What is TB-500?
TB-500 is a peptide consisting of 43 amino acids. It is a synthetic version of the endogenous protein thymosin beta-4. that is encoded by the TMSB4X gene and is found in animal cells, both human and nonhuman.
Thymosin beta-4 promotes a variety of essential biological functions such as :
- Lowered inflammation
- Growth of new blood cells
- Increased production of immune cells
- Faster wound repair
Since thymosin beta-4 is naturally produced by the thymus gland in response to injury , researchers are actively investigating whether TB-500 accelerates the healing process in test subjects.
How does TB-500 work?
The main mechanism of action in TB-500 involves the upregulation of a cellular protein called “Actin”.
Actin plays a vital role in keeping the structural and functional integrity of cells intact, especially in muscle cells. This has led some researchers to hypothesize that TB-500 may increase the growth of new cells and hasten the healing of tissue injuries while improving muscle flexibility.
Due to the low molecular weight of TB-500, it is extremely mobile. Laboratory animal studies have shown that TB-500 can selectively upregulate Actin at the site of injury in laboratory animal models.
TB-500 in horse racing
Under Australia’s strict drug-free racing policy, anyone found guilty of injecting TB-500 into a racehorse would receive a minimum period of disqualification of two years:
“We have been aware of this substance for a number of years and we are confident we have the strategies and testing capabilities to control it.
“This drug has no place in racing, its use is easily detected in the thoroughbred and its administration to a racehorse would be viewed very seriously.”
TB-500 in athletics
While TB-500 is a research chemical with no recognized therapeutic use in humans, it has been banned by all major sporting organizations :
“Indeed, TB-500 packages have recently been confiscated by the Belgian Customs during a routine control.
The case has received worldwide attention from the media since it was connected to a professional athlete which was still employed by his team, who declared that the product was for personal use.
In another case, a former team doctor was arrested in possession of the substance.
There are very few scientifically validated reports of TB-500 use in humans, which began in the mid 1970s in settings of immunodeficiencies related to congenital athymia .
To date, the majority of studies involving TB-500 have been conducted in animal models and cell cultures. We will explore the documented effects of TB-500 in the following section.
Benefits of Thymosin Beta-4
Studies involving animal models and human research subjects have found that Thymosin Beta-4 produces several statistically significant effects. These effects are summarized below.
Thymosin Beta-4 may help repair heart muscles
An in vivo study involving heart cells found that Thymosin Beta-4 may be effective in healing heart injuries .
In particular, Thymosin Beta-4 was able to stimulate vessel growth while simultaneously preventing the death of heart cells.
One of the few clinical trials involving humans was actually able to corroborate this finding in patients following ST elevation myocardial infarction (STEMI).
Results of this small pilot study suggest that treatment with autologous thymosin β4 (Tβ4) prior to endothelial progenitor cell in STEMI patients may be associated with improved left ventricular function and exercise capacity at six months post-procedure.
This outcome requires follow-up before any conclusions can be drawn with respect to utilization of TB-500 or related compounds in settings of cell therapy for tissue repair .
Thymosin Beta-4 may accelerate healing from traumatic brain injury (TBI)
A 2012 paper reported rapid cognitive recovery in rats with traumatic brain injury (TBI) .
As early as six hours following injury, rats treated with Thymosin Beta-4 experienced functional recovery, and the creation of new brain cells and blood vessels took place as early as 24 hours post-injury.
Thymosin Beta-4 could be used to treat eye problems
As early as 2007, Thymosin Beta-4 was being examined as a potential clinical solution to repair eye damage .
Some of the applications speculated include:
- Diabetic eye disease
- Faster healing from cataract surgery
- Dry eyes
- Chemical injuries
A Phase II clinical trial involving human test subjects found Thymosin Beta-4 eye drops to be effective for treating severe dry eye .
In total, nine treated patients had significantly reduced discomfort and improved tear volume production, even 28 days following treatment.
Thymosin Beta-4 is useful for treating skin wounds that don’t heal
In preclinical animal studies involving various kinds of rats and mice (steroid-injected, old, diabetic), Thymosin Beta-4 was shown to be effective in healing skin wounds .
The same review also examined two Phase II clinical trials involving patients with ulcers.
Test subjects that received Thymosin Beta-4 experienced a healing process that was a month faster than those in the placebo group.
The authors also noted how Thymosin Beta-4 was able to inhibit further inflammation and infection.
So as an inflammatory agent, Thymosin Beta-4 shows great promise for future studies in test subjects.
Thymosin Beta-4 may treat joint inflammation
Even in animal studies, the science on this is not clear.
