Reconstitution Guide
Everything you need to reconstitute peptides correctly. Bacteriostatic water is included free with every order.
You'll also want: insulin syringes (1ml, 29–31 gauge), alcohol swabs.
Step-by-Step Reconstitution
Remove from refrigerator 15–20 minutes before reconstituting. Cold vials can cause the powder to clump and dissolve unevenly.
Wipe the rubber stopper on both the peptide vial and the bacteriostatic water vial. Let dry 10–15 seconds.
Draw your desired amount of bac water (see table below). Use a clean insulin syringe.
Critical: Insert the needle and tilt it so water runs slowly down the glass wall — not directly onto the powder. This prevents foaming and protein denaturation.
Gently roll the vial between your palms until clear. Do not shake — agitation degrades peptide bonds. If powder doesn't dissolve, wait 5 minutes and swirl again.
Reconstituted peptides are stable at 2–8°C for up to 28 days. Label the vial with the date. For long-term storage, keep lyophilized (unreconstituted) at −20°C.
Reconstitution Volume Reference
How much bac water to add per vial based on the concentration you want.
| Vial Size | Add Bac Water | Final Concentration | Per Unit (IU syringe) |
|---|---|---|---|
| 2mg vial | 1 ml | 2 mg/ml (2000 mcg/ml) | 10 IU = 200 mcg |
| 5mg vial | 2.5 ml | 2 mg/ml (2000 mcg/ml) | 10 IU = 200 mcg |
| 5mg vial | 1 ml | 5 mg/ml (5000 mcg/ml) | 10 IU = 500 mcg |
| 10mg vial | 2 ml | 5 mg/ml (5000 mcg/ml) | 10 IU = 500 mcg |
| 10mg vial | 1 ml | 10 mg/ml (10,000 mcg/ml) | 10 IU = 1000 mcg |
IU = Units on a standard 100-unit insulin syringe. 10 IU = 0.1ml.
Compound-Specific Notes
Common Questions
Can I use regular water instead of bacteriostatic water?
No. Regular water is not sterile and will cause bacterial growth. Sterile water (without benzyl alcohol) can be used short-term but peptides will degrade within 24–48 hours. Bacteriostatic water (0.9% benzyl alcohol) is required for storage.
My solution is slightly cloudy — is it ruined?
Slight cloudiness can occur with some peptides (especially TB-500) and usually clears with gentle swirling. Significant cloudiness or visible particles after full dissolution may indicate degradation or contamination — do not use.
How long is reconstituted peptide stable?
Generally 28 days at 2–8°C using bacteriostatic water. NAD+ degrades faster — use within 14 days. Unreconstituted lyophilized powder stored at −20°C is stable for 24+ months.
Can I mix two peptides in the same syringe?
Yes, in most cases — draw each into the syringe separately. Commonly combined: CJC-1295 + Ipamorelin, BPC-157 + TB-500. Reconstitute each separately first, then draw the desired amount from each vial into one syringe.
