Where to buy Tesamorelin online

We compare Tesamorelin 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.

How to reconstitute Tesamorelin

View guide

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

Materials needed

Your Tesamorelin 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 Tesamorelin 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? Tesamorelin 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 Tesamorelin vial

With the bac water in your syringe, insert the needle into the Tesamorelin 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 Tesamorelin 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.

Tesamorelin Buying FAQ

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

Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analog, an FDA-approved pharmaceutical (as Egrifta) used clinically to reduce excess visceral fat in HIV-associated lipodystrophy. In the research setting, it is studied for its effects on GH/IGF-1 signaling, body composition, and visceral fat. Products listed here are sold strictly for laboratory research purposes and are not intended for human consumption.

Clinical use is 1–2 mg/day via subcutaneous injection, and most research protocols reference a similar range. Many buyers specifically look for tesamorelin combined with ipamorelin (commonly cited ratios like 10mg/3mg or 11mg/3mg blends dosed once daily), but exact amounts vary by protocol and vial concentration. Always use our peptide dosage calculator to convert a given mg dose into an injection volume based on how the vial was reconstituted, and treat any specific dosing figures as research reference points, not medical advice.

Tesamorelin is typically reconstituted by adding bacteriostatic (BAC) water to the lyophilized powder, injecting the water slowly down the side of the vial rather than directly onto the powder. Once mixed, it should be stored refrigerated (roughly 2–8°C / 36–46°F) and is generally considered stable for a few weeks; unreconstituted (lyophilized) vials should be kept refrigerated or frozen until use. Use our BAC water/reconstitution calculator to get an exact concentration and draw volume for your specific vial size.

All three are growth-hormone-related peptides, but they work differently: tesamorelin and sermorelin are GHRH analogs that stimulate the pituitary's GHRH receptor, while ipamorelin is a ghrelin-receptor agonist (a "GH secretagogue") that works through a separate pathway with minimal effect on cortisol or prolactin. Tesamorelin has a more stable structure and is the only one of the three with FDA approval (for visceral fat reduction), which is why it's frequently studied and stacked alongside ipamorelin or sermorelin in combination protocols.

Combining a GHRH analog (tesamorelin) with a ghrelin-receptor agonist (ipamorelin) targets two distinct receptor pathways involved in GH release, which is why blended vials and dual-peptide protocols are commonly discussed in research literature and forums. Typical research ratios reference dosing them together once daily, but the appropriate amounts depend on the specific vial's concentration and the protocol being followed. This blend is one of the most frequently searched tesamorelin-related protocols on our site — see our dosage calculator for precise measurements.

In clinical use, commonly reported effects include injection-site reactions and joint or muscle discomfort, with more significant concerns including fluid retention and effects on blood glucose regulation. Because tesamorelin influences GH/IGF-1 signaling, clinical guidance calls for monitoring blood glucose during use. This information is for general research education only; anyone considering use for health purposes should consult a licensed medical professional.

Tesamorelin is FDA-approved as a prescription medication (Egrifta) and is legally available only through a licensed prescriber and pharmacy for its approved use. Products sold as "tesamorelin" on research-chemical marketplaces, including vendors compared on this page, are sold strictly for in-vitro laboratory research and are not approved or labeled for human use. Buyers are responsible for understanding and complying with the laws in their own jurisdiction.

Tesamorelin stands out because it's the only major GHRH-class peptide with FDA approval specifically for visceral fat reduction, giving it a stronger clinical evidence base than peptides like sermorelin or ipamorelin, which are typically referenced in broader GH-support or anti-aging research. It's frequently searched against alternatives such as CJC-1295 and other GH secretagogues; our comparison page (sermorelin vs. ipamorelin vs. tesamorelin) breaks down the mechanism and evidence differences in more depth.