According to a 2017 review of Thymosin Beta-4 and rheumatoid arthritis, there are a handful of studies touting Thymosin Beta-4 exhibiting anti-inflammatory effects .
However, there were a fair number of reports saying Thymosin Beta-4 increases the secretion of pro-inflammatory compounds.
And while increased Thymosin Beta-4 expression is uniformly seen in the joint fluid of rheumatoid arthritis patients, it is uncertain whether this outcome is beneficial or harmful. This indicates that further research in this area may be warranted.
Thymosin Beta-4 could heal ligament injuries
A rat study involving the local administration of Thymosin Beta-4 discovered that Thymosin Beta-4 has “potential clinical use in repairing ligaments” .
After transecting the medial collateral ligament (MCL) in rats and treating rats with Thymosin Beta-4 a month, the treated rats had significantly better biomechanics function.
Moreover, the collagen fibers within the treated rats were uniform and evenly spaced out.
This implies that Thymosin Beta-4 heals wounds and injuries in a way where normal physical movement can be restored.
Let’s now turn our attention to TB-500 dosage and how researchers may calculate it in a research setting.

TB-500 Dosage Calculator and Guide
When it comes to choosing the TB-500 dosage for an experiment, there are a few things researchers need to know about.
Unlike some other peptides, there is no “standardized dose” for TB-500 and no “safe” or “recommended” level. That’s because the available clinical research on TB-500 is scarce and there are only a few human trials available to use as a reference.
Based on these trials, TB-500 has been applied in a wide range of doses, starting with as low as 0.5mcg/kg of bodyweight and reaching up to roughly 16,000mcg/kg of bodyweight (1260mg/day) for 10-14 days. No clinical trials include TB-500 cycles longer than 2 weeks [15, 16].
The following dosing protocol for healing with TB-500 is not supported by any studies published thus far, but it can serve as a starting point for researchers, who are advised to begin with still lower doses and titrate upward approaching this protocol:
- Daily Dose: 2mg, administered subcutaneously
- Frequency: Daily subcutaneous injections
- Study Duration: 15 days
- Notes: Researchers need three vials of TB-500 10mg to complete this protocol. Following the two week period, researchers may continue administering a maintenance dose of 1mg/daily, if necessary to achieve full or near-full recovery among test subjects.
TB-500 For Beginners
Researchers experimenting with TB-500 for the first time are recommended to adhere to the protocol mentioned above which involves daily doses of up to 2mg applied subcutaneously for 15 days.
TB-500 For Healing
TB-500 has shown potential in healing injuries within experimental animal models .
A number of rat studies have shown that Thymosin Beta-4 accelerates wound treatment . And some laboratory animal studies even put forth the idea of Thymosin Beta-4 offering rapid pain relief .
According to Kleinman et al., while TB-500 is “likely to have additional uses in the skin and in injured organs for tissue repair and regeneration” there is no research showing what dosage it may be administered to this end.
In fact, Thymosin Beta-4 has been tested topically in clinical trials regarding its potential for skin and corneal healing .
The peptide decreased median healing time of skin ulcers by 45% compared to placebo when applied topically as a 0.03% cream for three months .
When applied as 0.1% ophthalmic solution for up to 28-days, Thymosin Beta-4 was also effective in improving dry eye symptoms .
TB-500 For Muscle Growth
One purported effect of TB-500 is muscle growth.
Here’s a short list of some of the TB-500 effects observed in racehorses :
- Increased endurance
- Increased strength
- Increased muscle growth
- Improved flexibility of joints
- Improved muscle tone
These findings cannot be extrapolated to humans, suggesting that further research in this area is warranted.
Studies involving human test subjects have shown that TB-500 causes the up-regulation of Actin and promotes cell proliferation.
Although TB-500 is banned from sports, there is no evidence linking it to muscle growth in human test subjects .
However, the peptide may have potential beneficial effects on muscle recovery and healing, rather than muscle growth.
Clearly, further investigation is required in this area regarding TB-500’s effects on research subjects. Researchers interested in investigating this topic should adhere to the aforementioned recommendations of 2mg/daily, subcutaneously for 15 days.
If needed, TB-500 can be continued to be taken at 1mg/daily until achieving full recovery among test subjects.
TB-500 For Hair Growth
Findings from three laboratory animal studies involving rats and mice linked Thymosin Beta-4 to hair growth [24, 25, 26]. These claims have yet to be evaluated in humans and there is no research showing that it has this effect in test subjects.
While TB-500 has been shown to have many activities important in tissue protection, repair, and regeneration, there is currently no clinical research that has examined its use for hair growth.
