Before you buy
What should you check before you buy TB-500?
Check that the certificate proves the batch is TB-500, not only that the sample is pure, and that it states the peptide actually measured in a vial. The released batch, lot TB5-260415-A, shows identity by LC-MS, 98.86% purity by HPLC against a not-less-than 95.0% release criterion, and 10.22 mg of net peptide in a 10mg vial.
- The right molecule. TB-500 is a fragment of the thymosin beta-4 protein rather than the full protein, and a source that presents the two as one and the same is worth a second look.
- Identity, not only purity. A purity figure says a sample is mostly one peptide; the LC-MS identity result is what says that peptide is TB-500.
- The rest of the panel. Titreon Analytical's certificate also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen, and its certificate number can be referenced with the laboratory.
- Your own batch. Vials ship unlabeled on purpose, so verification runs on your order number. Message us on WhatsApp with your order number and we will confirm your batch and send its published certificate. Then confirm that certificate with the laboratory that issued it.
The checks that apply to any seller are in how to verify peptide purity, and the full certificate for this batch is on the TB-500 certificate card.
The short answer
What is TB-500?
TB-500 is a synthetic peptide based on thymosin beta-4, an actin-binding protein the body uses in cell migration and tissue repair. In animal research, thymosin beta-4 accelerated dermal wound healing (Malinda et al., 1999) and, through its actin-binding site, drove angiogenesis, the growth of new blood vessels that feed recovering tissue (Philp et al., 2003), while a review describes it as a multi-functional regenerative peptide studied across skin, muscle, and heart (Goldstein et al., 2012). Its defining feature is that it is described as acting systemically rather than at one injection site, which is why studied protocols do not site administration near an injury and instead run an opening higher-frequency phase followed by a lower maintenance phase, reported here in units rather than mL. The evidence base is dominated by animal models: no controlled human trial establishes a dose or a healing outcome, so read every figure on this page as what a study measured, not a dose for any person.
The Science
Systemic Tissue Repair
TB-500 is a fragment of thymosin beta-4, a protein your body uses in cell migration and wound repair. Its defining feature is that it acts systemically, supporting recovery across the whole body rather than only at the injection site.
Cell Migration
Supports the movement of repair cells toward damaged tissue, a key early step in healing.
Angiogenesis
Promotes new blood vessel formation to improve nutrient delivery to recovering tissue.
Systemic Reach
The described action is systemic, which is why studied protocols do not site administration near an injury.
Applications
Common Use Cases
Chronic Soft-Tissue Injury
Persistent muscle and connective-tissue injury models in the published record.
Whole-Body Recovery
Systemic repair when multiple areas need attention at once.
Athletic Wear and Tear
Cumulative training-load injury is one of the studied research areas.
BPC-157 Stack
Paired with BPC-157 as the recovery duo for localized plus systemic repair.
Comparison
How does TB-500 compare with BPC-157?
TB-500 and BPC-157 are the two peptides most often discussed together for recovery, and they are studied for different things. BPC-157, a synthetic gastric pentadecapeptide, is studied largely for gut, tendon, and ligament repair and is commonly discussed as the local counterpart to TB-500. TB-500, a thymosin beta-4 fragment, is described as acting systemically across soft tissue and muscle (Goldstein et al., 2012).
| Peptide | Studied focus | Common framing in the recovery pair |
|---|---|---|
| TB-500 (thymosin beta-4 fragment) | Systemic soft-tissue, muscle, and connective-tissue repair | Described as acting systemically, not at one injection site |
| BPC-157 (gastric pentadecapeptide) | Gut, tendon, and ligament repair | Discussed as the local counterpart |
Because one is described as systemic and the other as local, the two are frequently combined as a recovery duo. That pairing has no published trial measuring the two together, so it remains a mechanistic argument rather than a measured outcome, and Peptara Labs does not design combinations for anyone. For a fuller breakdown, see the BPC-157 vs TB-500 comparison.
Healing evidence
What does the research show for healing and recovery?
