Peptide Reconstitution Guide

Introduction

Alright, in this post I'm going to break down how to properly reconstitute your peptides. And I'm going to explain this in the most simple way possible as a resource for myself. Because the number of times I've had to try to explain this and people don't get it, it's actually starting to bother me.

1. Two Important Conversions You Must Understand

1.1. Volume: Milliliters (mL) vs Units

• Most insulin needles have one milliliter.

• On the insulin needle, there are marks for 10, 20, 30, 40, 50.

• On one side: ML / CC — 1 milliliter

• On the other side: 100 units

Meaning:

• 100 units = 1 milliliter

• This is a measurement of volume.

Difference Between Syringes

• Larger syringe (used to mix water) → measured in milliliters

• Insulin syringes → measured in units

• Reason: Units allow more accurate dosing.

  • Bigger syringe = less accurate

  • Smaller syringe = more accurate

  • You can also get 0.5 mL or 0.33 mL insulin syringes

BAC Water

• BAC water vial is 10 milliliters (AKA 1,000 units)

• Again, just a measurement of volume.

---

1.2. Weight: Milligrams vs Micrograms

• Some peptides are dosed in micrograms, others in milligrams.

• Metric system rules apply:

  • 1 milligram = 1,000 micrograms

Example:

• A 20 mg vial of a peptide = 20,000 micrograms.

2. Understanding the Solution

This is your peptide.
Inside is a freeze-dried (lyophilized) powder.

To use it, you must reconstitute it using BAC water.
Once combined → this forms a solution.

Concentration

• Determined by how much water you add.

• Concentration determines how many units you must draw for the desired dose.

---

3. Example: 20 mg Peptide Reconstitution

Using 1 mL of Water

• 1 mL contains the full 20 mg

• If you need 2 mg, that's 1/10th of the solution

• 1/10th of 1 mL = 10 units

• Therefore: 2 mg dose = 10 units

---

4. Concentration Considerations

• Less water → more concentrated

  • Can cause injection irritation

  • Requires more precise drawing

• More water → less concentrated

  • More comfortable, more forgiving for dosing errors

Best practice:

• Use 2 mL instead of 1 mL.

Using 2 mL of Water

• The solution becomes 10 mg per mL

• For a 2 mg dose, you now draw 20 units, instead of 10.

5. Example: 5 mg Tesamorelin

Dose Assumption: 1 mg/day

Using 1 mL of Water

• 1 mL contains 5 mg

• 100 units ÷ 5 = 20 units

• 1 mg dose = 20 units

Using 2 mL of Water

• Now: 2.5 mg per mL

• For 1 mg: draw 40 units

---

6. Example: Human Growth Hormone (Measured in IUs)

Math is the same as above.

Using 1 mL with a 24 IU Vial

• 1 mL = 24 IU

• Half mL = 12 IU

• Quarter mL = 6 IU

Using 2 mL with a 24 IU Vial

• Now: 12 IU per mL

• 100 units = 12 IU

• For 2 IU, divide 100 by 6

• 100 ÷ 6 ≈ 16.6 units

• Round to 17 units

---

7. Why "Units" Mean Nothing Without Concentration

When someone says their dose is "X units," that tells us nothing.

To calculate a real dose, you must know:

1. How many milligrams / IUs were in the vial

2. How much water was added

Only then can you determine:

• What concentration the solution is

• How many units equal the desired dose
