What you get

= 200.0 units (2.00 mL draw)

Mixing 2 mg with 2 mL of BAC water means a full 1 mL syringe — all 100 tick marks — holds 1.00 mg (1,000 mcg). So a 2 mg dose is just part of that: 2,000 mcg ÷ 1,000 mcg/mL = 2.00 mL, which is the 200.0 unit mark on a U-100 insulin syringe for Tesamorelin.

See the step-by-step reconstitution guide Run a calculation How to Safely Reconstitute Your Research Tesamorelin

Use the Tesamorelin peptide calculator to find your BAC water amount, then follow these four steps to reconstitute your vial more carefully and consistently.

1 Sanitize

Wipe the vial stopper and injection site with an alcohol swab. Allow to air-dry for 10 seconds before proceeding.

2 Load Needle

Draw your calculated volume of bacteriostatic water into a sterile syringe. Insert the needle through the vial stopper at a slight angle.

3 Add Water to the Vial

Slowly dispense the water down the inside wall of the vial — never spray directly onto the powder. This preserves peptide integrity.

4 Mix Gently

Swirl the vial gently until the powder is fully dissolved. Do not shake — shaking can denature the peptide and reduce potency.

Read the full reconstitution guide → Calculate your dose → Tesamorelin Storage & Half-Life

Once your research peptide is mixed, proper storage helps it stay more stable and lowers the risk of breakdown or contamination. Use these simple storage basics after reconstitution.

Refrigerate Right Away

Store the mixed vial in the fridge at 2–8°C (36–46°F) as soon as possible. For most everyday research use, this is the standard storage method.

BAC Water Helps

When possible, use bacteriostatic water. It contains a preservative that can help slow bacterial growth, which makes multi-use fridge storage more practical.

Freeze Small Portions for Longer Storage

If you need to store it longer, split the mixed peptide into small sterile vials and freeze those. Thaw only what you need, and do not refreeze once thawed.

Avoid These Common Mistakes

Do not keep freezing and thawing the same vial. Keep it away from heat, light, and room temperature for long periods, since those can shorten shelf life.

Typical storage time can vary by peptide. Many mixed peptides are kept in the fridge for about 3–8 weeks, while frozen aliquots may last longer.

Tesamorelin Half Life Calculator & Buildup in Your System Run a calculation now

Tesamorelin has a half-life of about ~26–38 min — that's how long it takes for half of an injected dose to clear from your system. Because that is short compared with once daily dosing, this Tesamorelin half-life chart shows a single dose rather than a buildup: the 💉 marks the injection and the blue line is roughly how much Tesamorelin is in your system, falling by half each half-life until it's essentially gone — well before the next dose. With so little carrying over, there is almost no buildup between doses.

Check the half-life of: Tesamorelin Compound Tesamorelin See Tesamorelin dosing data → Half-life ~26–38 min Typical cadence once daily Steady state ~1 week

Very short half-life. Tesamorelin acts as a pulse that triggers an endogenous GH release; there is no plasma buildup, so timing (typically bedtime) matters more than steady-state level.

A worked example: Tesamorelin (~26–38 min half-life, once daily) Run a calculation Tesamorelin 5mg or 10mg — Most Common Vial Size

Whether it holds 5mg, 10mg, or some other size of Tesamorelin powder, almost every vial ships in the same 3 mL glass vial — and the vial size sets the maximum amount of BAC water you can add per vial.

2 mL

Standard Tesamorelin fill

Unlike most peptides, a 2 mL vial is actually the most common size for Tesamorelin, typically holding 2 mg of lyophilized powder — reflecting its standard research dosing.

3 mL most common

Common Tesamorelin vial

The 3 mL glass vial is the standard container for Tesamorelin orders, usually filled with 2 mg. This is the typical sealed glass format with rubber stopper and crimp cap.

5 mL

Higher-mg Tesamorelin fill

A 5 mL Tesamorelin vial indicates a higher fill amount, sometimes 5–10 mg for extended protocols. Confirm the labeled content before entering it into the calculator.

10 mL

Likely your BAC water

A 10 mL container in your Tesamorelin order is almost certainly your bacteriostatic water. Tesamorelin peptide vials are small by design — the powder fill is measured in mg, not grams.

15 mL

BAC water diluent

The 15 mL container is your BAC water. Your Tesamorelin is in the small sealed glass vial.

30 mL

This is your BAC water

Your 30 mL bottle is bacteriostatic water. Tesamorelin ships as a tiny dry powder in a sealed glass vial — not in a large liquid container.

Tesamorelin BAC Water Calculator Syringe Guide

Any Tesamorelin vial — whether 5 mg, 10 mg, 15 mg, or larger — can be reconstituted with any syringe size. For example, to mix 2 mL of BAC water into a vial, you could use 2 full draws with a 1 mL syringe, 4 full draws with a 0.5 mL syringe, or about 6.7 full draws with a 0.3 mL syringe. Compare barrel sizes, switch needle gauges, and drag the slider to match your exact dose.

