What is Tesamorelin?
Tesamorelin (Tesamorelin (GHRH Analog)) is a research peptide in the growth hormone category. With a half-life of approximately ~26 minutes, it has become an important tool in peptide research.
This peptide has been the subject of growing research interest for its potential applications in growth hormone protocols. Researchers value it for its specificity and well-characterized pharmacological profile.
All research with Tesamorelin should follow proper laboratory protocols and institutional guidelines.

Reconstitution Guide
Materials Needed
- Tesamorelin 5mg lyophilized vial
- Bacteriostatic water (BAC water)
- Insulin syringes (U-100, 29-31 gauge)
- Alcohol swabs
- Sharps container
Step-by-Step Instructions
-
Prepare your workspace — Clean your work area and gather all materials. Wash hands thoroughly.
-
Clean the vial stoppers — Wipe the Tesamorelin vial stopper and BAC water vial with alcohol swabs. Allow to dry completely.
-
Draw the BAC water — Using a sterile syringe, draw 2mL of bacteriostatic water.
-
Add water to peptide vial — Insert the needle into the Tesamorelin vial and slowly inject the BAC water down the inside wall of the vial. Do not spray directly onto the powder.
-
Allow to dissolve — Tesamorelin may take 5-10 minutes to fully dissolve. Gently swirl occasionally — never shake vigorously.
-
Verify dissolution — The solution should be completely clear and colorless. If cloudy or particles remain, continue gentle swirling.
-
Label and store — Write the reconstitution date on the vial. Store in refrigerator immediately.
Dosage Protocol
Concentration Calculations
With 5mg peptide in 2mL BAC water:
- Resulting Concentration: 2.50mg/mL = 2500mcg/mL
- Per unit (U-100 syringe): 25.0mcg per unit
Common Dose Calculations
| Desired Dose | Draw Volume | Syringe Units |
|---|---|---|
| 100mcg | 0.04mL | 4 units |
| 200mcg | 0.08mL | 8 units |
| 300mcg | 0.12mL | 12 units |
| 500mcg | 0.20mL | 20 units |
| 1000mcg | 0.40mL | 40 units |
Injection Guide
Subcutaneous Administration
- Clean the injection site with an alcohol swab
- Pinch a fold of skin (abdomen, thigh, or upper arm)
- Insert needle at 90° angle
- Inject slowly and steadily
- Wait 5-10 seconds before withdrawing needle
- Apply light pressure if needed — do not rub
Site Rotation
Rotate between these areas:
- Abdomen (2+ inches from navel) — most common
- Outer thigh (front/outer area)
- Back of upper arm
