that tell damaged tissue to rebuild, not just recover.
Clinician-prescribed. Ships from a licensed U.S. pharmacy.
Rebuild. Not Just Recover.
Standard anti-inflammatory interventions suppress the pain signal. TB-500 addresses the structural damage. Its LKKTETQ actin-binding domain directs repair cells to injury sites, builds new vasculature to deliver oxygen and nutrients, and suppresses the NF-kB inflammatory cascade that keeps tissue stuck in a damage loop. At 4.9 kDa, TB-500 reaches injured tissue with a diffusion profile that larger growth factors cannot match. It operates intracellularly through cytoskeletal regulation and ILK signaling rather than through extracellular receptor binding, giving it regenerative reach across multiple tissue types simultaneously.
The Evidence
Conventional Recovery vs. TB-500 (Thymosin Beta-4 Analog)
| Conventional Recovery | TB-500 (Thymosin Beta-4 Analog) |
|---|---|
| NSAIDs suppress pain signal without addressing structural damage | Directs repair cells to injury site through LKKTETQ-driven migration |
| Corticosteroids reduce inflammation at the cost of tissue integrity | Suppresses NF-kB inflammation while promoting organized tissue rebuilding |
| PRP provides growth factor bolus without directing cell migration | Builds new vasculature at injury sites via angiogenic signaling |
| Rest alone relies on the body's baseline repair capacity | Active repair acceleration, not passive waiting for baseline healing |
| Prolotherapy creates irritation without constructive signaling | Anti-fibrotic domain reduces scar tissue, promotes functional architecture |
| Each approach treats one symptom rather than the repair deficit | Three active domains operating in parallel: migration, anti-inflammation, survival |

Important Information About Compounded Injectables
- Compounded medications are not reviewed or approved by the FDA and do not undergo the same pre-market evaluation as FDA-approved drugs.
- IVUSE peptide injections are prepared using peptide ingredients by FDA-registered, U.S.-licensed 503A & 503B compounding pharmacies, where available and clinically appropriate.
- Availability and formulation may vary based on state regulations, evolving clinical guidance, and pharmacy partners.
All prescriptions, treatment decisions, and care plans are made independently by licensed healthcare providers using their professional judgment. Images and product depictions are for illustration only; actual packaging and supplies may vary.
*If you are interested in a prescription product, IVUSE will coordinate a telehealth visit with a licensed medical provider who will determine whether you are an appropriate candidate based on your health profile and current standards of care. If approved, a prescription will be issued and filled by one of our partner pharmacies. All prescriptions are subject to provider discretion and clinical appropriateness.
These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. All information provided here is for educational purposes only and does not replace personalized medical advice from a qualified healthcare professional.
Stop the medication and contact your provider if you experience persistent or concerning symptoms. Seek immediate medical care if you develop signs of a severe allergic reaction (such as hives, facial swelling, or difficulty breathing) or any rapidly worsening symptom.

BPC-157
Faster injury healing, joint support, and gut repair. BPC-157 stabilizes the repair site and protects the GI tract while TB-500 drives cellular migration and collagen synthesis across soft tissue.
Ipamorelin
Adds GH elevation for muscle growth, fat reduction, and faster tissue repair. Ipamorelin increases the anabolic signal and TB-500 accelerates the structural repair that follows.
GHK-CU
Skin healing and collagen production for visible recovery. GHK-CU rebuilds the extracellular matrix at the surface while TB-500 repairs the deeper soft-tissue layers.
