Buy TB-500 in Canada
TB-500 is not thymosin β4, and the difference is the first thing to get straight. Thymosin β4 is a 43 amino acid protein that occurs naturally. TB-500 is a short synthetic peptide corresponding to its active region: a fragment, made in a lab, not the whole protein. The two names are often used interchangeably, but they describe different molecules, and the fragment is what the research market sells as TB-500.

We deliver to every province, including Ontario, Quebec, British Columbia and Alberta.
What TB-500 actually is
The compound most suppliers sell as TB-500 is a synthetic peptide reproducing the region of thymosin β4 that the research literature is interested in. Working with a short synthetic fragment rather than the full protein is far cheaper and far more consistent, which is why the fragment is what the research market runs on.
The published work around it concerns cell migration, tissue regeneration and new blood vessel formation, which is also why it so often appears beside BPC-157, a peptide studied around adjacent but separate mechanisms.
You will see it written TB-500, TB500 and TB 500. Those are the same thing. “Thymosin beta-4” on a research listing usually refers to the same short fragment as well.
Buying TB-500 in Canada
It is supplied as a research material, sold for laboratory work as a freeze-dried powder in a sealed vial.
Canadian fulfilment. Every order ships from within Canada, so there is no customs step, just an ordinary domestic parcel between two Canadian addresses, sent to every province.

TB-500 format and specification
- Fragment or full protein. TB-500 is the short synthetic fragment corresponding to the active region of thymosin β4, not the full 43 amino acid protein. The fragment is what research listings mean by the name.
- The milligram figure. 2 mg, 5 mg and 10 mg vials are all sold, and Vistara Labs stocks the 10 mg vial.
- An intact white cake. TB-500 is a white lyophilised powder, supplied as a freeze-dried cake because that form keeps a peptide stable through storage and shipping.
- Published certificates. Certificates of analysis from independent laboratories are published for each compound on our lab reports page, and the TB-500 we stock is above 99 percent purity.
- Research-use framing. TB-500 is supplied for laboratory research only, and our listing describes the compound, its strength and its format.
On its own, or with BPC-157?
TB-500 is very commonly paired with BPC-157, a combination the research community nicknamed the Wolverine stack or Healing Blend. Buying the pair as a blend is usually cheaper than two vials; buying them separately leaves the ratio in your hands. Which makes sense depends on whether the work needs them held independently. That comparison is worth reading before committing either way.
A clinical data point worth knowing: in a 2021 retrospective study, 87.5% of knee-pain patients reported relief after intra-articular BPC-157, given alone or with TB-500. We break down the numbers in our BPC-157 and TB-500 knee-pain study analysis.
Vistara Labs stocks TB-500 as a lyophilised powder, and also carries it in the BPC-157 + TB-500 blend. Shipped from within Canada to every province.
Frequently asked questions
Is TB-500 the same as thymosin beta-4?
Not exactly. Thymosin β4 is a 43 amino acid protein that occurs naturally; TB-500 is a shorter synthetic peptide corresponding to its active region. Most research listings sell the fragment.
Can you buy TB-500 in Canada?
Yes, as a research material from Canadian research suppliers. It is not approved as a medicine in Canada.
Is TB-500 the same as TB500 or TB 500?
Yes: the hyphen and the space are only formatting. All three refer to the same peptide.
What vial sizes does TB-500 come in?
Commonly 2 mg, 5 mg and 10 mg. Vistara Labs stocks 10 mg. Sizes differ between suppliers, so the milligram figure has to be compared directly.
Why is TB-500 sold with BPC-157?
Because the two are studied around related but distinct mechanisms, so the pair covers more ground than either alone. That combination is what the community calls the Wolverine stack.
