How to Store and Handle
Store the sealed vial at -20C for long-term preservation. Short-term storage of two weeks or less is acceptable at 2-8C. The lyophilized product can withstand room temperature during transit but must be refrigerated or frozen once it arrives.
To reconstitute, use an insulin syringe to inject bacteriostatic water slowly along the inner wall of the vial. Do not shake. Let the powder dissolve passively without agitation. Clean the rubber stopper with an alcohol pad before every draw. Store the reconstituted solution at 2-8C and use within 28 days. Do not refreeze. If pairing with BPC-157, reconstitute each peptide in its own vial to maintain independent concentration control.
Real Peptides TB-500 10mg (Thymosin Beta-4) is a research-grade lyophilized peptide priced at $48.00 per vial (sale price, regular $96.00), which works out to $4.80/mg. Each lot comes with a published Certificate of Analysis confirming HPLC purity of 99% or higher and endotoxin screening below 0.1 EU/mg. The product is in stock and ships from US inventory within 24 hours. We reviewed the listing, checked the published documentation, and scored it against our four editorial criteria.
Real Peptides TB-500 10mg Overview
TB-500 is a synthetic version of Thymosin Beta-4, a 43-amino-acid peptide involved in cell migration, actin binding, and tissue repair. Preclinical research has studied TB-500 for wound healing, cardiac repair, and anti-inflammatory effects in animal models. Human clinical evidence remains sparse. Real Peptides finishes the product in the United States under SKU RP-TB5010V with lot-specific analytical documentation.
The published COA is the defining feature of this product. Real Peptides provides HPLC verification showing purity at 99% or above and endotoxin results under 0.1 EU/mg. This documentation standard exceeds what most peptide vendors offer. For context on how TB-500 and BPC-157 compare at a molecular and functional level, see our BPC-157 vs TB-500 comparison.
Our Verdict
Real Peptides TB-500 10mg receives 4.2 out of 5 from our editorial team. Sub-scores: Testing 5.0, Purity 5.0, Labeling 4.5, Value 3.0. Testing and purity scores reflect the published COA with HPLC verification and endotoxin screening. The value score of 3.0 accounts for the $48.00 price point, which is higher than budget TB-500 options on the market.
The strengths of this product are clear: verified purity, published lot COA, endotoxin data, and consistent availability. At $4.80/mg it is actually cheaper per milligram than PeptideGod TB500, making the documented option both more transparent and more cost-effective at this vial size. Researchers building a BPC-157 and TB-500 stack with verified components should pair this with Real Peptides BPC-157 when it returns to stock. We also recommend purchasing bacteriostatic water from the same vendor at $4.80 per 10ml vial for reconstitution.

FAQ - Real Peptides TB-500
Is TB-500 the same as Thymosin Beta-4?
TB-500 is a synthetic peptide based on the full Thymosin Beta-4 protein sequence. The two terms are used interchangeably in the research peptide market, though some vendors distinguish between the full-length protein and synthetic fragments. Real Peptides labels this product as TB-500 (Thymosin Beta-4).
Does Real Peptides publish a COA for TB-500?
Yes. Each lot ships with a Certificate of Analysis showing HPLC purity at 99% or above and endotoxin levels below 0.1 EU/mg. The COA is available on the product page before purchase.
How does Real Peptides TB-500 compare on price?
At $4.80/mg (sale price), Real Peptides TB-500 is cheaper per milligram than PeptideGod TB500 at $6.50/mg. It also includes HPLC verification, endotoxin screening, and lot-specific COA documentation that PeptideGod does not provide.
Can I stack TB-500 with BPC-157?
These two peptides are commonly studied together in preclinical settings. Real Peptides sells BPC-157 separately at $43.20 per 10mg vial, though stock availability has been inconsistent. Reconstituting each peptide in its own vial allows independent control over concentration. See our BPC-157 vs TB-500 guide for a detailed comparison.
Is Real Peptides TB-500 currently in stock?
Yes. The product is in stock and ships from US inventory within 24 hours of order placement. This is a notable advantage over the Real Peptides BPC-157, which has experienced intermittent availability issues.
