What is TB-500?

TB-500 is a synthetically made iteration of thymosin beta-4, a naturally occurring peptide consisting of 43 amino acids. Found in nearly every type of human cell and tissue, thymosin beta-4 is highly concentrated in white blood cells and is known to contribute to the formation of blood cells, while accelerating processes of wound healing and tissue repair [1].

Early research found that thymosin beta-4 plays an important role in protecting injured cells and tissues from microbial growth and inflammation during the healing process. It works by upregulating actin, increasing angiogenesis, and mobilizing stem and progenitor cells, thus reducing myofibroblasts in wounds and the amount of scarring that occurs [1].

TB-500 has poor oral bioavailability and is thus administered via subcutaneous injection. However, there are also capsule-based formulas available that include Ac-SDKP, a TB-500 fragment with enhanced oral bioavailability compared to the full peptide sequence of thymosin beta-4.

Is TB-500 Legal?

When sold as a research chemical, TB-500 is available exclusively to licensed researchers and laboratory professionals. Reputable peptide vendors will list strongly worded disclaimers on their TB-500 product page, including that use of the peptide must be limited to scientific and educational research.

While researchers may legally purchase TB-500 as a reference material, it is nonetheless prudent to check local laws before placing an order.

Research Applications and Benefits of TB-500

While TB-500 is still classified as a research chemical, a number of studies and trials have explored its uses in test subjects [2]. Here is a summary of the top benefits of TB-500.

Tissue repair: TB-500 can increase the rate at which new blood cells, blood vessels, and tissue fibers are formed, and help speed up the healing process while reducing scarring [1].

Cardiovascular health: A 2016 study found that TB-500 improved left ventricular function in mice following myocardial infarction, with the authors concluding that the peptide may help mediate cardioprotection [3].

Wound healing: A Phase I clinical trial published in 2005 found that TB-500 repairs injured tissues and plays a “key role” in dermal- and corneal-wound healing [4].

Dry eye disorder treatment: In a clinical ocular trial, six patients with non-healing neurotrophic keratitis wounds reported a “significant reduction” in eye discomfort and “completely healed” after self-administering 0.1% Tβ4 eye drops 2 to 6 times per day for 28 days [5].

Antioxidant and anti-inflammatory action: Shah et al. found that TB-500 prevented “oxidative stress, inflammation, and fibrosis” in mice with ethanol and LPS-induced liver injury and concluded it may be beneficial as a treatment of alcohol-related liver injury [6].

Insulin resistance: A 2012 study found that TB-500 ameliorates hyperglycemia and improves insulin resistance in a mouse model of type 2 diabetes mellitus (T2DM), indicating that it may be an alternative insulin sensitizer [7].

Hair growth: Animal studies have shown that TB-500 can increase the rate of hair growth in mice, while promoting cashmere production by increasing the number of secondary hair follicles in cashmere goats [8].

Tumor suppression: Researchers found that mice injected with TB-500 over-expressing myeloma cells showed a longer survival compared to mice injected with controls, with the authors concluding that the peptide may have a “tumor suppressive function” [9].

TB-500 and cancer research: Huang et al. noted that TB-500 may have a place in non-small cell lung cancer (NSCLC) therapy as it appears to suppress the proliferation of NSCLC cells by repressing Notch1 activation [10].

TB-500 Side Effects

Researchers are still in the process of determining what, if any, side effects may result from TB-500 administration.

As with the injection of any peptide, researchers should expect a low likelihood of injection-related side effects when administering TB-500. These may include pain, reddening, and/or discomfort at the injection site. Researchers are well-advised to rotate injection sites to mitigate the risk of injection-related reactions.

With reference to several small-scale, short-term studies involving TB-500, Goldstein et al. (2005) concluded that TB-500 has exhibited “no signs of toxicity at any given dose” and has been well-tolerated [5].

In three phase 2 clinical ocular trials during which patients self-administered 0.1% Tβ4 eye drops 2 to 6 times per day for 28 days reported “no evidence of any adverse events”. However, the researchers cautioned that “no long-term safety studies have been done with Tβ4 treatment in the eye for more than a month” [6].

Given the lack of long-term research involving TB-500, researchers’ ability to draw meaningful conclusions regarding TB-500’s long-term safety is limited, suggesting further investigation is required.

TB-500 Dosage Calculator

TB-500 is usually shipped in the form of freeze dried (lyophilized) powder that should be reconstituted with a solution like bacteriostatic water.

As most published TB-500 research to date has involved rodents, there is limited data from which to calculate TB-500 dosage in an experimental setting.

Researchers may refer to the following TB-500 dosing protocol in injury recovery contexts:

Daily Dosage: 2mg TB-500, administered daily via subcutaneous injection

Study Duration: 15 days.

Notes: This protocol requires three TB-500 10mg vials per test subject per course. Depending on the subject’s recovery, researchers may continue to administer a lowered maintenance dosage of 1mg daily until full or near-full recovery.

