How Much BAC Water for Matrixyl?

Quick answer: Add 2 mL of bacteriostatic water to a 100 mg Matrixyl vial. This yields a concentration of 50 mg/mL. A standard 5 mg research dose then requires 0.1 mL (10 IU on a 100-unit insulin syringe).

Concentration by BAC water volume

Concentration and 5 mg draw volume at common BAC water volumes for a 100 mg vial.

BAC water	Concentration	Dose volume	Draw
1 mL	100 mg/mL	0.05 mL	5 IU
2 mL Standard	50 mg/mL	0.1 mL	10 IU
3 mL	33.33 mg/mL	0.15 mL	15 IU
5 mL	20 mg/mL	0.25 mL	25 IU

Dose volume at the standard 50 mg/mL concentration

How draw volume changes if you vary the dose at the standard 100 mg + 2 mL reconstitution.

Dose	Volume	IU draw (100u)
2.5 mg	0.05 mL	5 IU
5 mg Std	0.1 mL	10 IU
7.5 mg	0.15 mL	15 IU
10 mg	0.2 mL	20 IU
15 mg	0.3 mL	30 IU

Reconstitution steps

Wipe the top of both the Matrixyl vial and the bacteriostatic water vial with alcohol swabs.
Draw 2 mL of bacteriostatic water into a sterile syringe.
Inject the water slowly down the inside glass wall of the Matrixyl vial. Do not aim directly at the powder.
Swirl gently until fully dissolved. Never shake.
Refrigerate at 2-8°C protected from light. Allow to reach room temperature before each draw.

Supplies needed

Frequently asked

How much BAC water do I add to a 100 mg Matrixyl vial?

For the standard ASCEND research protocol, add 2 mL of bacteriostatic water to a 100 mg Matrixyl vial. This yields 50 mg/mL.

What concentration does 2 mL BAC water give for 100 mg Matrixyl?

A 100 mg Matrixyl vial reconstituted with 2 mL of bacteriostatic water yields 50 mg/mL. A 5 mg dose then requires 0.1 mL (10 IU on a 100-unit insulin syringe).

Can I use sterile water instead of bacteriostatic water for Matrixyl?

Bacteriostatic water (0.9% benzyl alcohol) is preferred because it inhibits bacterial growth and allows multi-dose use of the reconstituted vial. Sterile water lacks preservative properties and accelerates peptide degradation once the vial is opened.

How long is Matrixyl stable once reconstituted with BAC water?

Most research peptides remain stable for approximately 28 days when reconstituted with bacteriostatic water and stored at 2-8°C protected from light. Refer to peptide-specific stability data for any deviation from this baseline.

What size insulin syringe should I use for Matrixyl?

For a 5 mg dose (10 IU draw), a 30-unit (0.3 mL) U-100 insulin syringe gives the finest resolution. A 100-unit syringe also works.

Can I transport reconstituted Matrixyl?

Keep it cold in transit. An insulated bag or small cooler with an ice pack holds the 2-8°C range for several hours, which covers most day trips or drives. For longer travel, pack it the same way you would any refrigerated medication, and get it back into a fridge as soon as you arrive. Extended time at room temperature shortens the ~28-day stability window.
