This guide covers:
- What peptides are
- How to properly mix (reconstitute) peptides
- Why you should never shake peptides
- How to calculate mg and mcg dosing
- How to use a U-100 insulin syringe
- What co-administration (syringe stacking) means
- How long peptides last once mixed
- Why COA verification matters
What Are Peptides?
Peptides are short chains of amino acids that act as biological signaling molecules in the body. They play roles in tissue repair, hormone signaling, and cellular communication.
For a broader medical overview of what peptides are and how they function, see:
- WebMD’s overview on peptides: 👉 https://www.webmd.com/a-to-z-guides/what-are-peptides
- Medical News Today’s peptide guide: 👉 https://www.medicalnewstoday.com/articles/326701
Understanding the science behind peptides helps ensure proper handling and dosing.
Understanding a U-100 Insulin Syringe
A U-100 insulin syringe holds:
- 100 units = 1 mL
- 10 units = 0.1 mL
- 1 unit = 0.01 mL
This allows precise dosing whether your peptide protocol is written in milligrams (mg) or micrograms (mcg).
Conversion Reminder:
- 1 mg = 1,000 mcg
- 500 mcg = 0.5 mg
- 250 mcg = 0.25 mg
Many peptides such as BPC-157 peptide and TB-500 peptide are commonly dosed in micrograms, making accurate unit measurement essential.
How to Properly Mix (Reconstitute) Peptides
Most peptides arrive in lyophilized (freeze-dried) powder form and must be reconstituted with bacteriostatic water.
Mixing Steps:
- Sanitize both vial tops with alcohol.
- Draw bacteriostatic water into your syringe.
- Inject slowly along the inside glass wall.
- Allow the powder to dissolve naturally.
- Gently swirl if needed.

Important: Do NOT Shake Peptides
Peptides are delicate molecular chains. Shaking can:
- Disrupt structural integrity
- Reduce stability
- Cause foaming
- Potentially impact effectiveness
Always gently swirl – never shake.

Understanding Concentration & Dosing
Your final concentration depends on:
- Total mg in the vial
- Total mL added
Example:
10 mg peptide mixed with 2 mL = 5 mg/mL
Since 1 mL = 100 units:
- 1 unit = 0.05 mg (50 mcg)
- 5 units = 250 mcg
- 10 units = 500 mcg
- 20 units = 1 mg
These calculations apply across most healing peptides and anti-aging peptides.

What Is Co-Administration (Syringe Stacking)?
Some users draw multiple peptides into a single insulin syringe before injection to reduce multiple injections. This is commonly called:
- Co-administration
- Syringe stacking
This refers to combining peptides in the syringe immediately before injection — not permanently mixing them in one vial.
Unless professionally formulated as a blend, peptides should not be permanently combined in a single vial.
How Long Do Peptides Last After Mixing?
When properly reconstituted and stored at 2–8°C:
- Most peptides remain stable for 30–60 days
- Growth hormone-related peptides are often best used within 30 days
- Always inspect for cloudiness or discoloration
Using bacteriostatic water helps extend stability by limiting bacterial growth.
Why COA (Certificate of Analysis) Matters
When evaluating authentic peptides in Canada, always request a valid Certificate of Analysis (COA).
A legitimate COA should include:
- Batch number matching your vial
- Purity percentage
- Independent lab verification
- Date of testing
At AlphaPharmCanada.is, transparency and documented third-party testing are core quality standards.
Best Practices for Peptide Use
- Always use sterile syringes
- Never shake peptide vials
- Label mix date
- Store refrigerated
- Double-check mg vs mcg calculations
- Verify COA documentation
