Typical vial configurations
A 10 mg vial in 2 mL gives 5 mg/mL, putting a 1 mg draw at 0.2 mL — 20 units on a U-100 barrel — with ten draws per vial. A 5 mg vial in 2 mL gives 2,500 mcg/mL, where 1 mg is 40 units and the vial holds five draws. Enter your own numbers above rather than assuming a standard reading.
Growth-hormone axis research context
Tesamorelin is studied alongside other GHRH and secretagogue compounds such as CJC-1295 and Ipamorelin. Each is supplied at different vial strengths and reconstituted independently, so unit readings are not transferable between them. Run each vial through the calculator separately.
Handling notes
Add bacteriostatic water slowly down the vial wall and allow the cake to dissolve without agitation. Refrigerate once in solution and shield from light. Note the resulting mg/mL concentration on the vial so the syringe reading remains reproducible.
Frequently asked questions
How many units is 1 mg of Tesamorelin?
+
With a 10 mg vial reconstituted in 2 mL, the concentration is 5 mg/mL, so 1 mg is 0.2 mL — 20 units on a U-100 insulin syringe. A 5 mg vial in the same 2 mL gives 2,500 mcg/mL, where 1 mg is 40 units.
How much bacteriostatic water for a 10 mg Tesamorelin vial?
+
2 mL to 3 mL are common laboratory choices, producing 5 mg/mL and roughly 3.3 mg/mL respectively. Both keep a 1 mg draw within an easily readable range on a U-100 barrel.
Can Tesamorelin be mixed in the same vial as another peptide?
+
Compounds supplied in separate vials should be reconstituted and measured separately unless a documented compatibility and stability study supports combining them. Mixing changes the concentration of both materials and makes the syringe reading impossible to attribute to either one.
How should reconstituted material be stored?
+
Once reconstituted, most research peptides are held refrigerated at roughly 2–8°C, protected from light, in the original sealed vial. Bacteriostatic water contains 0.9% benzyl alcohol, which suppresses microbial growth in the diluent. Temperature, light exposure, and repeated freeze-thaw cycles all affect stability, so consult the compound-specific certificate of analysis and published stability data.
How do I read a U-100 insulin syringe?
+
A U-100 barrel is graduated in units where 100 units equal 1 mL, so each single-unit mark is 0.01 mL. To convert a volume in mL to units, multiply by 100 — 0.25 mL is 25 units. This calculator reports both figures so you can cross-check the mark against the volume.
