How It Works - Peptide Dosage Calculator Methodology
A transparent look at how our calculator determines reconstitution volumes, converts doses to syringe units, and where our peptide data comes from.
The Calculation Process
Our calculator uses a straightforward formula based on three inputs you provide: your peptide vial size (in mg), the desired dose (in mcg or mg), and your syringe size. From these, we determine the optimal reconstitution volume and the exact number of units to draw on your insulin syringe.
Step 1: Reconstitution Volume
Each peptide has an optimal ml-per-mg ratio stored in our database. For a 10mg BPC-157 vial with a 0.5 ml/mg ratio, we recommend adding 5ml of bacteriostatic water. This ratio is chosen so that typical doses fall within a practical range on your syringe.
Step 2: Concentration
We calculate the concentration by dividing the total peptide (in mcg) by the total syringe units. For example: 10mg (10,000 mcg) divided by 500 units (5ml) = 20 mcg per unit. This tells us exactly how much peptide each unit on your syringe delivers.
Step 3: Units to Inject
Finally, we divide your desired dose by the concentration. If you want 250 mcg and the concentration is 20 mcg/unit, you need 12.5 units. We also calculate doses per vial so you know how long each vial will last.
The Math Behind It
Concentration Formula: Concentration (mcg/unit) = (Vial Size in mg x 1,000) / (Reconstitution Volume in ml x 100)
Units Formula: Units to Inject = Desired Dose (mcg) / Concentration (mcg/unit)
Doses Per Vial: Doses Per Vial = (Vial Size in mg x 1,000) / Desired Dose (mcg)
Data Sources
Our peptide database is compiled from published research literature and clinical trial data, FDA-approved labeling and prescribing information, established peptide research community protocols, and manufacturer recommended dosing ranges. We cross-reference multiple sources for each peptide to ensure accuracy.
