## What This Tool Does
ThePepCalc solves a common research problem: determining exactly how many units to draw on an insulin syringe when administering a reconstituted peptide. It eliminates manual math errors by computing the draw volume from four inputs: syringe size, vial peptide amount, bacteriostatic water volume, and desired dose.

## Key Features
- Supports all common insulin syringe sizes (0.3 mL, 0.5 mL, 1 mL)
- Supports peptide vial sizes from 1 mg to 50 mg
- Calculates doses-per-vial
- Visual syringe diagram showing exact draw mark
- Free, instant, no account required

## Supported Peptides (examples)
BPC-157, TB-500, Semaglutide, Tirzepatide, Retatrutide, Ipamorelin, CJC-1295, Sermorelin, Tesamorelin, GHK-Cu, Epithalon, SS-31, NAD+, Thymosin Alpha-1, 5-Amino-1MQ

## Frequently Asked Questions
Q: How do I reconstitute a peptide?
A: Inject bacteriostatic water slowly along the inner wall of the vial and gently swirl until dissolved. Use ThePepCalc to determine the exact draw volume.

Q: How many units do I draw for my peptide dose?
A: It depends on syringe size, vial amount, water volume, and desired dose. ThePepCalc calculates this instantly.

Q: What syringe should I use?
A: Standard insulin syringes — 0.3 mL (30u), 0.5 mL (50u), or 1 mL (100u).

Q: Is ThePepCalc free?
A: Yes, completely free with no signup required.
