Thymosin Alpha-1 reconstitution calculator.
Pre-filled with the 1.6 mg vial and 1 mL of bacteriostatic water the REGEN catalog reports for Thymosin Alpha-1. Every field is editable.
The numbers for a 1.6 mg Thymosin Alpha-1 vial
Reconstituting a 1.6 mg vial with 1 mL of bacteriostatic water gives a concentration of 1.6 mg/mL. On a U-100 insulin syringe, where one unit is 0.01 mL, that puts 16 mcg in every unit drawn.
A 1600 mcg dose at that concentration is 1 mL, which is 100 units on the syringe, and the vial holds about 1 of them.
Those are the values the calculator above opens with. The vial size and water volume are the amounts the REGEN catalog reports for Thymosin Alpha-1; change any field and the arithmetic follows.
What the research reports for Thymosin Alpha-1
Published protocols for Thymosin Alpha-1 report 1.6 mg, 2x weekly. That is what the literature describes, not a recommendation. The calculator starts at the low end of it. The Thymosin Alpha-1 reference page carries the evidence grade, the side-effect profile, and the primary sources behind that range.
Thymosin Alpha-1 reconstitution chart for a 1.6 mg vial
The same 1.6 mg of Thymosin Alpha-1 at four common water volumes. More water does not mean more compound, it spreads the same amount across a bigger volume, so the same dose is drawn to a higher number of units. That is usually the safer direction to be imprecise in: small errors on a longer draw matter proportionally less.
| Bacteriostatic water | Concentration | Per unit (U-100) | Units for 1600 mcg |
|---|---|---|---|
| 1 mL (catalog) | 1.6 mg/mL | 16 mcg | 100 units |
| 2 mL | 0.8 mg/mL | 8 mcg | 200 units |
| 3 mL | 0.53 mg/mL | 5.3 mcg | 300 units |
| 5 mL | 0.32 mg/mL | 3.2 mcg | 500 units |
"Units" here means syringe graduations, not international units. They are unrelated measures that share a name, and conflating them is its own category of mistake. The reconstitution calculator explains the arithmetic behind these columns in full.