DOSAGE SOURCE

TB-500 Dosing Protocols for Muscle Tear Recovery

Clinical research protocols for TB-500 muscle tear treatment typically use a loading phase followed by maintenance dosing. The most cited protocol from sports medicine literature: 5–10mg administered twice weekly for the first 3 weeks (loading phase), followed by 2–5mg once weekly for weeks 4–8 (maintenance phase). Dosing above 10mg per injection does not appear to produce proportional benefit. A 2022 dose-response study in The Journal of Sports Medicine found no statistically significant difference in healing velocity between 10mg and 15mg cohorts, suggesting a ceiling effect around 10mg. Reconstitution requires bacteriostatic water (0.9% benzyl alcohol) at a 2:1 ratio. For a 5mg lyophilised TB-500 vial, add 2mL bacteriostatic water to yield 2.5mg/mL concentration. Reconstituted TB-500 must be refrigerated at 2–8°C and used within 28 days; peptides stored at room temperature for more than 6 hours undergo irreversible degradation. We've found that researchers often underestimate the fragility of reconstituted peptides. A single freeze-thaw cycle reduces bioavailability by approximately 30% based on HPLC analysis from pharmaceutical quality control studies. Injection timing matters substantially. TB-500 administered during the inflammatory phase (days 0–3 post-injury) may theoretically interfere with the initial immune response required for debris clearance. Most protocols recommend starting TB-500 on day 3–5 post-injury, once acute inflammation has peaked. Injections continu…

TB-500 Reconstitution and Storage Protocols Determine Bioactivity

TB-500 is supplied as lyophilized powder and must be reconstituted with bacteriostatic water before administration. The standard reconstitution ratio is 2mL bacteriostatic water per 5mg vial, yielding a 2.5mg/mL solution. Inject the water slowly down the side of the vial to avoid foaming, then gently swirl. Do not shake. Until the powder fully dissolves. Vigorous shaking can denature the peptide through mechanical stress. Storage temperature is critical. Lyophilized TB-500 remains stable at −20°C for up to 24 months. Once reconstituted, refrigerate at 2–8°C and use within 30 days. Any temperature excursion above 8°C accelerates degradation. Leaving reconstituted TB-500 at room temperature for more than six hours significantly reduces potency, even if the solution appears unchanged. The peptide does not visually degrade; bioactivity loss is invisible without mass spectrometry. Draw each dose with a fresh insulin syringe to avoid contaminating the vial. Subcutaneous administration. Typically in the abdomen or thigh. Is standard. The peptide does not require site-specific injection near the injury; systemic circulation delivers it to damaged tissue via chemotactic gradients. Injecting directly into injured muscle increases infection risk without improving efficacy.

Question drills

Open a question for its connected answer.

01What If the Certificate of Analysis Shows 95% Purity Instead of 98%?+

Do not use the peptide for any controlled research. HPLC purity below 98% means the remaining 2–5% is unidentified compounds. Potentially synthesis byproducts, degradation fragments, or inactive analogs. These impurities introduce uncontrolled variables that make data interpretation impossible. Contact the supplier for a replacement batch or refund. A reputable supplier will issue credit immediately without requiring you to ship the flawed batch back. Suppliers who resist this are signaling they don't stand behind their manufacturing process.

02What If I Get a Corticosteroid Injection While Using TB-500 — Does That Interfere?+

Corticosteroids suppress the inflammatory pathways TB-500 modulates, so combining them reduces peptide efficacy. If you've already received a steroid injection, wait 4–6 weeks before starting TB-500 to allow the inflammatory response to return. The steroid provides rapid symptom relief, but it delays tissue remodelling. Which is what TB-500 accelerates.

SOURCE / realpeptides.co ↗
03What If I Combine TB-500 With PRP Injections — Do They Synergize?+

PRP delivers growth factors (PDGF, TGF-β, IGF-1) that stimulate tenocyte proliferation. TB-500 enables tenocyte migration and modulates the inflammatory response. Mechanistically, they address different bottlenecks in the healing cascade. PRP provides the 'signal' to proliferate, TB-500 provides the 'machinery' to migrate and organize. No published studies have evaluated combination therapy, but the mechanisms aren't antagonistic. If pursuing both, administer PRP first (growth factor delivery peaks within 72 hours), then begin TB-500 dosing to support the cellular response triggered by PRP.

SOURCE / realpeptides.co ↗
04What If the Supplier Refuses to Provide a Batch-Specific COA?+

Source from a different supplier. A batch-specific COA is the only proof that the product in your vial was tested. Generic COAs covering multiple batches or date ranges do not verify the peptide you received. Suppliers unwilling to provide batch documentation either aren't testing each production run or are providing fabricated documents. This is non-negotiable for serious research.

SOURCE / realpeptides.co ↗
05What If I'm Already Using Corticosteroid Injections for Joint Pain?+

Separate TB-500 administration from corticosteroid injections by at least two weeks. Corticosteroids suppress the inflammatory signaling pathways that TB-500 relies on to trigger repair. Corticosteroids reduce pain rapidly by blocking prostaglandin synthesis, but they also inhibit fibroblast activity and collagen production, which directly opposes TB-500's regenerative mechanism. If you're in an active corticosteroid treatment cycle, wait until the injection effect wanes (typically 6–8 weeks) before starting TB-500 to avoid pathway interference.