The strongest TB-500 evidence is preclinical, built on its parent protein thymosin beta-4. In a rodent model, thymosin beta-4 accelerated dermal wound healing and increased cell migration into the wound (Malinda et al., 1999). In cardiac tissue it promoted cell migration, survival, and repair after injury (Bock-Marquette et al., 2004), and its actin-binding site was shown to drive angiogenesis, the new blood-vessel growth that supplies recovering tissue (Philp et al., 2003).
A broader review frames thymosin beta-4 as a multi-functional regenerative peptide studied across skin, muscle, cornea, and heart (Goldstein et al., 2012). What the record does not contain is a controlled human trial that fixes a healing result or a timeline, so these findings describe mechanisms and endpoints in models, not a schedule of what a person should expect. That is the most important thing to hold in mind before reading any figure, and any decision belongs with a licensed clinician.
Half-life
How long does TB-500 stay active?
Half-life is one of the most-asked TB-500 questions, and it is also where the public record is thinnest. The peptide is described as acting systemically rather than clearing from a single injection site, which is why studied protocols front-load an opening higher-frequency phase before dropping to a lower maintenance frequency rather than dosing locally and often.
We do not publish a single half-life number, because we cannot tie a specific figure to a verified controlled human study, and figures circulated elsewhere should be treated with caution. The practical point the research supports is the shape of the studied schedule, not a precise clearance time. For how the question is usually framed, see the TB-500 half-life page.

What it is
TB-500 is a synthetic fragment of thymosin beta-4, an actin-binding protein. The described mechanism is cell migration and tissue-repair signaling.
Systemic action
The published account is that it acts systemically rather than locally, which is why studied protocols do not site administration near an injury.
Published protocols
Published protocols describe an opening higher-frequency phase followed by a lower maintenance phase. The site reports those ranges and picks no schedule for anyone.
Evidence base
The record is dominated by animal models. No controlled human trial establishes a dose or an outcome, which is the most important thing to know before reading any figure.

three vials, all in good shape, seals tight, liquid clear. the one thing that bugged me was the delivery exception code that popped up in the tracking app. it said "held at facility" for a whole day and i thought something was wrong. turned out it was just a routing delay, nothing to do with the package itself. support called me to confirm, which was nice. otherwise the box was well packed, tray was new design with the little ridge. cold pack was frozen when i opened it. good.

Buying TB-500: FAQ
Where can I buy TB-500?
Peptara Labs sells TB-500 online as a 10mg research-grade vial, ordered from this page. TB-500 has no approved medicine, so it reaches the market only as research-grade material sold for laboratory research use, which makes the batch certificate the thing to compare between sources.
How much does TB-500 cost?
One 10mg vial is $220 USD, which is $22.00 per mg. Signing up by email takes 15 percent off a first order, which brings a vial to $187. Buying more of the same compound lowers the per-vial price on that line, to 40 percent off at 10 vials, which is $132 each.
Does Peptara Labs ship TB-500 to the US?
Yes. Orders to the United States, Canada, the United Kingdom and New Zealand ship tracked in 5 to 10 business days, guaranteed. Shipping is a flat $35, free over $250.
How do I verify the purity of TB-500 before I buy?
Read certificate COA-2026-2087 for the released batch, lot TB5-260415-A: 98.86 percent purity by HPLC, identity by LC-MS and 10.22 mg of net peptide in a 10mg vial, tested by Titreon Analytical, whose panel also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen. Vials ship unlabeled, so after delivery your order number on WhatsApp is what ties your vial to its batch certificate.
Does buying TB-500 with BPC-157 change the price?
Yes. A cart holding several different compounds earns a rate keyed to the total number of vials, so one TB-500 and one BPC-157 together take the 5 percent two-vial rate, $340.10 for the pair instead of $358. The Wolverine research kit holds BPC-157, TB-500, GHK-Cu and CJC-1295 / Ipamorelin for $462, 35 percent off their combined catalog price. The KLOW Combo blend puts TB-500, BPC-157, GHK-Cu and KPV in one 80mg vial for $210.
What comes with a TB-500 order?
