Where to buy TB-500 online

We compare TB-500 offers across vetted research vendors so you can buy with confidence. Every price above is pulled from a verified, in-stock listing — here's what to look for before you check out.

Compare vendors on price-per-mg rather than sticker price, and confirm a third-party Certificate of Analysis (COA) is publicly available before you buy. The comparison table above flags self-tested-only results and account-required vendors so you can filter those out first.

Stick to vendors with no unresolved legal issues or community warnings, and check that stock and pricing were verified recently — the "last checked" date on each listing tells you exactly when. Products listed here are intended strictly for laboratory research use.

Eternal Peptides is operated by Cenvira LLC (Little Neck, NY), a WooCommerce research-use-only (RUO) peptide vendor with a domain registered around May 2025. It publishes a per-batch "COA Library," but its own site currently names Kovera Labs as its testing lab while multiple independent reviews describe Janoshik Analytical instead — an unresolved discrepancy. Independent aggregator Finnrick.com gives it a notably weaker score (63%, ranked #237 of 289 vendors) than its own marketing implies, and it operates a strict no-returns policy paired with historically non-reversible payment methods.

How to reconstitute TB-500

View guide

The materials you'll need and step-by-step instructions for safely mixing TB-500 with bacteriostatic water.

Materials needed

Your TB-500 vial (lyophilized)

Alcohol swabs

Bacteriostatic sterile water

3 mL syringes (Luer Lock tip)

25G or 27G needles (Luer Lock). Other gauges may also be acceptable.

Sharps container (optional)

Remove the caps

Remove the caps from both your TB-500 vial and your bacteriostatic water vial.

Sanitize the rubber stoppers

Wipe down the rubber stoppers on both vials with alcohol swabs and let them dry for about 3 minutes.

Attach the needle

Take your 3 mL syringe and needle. Twist the needle's plastic hub into the Luer Lock tip on the syringe to secure it.

Draw the bac water

Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.

How much bac water? TB-500 typically comes in a 10 mg vial. We recommend 3 mL of bacteriostatic water, though anywhere between 1 mL and 3 mL is acceptable. For larger vials you can use up to 5 mL — more bac water makes microdosing easier, but insulin needles usually max out at 1 mL per injection. That means a lot of bac water might force you into multiple injections to hit your target dose. Unless you're microdosing, 2 mL per vial is a solid rule of thumb.

Insert the needle into the TB-500 vial

With the bac water in your syringe, insert the needle into the TB-500 vial at a slight angle to avoid pressure buildup.

Use a thin needle: Stick to 25G or higher to avoid damaging the rubber stopper. Higher gauge means a thinner needle.

Release the water gently

Let the water run gently down the side of the vial. Don't inject it forcefully.

Heads up: Sometimes the plunger pushes itself in as soon as the needle enters the vial. Hold the plunger back so you have full control over how fast the bac water enters.

Swirl to dissolve

Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.

Be patient: This usually takes 2 to 5 minutes of consistent swirling, mixing in a circular motion, and gently flipping the vial up and down. The water needs to run through the powder many times to fully dissolve it. Don't shake or get aggressive with it.

Check for full dissolution

The solution should be clear with no visible particles. If it's cloudy or clumpy, wait a minute and repeat the swirling step.

Cap, dispose, and store

Once you're done, cap the needle and dispose of it (ideally in a sharps container). Store the reconstituted TB-500 vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How We Rank Offers

We don't just sort by price. Here's how each offer's rating actually gets calculated.

Compared Apples to Apples

We score price per mg against other offers of the same dose size, not the sticker price, so a bigger vial doesn't look like a worse deal than it is.

Price Is Only Part of the Score

We weigh price-per-mg alongside vendor rating, COA purity, and account requirements, so a cheap offer from an unproven vendor won't outrank a fair price from a trusted one.

Trust Gates the Top Ratings

A sub-4.0-rated vendor can't earn "Great value," and missing third-party purity data caps an offer out of "Good" or "Great." No price is low enough to buy around it.

TB-500 Buying FAQ

Straight answers on legality, pricing, and vendor vetting before you buy. For research reference only.

TB-500 is a synthetic peptide fragment derived from Thymosin Beta-4, a naturally occurring protein involved in cell migration and tissue repair. In the research community it is studied primarily for its potential role in soft tissue and wound-healing pathways, often alongside peptides like BPC-157. TB-500 is sold strictly as a research chemical, not for human consumption, and is not FDA-approved for any medical use.

Common research protocols use a higher "loading" dose (around 4-5mg/week) for the first 4-6 weeks, followed by a lower maintenance dose (around 2-4mg/week) if the study continues. Reconstitution involves adding bacteriostatic water to the lyophilized powder and drawing the solution with an insulin syringe based on the vial's concentration — our dosage calculator can help with this math. Always follow the reconstitution and handling guidance provided with your specific product, and store per label instructions.

TB-500 and BPC-157 are frequently studied together as a combination — sometimes referred to informally as a "blend" or the "Wolverine stack" — because both peptides are researched for overlapping tissue-repair pathways. Vendors often sell pre-mixed blend vials (e.g., 5mg/5mg or 10mg/10mg) alongside standalone vials. Dosage math for a blend differs from a single-peptide vial since both compounds share the same reconstitution volume, which is why a dedicated blend calculator is useful.

Thymosin Beta-4 is the full-length, naturally occurring protein, while TB-500 is a shorter synthetic fragment representing its active, actin-binding region. Researchers use TB-500 because it is easier to synthesize and more stable than the full-length protein, though the two are studied for related biological activity. They are not identical compounds and research findings on one do not automatically apply to the other.

Reported effects in available research and anecdotal use are generally described as mild, including injection-site reactions, transient fatigue, headache, or lightheadedness — most commonly during an initial loading phase. Long-term human safety data does not exist because TB-500 has not been through formal clinical trials. This product is sold for laboratory/research use only, not for human or animal administration.

Because TB-500 is unregulated, purity and concentration can vary significantly between suppliers. Look for vendors that provide third-party Certificate of Analysis (COA) testing for each batch, clear concentration/purity percentages, and transparent sourcing — all factors we surface in our vendor comparison table on this page. Comparing price-per-mg alongside COA availability is generally more useful than comparing sticker price alone.
