Peptide Dosage Explained: Using a Reconstitution Calculator Safely

If you’re working with research peptides in Canada, one of the most common challenges is getting the dosage and reconstitution right. Whether you’re researching BPC-157, CJC-1295, or GHK-Cu, accurate dosing is key for consistent, reliable results.

In this post, we break down how to calculate peptide dosages properly, how to reconstitute peptides safely, and how to use a peptide dosage calculator for error-free measurements.


Why Accurate Peptide Dosing Matters

Peptides are highly concentrated compounds that require precise handling. Miscalculating dosage can:

  • Alter your research outcomes
  • Waste valuable product
  • Lead to contamination or breakdown
  • Misrepresent findings in scientific applications

Proper peptide dosage ensures:
✅ Consistency across tests
✅ Accurate interpretation of results
✅ Efficient use of your compound


Step 1: Understanding Your Peptide Vial

Most peptides are shipped in lyophilized (freeze-dried) powder form, in vials typically labeled by weight (e.g., 5mg, 10mg).

Before you reconstitute, ask:

  • How many milligrams (mg) of peptide are in the vial?
  • How many milliliters (ml) of bacteriostatic water will I use to dilute it?

Step 2: The Reconstitution Formula

Here’s a basic formula you’ll use:

Peptide Concentration (mcg per unit) = Total Peptide (mg) × 1000 ÷ Amount of Diluent (ml)

Example:

You have a 5mg vial and add 2ml of bacteriostatic water.

→ 5mg × 1000 = 5000mcg
→ 5000 ÷ 2ml = 2500mcg/ml

Now, every 1ml of solution contains 2500mcg of peptide.


Step 3: Using a Peptide Dosage Calculator

Rather than doing the math manually each time, it’s easier (and safer) to use a peptide reconstitution calculator.

What It Does:

  • Lets you enter vial size (mg) and liquid volume (ml)
  • Gives you dose per unit (e.g., mcg per 0.1ml or per IU)
  • Helps plan accurate dosing protocols for research

✅ You can find a free peptide calculator on the PHX Labs website soon (coming soon!).
In the meantime, reliable calculators are available online for tools like:

  • BPC-157 dosage calculator
  • GHK-Cu dilution guides
  • TB-500 concentration estimators

Step 4: Safe Reconstitution Best Practices

  1. Use only sterile bacteriostatic water
  2. Wipe vial tops with alcohol before mixing
  3. Inject water slowly down the side of the vial, don’t shake
  4. Gently roll or swirl the vial until fully dissolved
  5. Store reconstituted peptides in the refrigerator (2–8°C)

Pro Tip: Label Everything

  • Vial name
  • Date reconstituted
  • Concentration (e.g., “2.5mg/ml”)

This helps avoid confusion and maintain research integrity.


Legal Note in Canada

Peptides like BPC-157, CJC-1295, and TB-500 are legal for research purposes only in Canada. They are not approved for human consumption or clinical use.

PHX Labs provides high-purity peptides with verified COAs and discreet, Canada-wide shipping for laboratory research.


Final Thoughts

Mastering peptide dosage and reconstitution is essential for valid research outcomes. With a calculator and best practices, you can stay accurate, safe, and consistent in your work.
