ultra cool peptide calculator

How to Use This Calculator (No PhD Required)

Peptide in Vial: Enter the mg of peptide powder chilling in your vial. Check the label — don't just wing it based on vibes.
Bacteriostatic Water: Enter how many mL you added to bring that powder back to life. This is not the step to improvise.
Target Dose: Enter how much you're actually trying to inject, in mg or mcg. Pick the right unit — this is where most heroic math errors happen.
Syringe Size: Select your syringe (e.g. 1.0 mL / 100 U). Yes, it matters. No, they are not all the same.

Hit Calculate and the tool will spit out your concentration, injection volume, exact units to draw, and doses per vial — so you can stop doing fractions in your head at midnight like it's a personality trait.

Common Syringe Sizes

100-unit (1 mL)

Maximum capacity: 100 units. On a U-100 syringe, 1 unit = 0.01 mL.

50-unit (0.5 mL)

Maximum capacity: 50 units. On a U-100 syringe, 1 unit = 0.01 mL.

30-unit (0.3 mL)

Maximum capacity: 30 units. On a U-100 syringe, 1 unit = 0.01 mL.

Example Calculation Contexts

Example	Amount	Reconstitution	Calculated Units
Example A	2.5 mg	10 mg / 2 mL	50 units
Example B	0.5 mg	5 mg / 2 mL	20 units
Example C	250 mcg	5 mg / 2 mL	10 units
Example D	200 mcg	5 mg / 2 mL	8 units

Examples demonstrate concentration and unit conversion only. They are not dosing recommendations or prescribing guidance.

Safety Tips

Double-check calculations: Verify the entered values and calculation before relying on the result.
Use the correct syringe type: Syringe markings and capacities can differ.
Separate math from medical decisions: A correct unit conversion does not establish an appropriate dose.
Label reconstituted vials: Record the concentration and reconstitution date.

Understanding Concentration

Concentration describes how much peptide is present per milliliter of liquid. Adding more diluent lowers the concentration, while adding less diluent raises it.

Example: 10 mg peptide + 2 mL diluent

Concentration = 10 mg ÷ 2 mL = 5 mg/mL
On a U-100 syringe, 5 mg/mL = 0.05 mg (50 mcg) per unit
A 0.25 mg (250 mcg) amount = 5 units

in case you don't know what the fuck you are doing:

Look, nobody wants to be the person who eyeballed their peptide dose "because math is hard" and ended up either microdosing like a coward or accidentally recreating a science fiction plot. This calculator does the terrifying arithmetic for you, so you can stop squinting at your syringe like it owes you money and just... know how many units to draw. No more "eh, that looks about right," no more calling your smartest friend at 11pm to double-check your fractions. Just clean, boring, correct numbers — because when it comes to sticking yourself with a needle, "close enough" is not a vibe.

The calculator displays the resulting concentration, volume, syringe units, and number of complete calculated amounts available from the vial.
