How to Use the Peptide Reconstitution Calculator
This peptide calculator is designed for laboratory professionals who need precise measurements for their research protocols. Whether you are working with BPC-157, TB-500, MOTS-c, Semax, GHK-Cu, Epithalon, PT-141, Tirzepatide, CJC-1295, or Ipamorelin, our calculator provides accurate conversions between milligrams (MG), milliliters (mL), and units (UI).
Step-by-Step Guide
- Select your peptide from the quick-select buttons or enter the mass manually in milligrams (MG)
- Enter the volume of bacteriostatic water (BAC) you plan to use for reconstitution in milliliters (mL)
- Input your desired dose in units (UI) per administration
- Choose your syringe type — U-100 insulin syringes are most common for research
- Click Calculate to see concentration, volume per dose, total doses, and withdrawal units
Common Reconstitution Ratios
- 5MG vial + 2mL BAC = 2.5 MG/mL or 250 UI/dose at 10 UI
- 10MG vial + 2mL BAC = 5 MG/mL or 500 UI/dose at 10 UI
- 10MG vial + 1mL BAC = 10 MG/mL or 1,000 UI/dose at 10 UI
- 40MG vial + 4mL BAC = 10 MG/mL or 1,000 UI/dose at 10 UI
- 100MG vial + 5mL BAC = 20 MG/mL or 2,000 UI/dose at 10 UI
Syringe Unit Reference
- U-100 insulin syringe: 1 UI = 0.01 mL (most common)
- U-50 syringe: 1 UI = 0.02 mL
- U-40 syringe: 1 UI = 0.025 mL
- U-30 syringe: 1 UI = 0.033 mL
Understanding Peptide Concentration Calculations
When you reconstitute research peptides, the concentration is determined by dividing the total mass of the peptide (in MG) by the volume of bacteriostatic water added (in mL). For example, a 5MG vial of BPC-157 reconstituted with 2mL of BAC water yields a concentration of 2.5 MG/mL.
To determine your dose in units (UI), divide your desired dose by the concentration, then multiply by your syringe's units per mL. Using a U-100 syringe (100 UI/mL), if your concentration is 2.5 MG/mL and you want 0.25 MG per dose, you would withdraw 10 UI.
Best Practices for Peptide Reconstitution
- Always use sterile bacteriostatic water containing 0.9% benzyl alcohol — it prevents bacterial growth and allows multi-dose use over 30 days
- Inject BAC water slowly down the inside wall of the vial, never directly onto the lyophilized powder
- Allow 2-3 minutes for natural dissolution — do not shake or agitate the vial
- Store reconstituted peptides at 2-8°C (refrigerated) and use within 30 days
- Keep lyophilized powder at -20°C for long-term storage up to 24 months
- Never freeze reconstituted peptide solutions — freezing destroys the peptide structure

Frequently Asked Questions
Bacteriostatic water contains 0.9% benzyl alcohol which prevents bacterial growth. Unlike sterile water, it allows multi-dose use over 30 days. Never use tap water or non-sterile diluents for research peptides as they can contaminate your compound and compromise research results.
Reconstituted peptides stored at 2-8°C (refrigerated) remain stable for approximately 30 days. Lyophilized powder stored at -20°C remains stable for 24+ months. Always check your Certificate of Analysis for batch-specific stability data.
No. Freezing destroys peptide structure and renders the compound useless for research. Always refrigerate reconstituted solutions at 2-8°C. If you need long-term storage, keep the peptide in its original lyophilized powder form at -20°C.
Gently rotate the vial without shaking. Allow 2-3 minutes for full dissolution. Some peptides like TB-500 may take slightly longer. Do not shake vigorously or use mechanical agitation as this can denature sensitive peptide bonds.
MG (milligrams) measures the mass of the peptide. mL (milliliters) measures the volume of liquid. UI (units) measures the dose on your insulin syringe. For example, 5MG of peptide in 2mL of water = 2.5MG/mL. On a U-100 syringe, 1 UI = 0.01mL, so 10 UI = 0.1mL = 0.25MG of peptide.

To convert MG to UI: First calculate concentration (MG ÷ mL = MG/mL). Then determine mL needed for your dose (desired MG ÷ concentration). Finally multiply mL by syringe units (mL × 100 for U-100 = UI). Example: 5MG in 2mL = 2.5MG/mL. For 0.25MG dose: 0.25 ÷ 2.5 = 0.1mL. On U-100: 0.1 × 100 = 10 UI.
BPC-157 and TB-500 are the most widely studied peptides for tissue repair and regeneration research. BPC-157 is a synthetic pentadecapeptide investigated for tendon, ligament, and muscle healing. TB-500 (Thymosin Beta-4) is studied for cell migration and angiogenesis. Both are available in 5MG lyophilized vials with 99%+ HPLC-verified purity.
MOTS-c, Tirzepatide, and GLP-1 analogs are commonly studied for metabolic regulation. MOTS-c is a mitochondrial-derived peptide investigated for AMPK activation and cellular energy. Tirzepatide is a dual GIP/GLP-1 receptor agonist analog studied for glucose homeostasis. Both ship with full COA documentation.
Store lyophilized (freeze-dried) peptide powder at -20°C in a dark, dry environment. It remains stable for 24+ months when properly stored. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 30 days. Never expose peptides to direct sunlight or extreme heat.
