You got your first peptide vials. You opened the box and now you are staring at two bottles of powder, a bag of insulin syringes, and a vial of weird-looking water. No judgment — everyone starts here.
This guide walks you through exactly how to mix BPC-157 and TB-500: the right order, the right amounts, how to draw them, and how to keep everything sterile and safe.
The Golden Rule: Never Mix During Reconstitution
Before anything else: always reconstitute each peptide in its own separate vial. Never add BAC water to both peptides in the same container. The vials are your storage containers, not mixing cups.
Here is why this matters:
- Each peptide has a different concentration based on how much powder is in the vial
- You need to control the dose for each compound independently
- Once mixed together in a single vial, you lose that control permanently
So two peptides = two vials. Always.
What You Need
Before you start, gather:
- BPC-157 vial (usually 5mg or 10mg of powder)
- TB-500 vial (usually 5mg or 10mg of powder)
- Bacteriostatic water (BAC water) — 30mL vial, available on Amazon or from your peptide supplier
- U-100 insulin syringes — 31g or 32g, half-inch
- Alcohol prep pads — wipe everything before you start
- A clean flat surface
BAC water is sterile water with 0.9% benzyl alcohol added as a preservative. This is what keeps bacteria from growing in your reconstituted peptides. Plain sterile water or saline from the pharmacy will not work the same way — the benzyl alcohol is essential for long-term storage.
Step 1: Reconstitute Each Vial Separately
Take your first peptide vial (BPC-157) and add the BAC water.
BPC-157 Reconstitution
For a 5mg vial of BPC-157:
- Add 1mL of BAC water
- Concentration = 5mg/mL (or 5000mcg/mL)
- For a 250mcg dose: draw 5 units on a U-100 syringe
- For a 500mcg dose: draw 10 units
For a 10mg vial of BPC-157:
- Add 2mL of BAC water
- Concentration = 5mg/mL (same math — more convenient dosing)
- For a 250mcg dose: draw 5 units
- For a 500mcg dose: draw 10 units
How to add the BAC water: Pull the BAC water into your syringe. Insert the needle into the top of the vial at an angle — aim for the glass wall, not the powder at the bottom. Slowly push the plunger so the water runs down the side of the glass. This technique keeps the pressure inside the vial even and prevents the powder from frothing.
Once the water is in, gently roll the vial between your palms for 10-20 seconds. Do not shake it. Shaking creates air bubbles and can damage the peptide structure. It will look clear or slightly cloudy at first — that is normal. It will clear as the powder fully dissolves.
TB-500 Reconstitution
For a 10mg vial of TB-500:
- Add 2mL of BAC water
- Concentration = 5mg/mL
- For a 2.5mg dose: draw 50 units (0.5mL) — a comfortable injection volume
For a 5mg vial of TB-500:
- Add 2mL of BAC water
- Concentration = 2.5mg/mL
- For a 2.5mg dose: draw 100 units (1mL) — doable but a larger injection
The math works out cleaner with a 10mg vial. If you can get 10mg TB-500 instead of 5mg, your dosing will be easier.
Repeat the same reconstitution process for TB-500 in its own dedicated vial.
Step 2: Draw Your Dose (One Syringe or Two?)
Here is the part that confuses most beginners: can you draw both peptides into the same syringe?
Yes — but only AFTER reconstituting them separately.
After you have reconstituted BPC-157 in one vial and TB-500 in another, you can draw from both into a single syringe before your injection. This is completely safe and cuts down on the number of shots you take.
Drawing from two vials into one syringe
- Draw air into your syringe (equal to the volume you plan to draw)
- Insert needle into BPC-157 vial, push air in, and draw your BPC-157 dose
- Remove needle, insert into TB-500 vial, push air in, and draw your TB-500 dose
- You now have both in the same syringe — ready to inject
Total injection volume should stay under 2mL per site. For most people using standard reconstitution volumes, this is not a problem.
Step 3: Inject SubQ
Both BPC-157 and TB-500 are injected subcutaneously (into the fat layer just under the skin, not into the muscle).
Standard injection sites:
- Lower abdomen (2 inches away from the belly button, left or right side)
- Upper thigh
- Upper arm (back of the arm, subQ fat)
How to inject:
- Clean the injection site with an alcohol prep pad
- Pinch the skin at the site
- Insert needle at a 45-degree angle (for most people)
- Push the plunger slowly — do not rush
- Hold the needle in place for 5 seconds
- Withdraw and apply light pressure with the prep pad
- Done
For BPC-157 specifically: if you are targeting a specific injury (shoulder, knee, elbow), you can inject near that site. For TB-500: the injection location does not matter since it distributes systemically.
Step 4: Storage
- Refrigerate reconstituted vials immediately
- Stable for 4-6 weeks in the fridge after reconstitution
- Do not freeze reconstituted peptides
- Unreconstituted powder vials: store in a dark, cool place (room temperature is fine before reconstitution)
- Label your vials with the date you reconstituted them
Common Beginner Mistakes to Avoid
Mistake 1: Using plain sterile water instead of BAC water
BAC water has the benzyl alcohol preservative. Without it, bacteria can grow in the reconstituted peptide within days. Always use bacteriostatic water.
Mistake 2: Shaking the vial to dissolve
Shaking creates air bubbles and can denature the peptide. Roll gently instead.
Mistake 3: Mixing both peptides in one vial during reconstitution
Separate vials. Full stop. This is not optional.
Mistake 4: Keeping reconstituted peptides at room temperature
Once mixed with BAC water, refrigeration is mandatory. Room temperature storage drastically reduces shelf life.
Mistake 5: Reusing syringes
Insulin syringes are single-use. Never reuse — the needle dulls after the first use and sterility is compromised.
Standard Protocol at a Glance
| Compound | Dose | Frequency | Route |
|---|
| BPC-157 | 250-500mcg | Once daily | SubQ |
| TB-500 | 2.5mg | 2x/week (loading) | SubQ |
Run the loading phase for 4-6 weeks, then drop to maintenance (TB-500 once weekly, BPC-157 daily or 3x/week).
Track Your Protocol
Logging what you inject, when, and how much — plus your pain levels and progress — makes it easy to adjust your protocol if needed. PeptIQ lets you track BPC-157 and TB-500 dosing, injection sites, and symptoms in one place.

Where to Source BAC Water and Peptides

Summary: Reconstitute BPC-157 and TB-500 in their own separate vials with BAC water. After reconstitution, you can draw both into the same syringe for one injection. Inject subQ daily for BPC-157, 2x/week for TB-500 during loading. Refrigerate after reconstitution, do not reuse syringes, and log your protocol to track results over time.
