Smaller syringes offer better visibility for micro-doses
More water = more diluted = easier to measure small doses
For a 50mcg dose, draw to:
= 0.0050ml volume
Your concentration
10,000 mcg/ml
(10mg in 1ml water)
infoVery small dose. Consider using a 0.3ml syringe for better precision, or add more water to increase the volume.

schoolUnderstanding peptide dosing
Step 1: Reconstitute
Add bacteriostatic water to your lyophilized peptide vial. The amount of water determines your concentration - more water means a more diluted solution.
Step 2: Calculate
Use the calculator above to determine exactly how many units to draw for your desired dose. The formula accounts for peptide amount, water volume, and dose.
Step 3: Measure
Using an appropriate insulin syringe, draw the calculated number of units. Smaller syringes provide better precision for micro-doses.
functionsThe dosing formula
Volume (ml) =
Desired Dose (mcg)÷Total Peptide (mcg)×Water Volume (ml)
Then multiply by 100 to convert ml to units (U-100 syringe)
Example: For a 100mcg dose from a 10mg (10,000mcg) vial reconstituted with 2ml water:
100 ÷ 10,000 × 2 = 0.02ml = 2 units
helpFrequently asked questions
Peptide reconstitution is the process of mixing a lyophilized (freeze-dried) peptide powder with a suitable solvent, typically bacteriostatic water. This creates a liquid solution that can be accurately measured and used for research purposes. Proper reconstitution is essential for maintaining peptide stability and ensuring accurate dosing.
ac_unitStorage & handling tips
Keep refrigerated
Store reconstituted peptides at 2-8°C (36-46°F) for optimal stability.
Protect from light
Keep vials away from direct light to prevent degradation of the peptide.
Don't shake
Gently swirl or roll the vial - shaking can damage the peptide structure.
Use within 4 weeks
Reconstituted peptides are typically stable for 2-4 weeks when refrigerated.
