How to Reconstitute Reta 10mg: Step-by-Step With Dose Math

Dosing Guide — 2026-10-05

Reconstituting a Reta 10mg vial means adding bacteriostatic water to the lyophilized (freeze-dried) powder so it can be drawn into a syringe and measured accurately. The peptide mass stays the same; the water you add sets the concentration. Here is the step-by-step method and the dose math for a 10mg vial. For laboratory research use only.

Platinum Biolabs ships every Reta 10mg vial with a batch-matched COA at 99%+ HPLC purity. Code PLATINUM25 takes 25% off your order at checkout.

What You Need

• Your Reta 10mg vial (lyophilized powder)
• Bacteriostatic water (the preservative allows multi-use over several weeks — not plain sterile water)
• A sterile syringe to transfer the water
• A U-100 insulin syringe for drawing doses
• Alcohol wipes

Step-by-Step

1. Let the vial reach room temperature and wipe both rubber stoppers with an alcohol swab.
2. Draw your chosen volume of bacteriostatic water into the transfer syringe (see the table below).
3. Insert the needle at an angle and let the water run down the inside wall of the vial — do not squirt it directly onto the powder.
4. Do not shake. Swirl gently or let it sit; the powder dissolves within a minute or two into a clear solution.
5. Label the vial and refrigerate it (2–8°C).

Choosing Your Concentration

How much water you add decides how many syringe units each dose takes on a U-100 insulin syringe (100 units = 1 mL):

Adding 2 mL spreads a given amount across more syringe units, which makes low research doses easier to measure precisely. Adding 1 mL keeps injection volumes smaller. Either is valid — pick the one whose per-dose units land in an easy-to-read range.

Quick Worked Example

Reconstitute the 10mg vial with 2 mL of bacteriostatic water, giving 5 mg/mL. A 2 mg research dose is then 0.4 mL, which is 40 units on a U-100 syringe. See the Reta 10mg dosage guide for how those amounts fit into a titration schedule.

Storage After Reconstitution

• Keep refrigerated at 2–8°C, capped, and out of light
• The solution is generally stable for several weeks in bacteriostatic water
• Do not repeatedly freeze and thaw — see the peptide storage guide

Bottom Line

Reconstituting a Reta 10mg vial is straightforward: add water down the wall, swirl gently, refrigerate. Your water volume sets the concentration and the per-dose syringe units — 2 mL (5 mg/mL) is a common, easy-to-measure choice. The method is identical for the 20mg vial, just at double the water to match.
