Understanding BPC-157 measurements
Milligrams vs micrograms
5mg = 5,000mcg
This matters because doses are measured in micrograms (mcg), not milligrams (mg).
Standard doses:
Low dose: 250mcg (0.25mg)
Standard dose: 350-400mcg (0.35-0.4mg)
High dose: 500mcg (0.5mg)
A 5mg vial contains:
20 doses at 250mcg
14 doses at 350mcg
10 doses at 500mcg
Why 5mg is the standard size
Practical dosing: Matches typical 2-4 week cycles with twice-daily dosing.
Cost effective: Bulk pricing on 5mg vials ($25-40) vs smaller sizes.
Stability: Once reconstituted, peptides last 28 days. 5mg size used within this window.
Industry standard: Most research peptide suppliers use 5mg as base size.
Some vendors offer 2mg or 10mg vials, but 5mg is most common.
How to reconstitute a 5mg BPC-157 vial
Reconstitution means mixing the powder with bacteriostatic water to create an injectable solution.
Standard reconstitution (most common)
Add 2ml of bacteriostatic water to 5mg vial
This creates: 2,500mcg per ml (2.5mcg per unit on insulin syringe)
Easy math:
250mcg dose = 0.10ml = 10 units on syringe
350mcg dose = 0.14ml = 14 units
500mcg dose = 0.20ml = 20 units
Most people prefer this concentration for easy dosing.
Alternative reconstitution, with stronger concentration
Add 1ml of bacteriostatic water to 5mg vial
This creates: 5,000mcg per ml (5mcg per unit on insulin syringe)
Smaller injection volume:
250mcg dose = 0.05ml = 5 units
500mcg dose = 0.10ml = 10 units
Preferred if you want minimal injection volume.
Step-by-step reconstitution
Supplies needed:
5mg BPC-157 vial
Bacteriostatic water (2ml or more)
3ml syringe with needle
Alcohol swabs
Process:
Wash hands thoroughly
Wipe tops of both vials with alcohol
Draw 2ml bacteriostatic water into syringe
Inject water slowly down side of BPC-157 vial (don't aim directly at powder)
Let sit for 5 minutes (powder dissolves naturally)
Gently swirl vial (never shake)
Solution should be clear
Refrigerate immediately
Use our reconstitution calculator for exact measurements.
Important: Never use sterile water (no preservative). Always use bacteriostatic water which keeps peptide stable for 28 days.

Injection technique with 5mg vials
Drawing the dose
Reconstituted with 2ml water (2,500mcg/ml):
250mcg = 10 units
500mcg = 20 units
Process:
Wipe vial top with alcohol
Draw air into syringe (same amount as dose)
Inject air into vial
Invert vial
Draw solution slowly
Remove needle, check for air bubbles
Tap syringe to remove bubbles
Injection sites
Best locations for subcutaneous injection:
Abdomen (2 inches from belly button)
Front of thigh
Back of upper arm (harder to self-inject)
Site-specific injection (optional): Can inject near injury site for localized effect. BPC-157 works both locally and systemically.
Technique:
Clean site with alcohol
Pinch skin fold
Insert needle at 45-90 degree angle
Inject slowly
Withdraw and apply pressure
Rotate sites daily

Common mistakes with 5mg vials
Using wrong water
Mistake: Using sterile water instead of bacteriostatic water.
Problem: No preservative = bacterial growth, peptide degrades in days.
Solution: Always use bacteriostatic water. Extends life to 28 days.
Wrong reconstitution volume
Mistake: Adding 5ml water thinking "5mg = 5ml."
Problem: Makes concentration too weak, unnecessarily large injections.
Solution: Use 1-2ml water for 5mg vial. Use reconstitution calculator.
Inadequate dose
Mistake: Using 100-150mcg doses (too low).
Problem: Below minimum effective threshold.
Solution: Start with 250mcg minimum. Increase to 500mcg if needed.
Inconsistent dosing
Mistake: Skipping doses, irregular schedule.
Problem: Inconsistent blood levels = reduced effectiveness.
Solution: Set reminders, dose same times daily, commit to protocol.
Not using full protocol
Mistake: Stopping after 1-2 weeks when feeling better.
Problem: Incomplete healing, injury returns.
Solution: Complete 4-6 week protocol even when feeling better.
Poor storage
Mistake: Leaving reconstituted vial at room temperature.
Problem: Degrades within days, loses effectiveness.
Solution: Refrigerate immediately after reconstitution.

Calculating your total supply needs
Use this formula:
Daily dose = Dose per injection × Injections per day
Total protocol dose = Daily dose × Number of days
Vials needed = Total protocol dose ÷ 5,000mcg
Example calculations
Standard 4-week protocol (250mcg twice daily):
Daily dose: 500mcg
Total: 500mcg × 28 days = 14,000mcg
Vials needed: 14,000 ÷ 5,000 = 2.8 ≈ 3 vials
Intensive 6-week protocol (500mcg twice daily):
Daily dose: 1,000mcg
Total: 1,000mcg × 42 days = 42,000mcg
Vials needed: 42,000 ÷ 5,000 = 8.4 ≈ 9 vials

Frequently asked questions
Q: How many doses in a 5mg vial?
A: Depends on dose size. 20 doses at 250mcg, 14 doses at 350mcg, or 10 doses at 500mcg. Most people do 250-500mcg twice daily.
Q: How long does one 5mg vial last?
A: 5-10 days typically. Standard protocol (250mcg twice daily) = 10 days. Intensive (500mcg twice daily) = 5 days.
Q: Can I use one 5mg vial for the entire protocol?
A: No. Complete 4-6 week protocol requires 3-9 vials depending on dose. Use our calculator.
Q: What happens if I use less than 5mg total?
A: May not see full results. Complete protocols typically use 10-40mg total (2-8 vials) over 4-6 weeks.
Q: Should I reconstitute all vials at once?
A: No. Reconstitute one vial at a time. Use within 28 days, then reconstitute next vial. Powder stays stable for years.
Q: Is 5mg the same as 5ml?
A: No. 5mg is weight (amount of peptide). After reconstitution, typical volume is 2ml liquid containing 5mg peptide.
Q: Can I split a 5mg vial with someone?
A: Not recommended. Once reconstituted, vial should be used by one person to avoid contamination. Each person needs their own vials.
Q: Why not just buy larger vials?
A: 5mg is optimal. Fits 28-day stability window after reconstitution. Some suppliers offer 10mg but must be used quickly or may waste.
Q: How many 5mg vials for stacking with TB-500?
A: Same BPC-157 supply (3-9 vials). TB-500 separate (typically 4-8x 5mg vials for 4-week protocol). Use stack calculator.
Q: Where do I buy quality 5mg BPC-157 vials?
A: Check our best peptide vendors guide. Look for third-party testing, 97-99% purity, proper packaging.