One sealed 10mg vial of lyophilized TB-500 and bacteriostatic water to reconstitute it, plus a printed reference guide to what published studies reported. The batch certificate is published on the certificates page, because the vial itself ships unlabeled.
Is TB-500 approved for human use?
No. There is no approved TB-500 medicine anywhere, so it is sold only as research-grade material for laboratory research use, not for human use. Its evidence base is dominated by animal models, and no controlled human trial establishes a dose or an outcome.
TB-500 FAQ
What is TB-500 and how does it work?
TB-500 is a synthetic fragment of thymosin beta-4, a protein involved in cell migration and tissue repair. It is not thymosin alpha-1, a different thymus peptide studied in immune research. It is also sold with BPC-157 in one vial as the BPC-157 TB-500 blend. It is studied for its role in promoting healing across muscle, tendon, and other soft tissue by supporting cell movement to injury sites, new blood vessel formation, and reduced inflammation. Unlike a locally-acting peptide, it is described as systemic, meaning it works throughout the body rather than only at one injection site.
How is TB-500 different from BPC-157?
They are complementary, which is why they are so often stacked. BPC-157 is known for localized gut and tendon-ligament repair and is often dosed near the injury. TB-500 acts more systemically across soft tissue and muscle. Many people run both together as a recovery duo. See our BPC-157 vs TB-500 comparison for a full breakdown.
Is Peptara Labs a real company?
Yes. Peptara Labs is a registered business with responsive customer support via WhatsApp. Unlike anonymous Telegram sellers, we stand behind every order with our name, reputation, and ongoing support.
Are your peptides real?
Every TB-500 vial comes with a third-party Certificate of Analysis (COA) confirming 98%+ purity. We source from verified manufacturers and can provide lab documentation upon request. If you want to see a COA before ordering, message us on WhatsApp and we'll send it over.
Will the peptides survive shipping and heat?
Yes. Peptides ship in their lyophilized (freeze-dried powder) form, which is stable at room temperature for weeks. Fast, tracked delivery keeps transit short. Once reconstituted with bacteriostatic water, store the vial in your refrigerator. Storage instructions are included with every order.
How is it dosed?
Published protocols describe an opening higher-frequency phase split across two administrations per week, then a drop to a lower maintenance frequency. Because the described action is systemic, studied protocols do not site administration near an injury. What ships is a reference to those published ranges, in units rather than mL. This is not a prescription; consult a licensed clinician.
Can it be stacked with other peptides?
TB-500 and BPC-157 are frequently discussed together, because one is described as systemic and the other as local. That pairing has no published trial measuring the two in combination, so it is a mechanistic argument rather than a measured result. Peptara Labs does not design combinations for anyone.
What about side effects?
TB-500 is generally well tolerated. The most commonly reported effects are mild fatigue or a head-rush feeling shortly after dosing, and temporary irritation at the injection site. As a research compound it does not have large registered human trials, so we take a conservative approach to dosing and titration. Any dosing decision belongs with a licensed clinician, and we are available on WhatsApp for questions.
How is the 10mg vial reconstituted?
Reconstitution is arithmetic on concentration: the volume of bacteriostatic water against the 10mg in the vial. The reconstitution calculator on this site does that math and reports the result in units rather than mL. Storage instructions ship with every order. For anything medical, including how a compound is administered, speak with a licensed physician.
Is TB-500 the same as thymosin beta-4?
Not exactly. TB-500 is a synthetic peptide based on the active, actin-binding region of thymosin beta-4, the naturally occurring protein. The two names are often used interchangeably, but TB-500 is a fragment-based analog rather than the full native protein. A review describes thymosin beta-4 itself as a multi-functional regenerative peptide studied across skin, muscle, and heart (Goldstein et al., 2012).
How long until results appear in TB-500 research?
There is no controlled human trial that establishes a results timeline for TB-500. The evidence is preclinical: in animal models, its parent protein thymosin beta-4 accelerated wound healing and supported cell migration and new blood-vessel formation (Malinda et al., 1999; Philp et al., 2003). Those are mechanistic endpoints in models, not a schedule of what a person should expect, and any expectation belongs with a licensed clinician.
