Growth stack

Tesamorelin + Ipamorelin stack calculator

Tesamorelin (a GHRH analogue) is sometimes paired with ipamorelin (a GHRP) to combine two growth-hormone pathways. The two vials have different strengths, so calculate each separately below and combine only the schedule.

Per-compound reconstitution

Each compound is calculated on its own — different vials, different concentrations, different draws. Use these references, then run your exact numbers on each compound's calculator.

Tesamorelin reference

U100 units to draw for each common Tesamorelin dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.

VialConcentration1 mg1.5 mg2 mg
2 mg1 mg/mL100 u(1 mL)150 u(1.5 mL)200 u(2 mL)
5 mg2.5 mg/mL40 u(0.4 mL)60 u(0.6 mL)80 u(0.8 mL)
10 mg5 mg/mL20 u(0.2 mL)30 u(0.3 mL)40 u(0.4 mL)

Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.

Ipamorelin reference

U100 units to draw for each common Ipamorelin dose, by vial size, reconstituted with 2.5 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.

Running tesamorelin with ipamorelin

Tesamorelin and ipamorelin act on different parts of the GH axis, so they are often dosed together. Each vial reconstitutes to its own concentration — tesamorelin doses are in milligrams, ipamorelin in micrograms — so the draws look very different. Calculate each on its own page.

  • Tesamorelin: mg doses; ipamorelin: mcg doses
  • Different concentrations — never share a draw figure
  • Commonly dosed at the same time

Why the draws differ so much

Because tesamorelin is dosed in milligrams and ipamorelin in micrograms, their syringe units differ by an order of magnitude even at the same vial size and water volume. The per-compound reference tables above show each independently so you do not mix them up.

  • An order-of-magnitude difference in dose scale
  • Calculate and draw each separately
  • Track two reconstitution dates and doses-remaining counts

Frequently asked questions

Can I mix tesamorelin and ipamorelin in one syringe?+
Calculate each compound's volume separately first, because the two vials have different concentrations. Combining the two solutions afterward is a handling choice, not a way to skip the separate math.
Which has the larger draw, tesamorelin or ipamorelin?+
Usually tesamorelin, because its doses are in milligrams while ipamorelin's are in micrograms. The reference tables above show each compound's units at its own concentration.
Is tesamorelin a GHRP like ipamorelin?+
No — tesamorelin is a GHRH analogue and ipamorelin is a GHRP. They act on different pathways, which is why they are paired. The reconstitution math is the same for both.