Your peptide calculator result can be measured on a U-100 insulin syringe. A 0.3 mL barrel holds 30 units, a 0.5 mL barrel holds 50 units, and a 1.0 mL barrel holds 100 units. For the clearest markings, use the smallest barrel that fits your full dose. Needle gauge only changes needle thickness — it does not change your unit count.

Key variables that affect your per-dose outcome — from BAC water volume and syringe unit conversion to the administration timing windows that amplify the GHRH-receptor response in visceral adipose tissue research.

Nocturnal Administration and the GH Pulse Window

Researchers consistently administer Tesamorelin at night, at least 2 hours after the last meal. Fasting at injection aligns with the body's peak somatotroph activity — amplifying the natural GH pulse and maximizing the GHRH-receptor response without the suppressive effect of postprandial insulin on growth hormone secretion.

WPA Community Vial Format Preference

The 2mg vial format is the standard daily clinical research dose for visceral adipose tissue reduction — matching the protocol used in FDA trials for HIV-associated lipodystrophy.

How many units is 2 mg of Tesamorelin on a U-100 syringe?

At the standard 2 mg vial reconstituted with 2 mL BAC water, a 2 mg dose is 100 units on a U-100 insulin syringe (1 mg → 50 units). Tesamorelin is prescribed and discussed as "2mg" but insulin syringes measure in units. The mg/mcg toggle in the calculator converts your dose to exact syringe units based on your reconstitution volume — eliminating the manual conversion math that causes measurement errors when working with standard 1mL insulin syringes.

Tesamorelin Reconstitution & Dosage FAQ

How many units is 2 mg of Tesamorelin on a U-100 syringe?

At the standard 2 mg vial reconstituted with 2 mL of bacteriostatic water, a 2 mg dose draws to 100 units on a U-100 insulin syringe (1 mg = 50 units). If you reconstitute the same 2 mg vial with 1 mL of BAC water instead, a 2 mg dose is 50 units.

How much bacteriostatic water do I use for a 10 mg Tesamorelin vial?

Most researchers reconstitute a 10 mg Tesamorelin vial with 2 mL of bacteriostatic water, giving a concentration of 5 mg/mL — at which a 2 mg daily dose is 40 units on a U-100 syringe. Using 1 mL of BAC water yields 10 mg/mL (a 2 mg dose is 20 units), and 5 mL yields 2 mg/mL (a 2 mg dose is 100 units). Enter your vial size and BAC volume into the calculator above to read the exact syringe units.

What is the standard daily Tesamorelin dose in clinical trials?

The FDA-approved Tesamorelin (Egrifta®) protocol for HIV-associated lipodystrophy is 2 mg administered subcutaneously once daily, typically at night and at least 2 hours after the last meal. This is the dose used across the pivotal phase 3 visceral adipose tissue reduction trials.

Can I dose Tesamorelin every other day instead of daily?

The clinical evidence base for Tesamorelin is built on daily 2 mg dosing, so every-other-day (EOD) cadences are outside the approved protocol and have not been validated in the FDA trials. Some researchers experiment with EOD or 5-on/2-off schedules to stretch a vial — the calculator's schedule step will project how long a vial lasts on any cadence you pick.

Originally FDA-approved for HIV-associated lipodystrophy, tesamorelin gained significant attention in 2023 as clinicians applied it to adult GH deficiency protocols. While the FDA approval is narrow to HIV-related visceral fat, research interest has broadened into body-composition and metabolic protocols — which is why search volume for "tesamorelin dosage calculator for weight loss" has grown alongside the original lipodystrophy use case. A 2023 JAMA Neurology study found it improved cognition in older adults with mild cognitive impairment over 20 weeks. Unlike direct HGH, it stimulates the pituitary via the GHRH-receptor pathway — preserving pulsatile GH release, maintaining hormonal feedback, and reducing side-effect risk.

Tesamorelin Side Effects

Every Tesamorelin side effect is determined by exactly four variables. Experienced researchers manipulate these four levers — to minimize risk while pursuing their objective.

T1 · TOOL

Tesamorelin is the T1 variable — the specific compound shapes the entire risk profile. Different peptides carry different mechanisms, receptor affinities, and safety histories. Choosing the right tool is the first lever.

T2 · TOTAL

The dose amount. Tesamorelin at 20 milligrams carries more risk than 2 milligrams of the same compound. Precise dosing — not estimates — is how you control this variable.

T3 · TIMELINE

Duration of use. One day of Tesamorelin vs. ten years of Tesamorelin creates a very different cumulative risk profile. This holds for every compound — cycle length, frequency, and compound rotation are the controls.

T4 · TARGET

Your individual idiosyncratic response. Two people, same compound, same dose, same timeline — different results. Mapping your personal response is an ongoing process.

Prudent first-dose rule: Identify the marketplace consensus dose for Tesamorelin, then start at 50% of that amount to isolate your personal Target response before committing to a full protocol.
