BPC-157 is not FDA-approved for any medical use. It can be sold for research purposes. In the US, the FDA placed BPC-157 on the 503A compounding negative list in 2023 then adjusted the list in 2026 — legal status continues to evolve. Verify in your jurisdiction before purchase or use. WADA bans BPC-157 for athletes.

BPC-157 Reconstitution Calculator & Dosing Guide

Q: How do I reconstitute BPC-157?

BPC-157 typically comes in 5 mg or 10 mg lyophilized vials. A common setup is a 10 mg vial with 2 ml BAC water for a 5,000 mcg/ml concentration — a 250 mcg dose is 5 units on a U100 syringe. Adjust ratios based on your dosing precision needs.

Q: What is the typical BPC-157 dose?

Research protocols commonly cite 250-500 mcg once or twice daily via subcutaneous injection. Some users dose higher (up to 1 mg/day) for acute injury protocols. BPC-157 is an investigational peptide; consult a qualified practitioner for personalized guidance.

Q: How long does reconstituted BPC-157 last?

BPC-157 in bacteriostatic water is typically considered stable for ~28 days refrigerated. Some users report stability up to 60 days, but 28 days is the conservative window. Discard if cloudy or discolored.

What Is BPC-157?

BPC-157 (Body Protective Compound-157) is a synthetic 15-amino-acid peptide derived from a protective protein found in human gastric juice. It is widely studied in animal models for tissue repair, tendon and ligament healing, and gut integrity. Clinical evidence in humans is limited, and BPC-157 is not FDA-approved for any medical use.

BPC-157 is typically sold as lyophilized (freeze-dried) powder for research purposes. Common vial sizes are 5 mg and 10 mg. Users reconstitute with bacteriostatic water before subcutaneous or intramuscular injection.

Common Reconstitution Ratios

Vial size	BAC water	Concentration	250 mcg draw (U100)	500 mcg draw (U100)	1 mg draw (U100)
5 mg	1 ml	5,000 mcg/ml	5 units	10 units	20 units
5 mg	2 ml	2,500 mcg/ml	10 units	20 units	40 units
5 mg	2.5 ml	2,000 mcg/ml	12.5 units	25 units	50 units
10 mg	2 ml	5,000 mcg/ml	5 units	10 units	20 units
10 mg	3 ml	3,333 mcg/ml	7.5 units	15 units	30 units

The trade-off: higher concentrations mean smaller, potentially harder-to-measure draws. If you find yourself drawing less than 5 units on a U100 syringe, add more BAC water to make the marks more readable.

Typical Dosing

Research protocols and anecdotal practice cite a wide range; common patterns:

Maintenance: 250 mcg once daily
Healing protocol: 250 mcg twice daily (morning and evening)
Acute injury: 500 mcg twice daily for 2–4 weeks, then taper
Localized (near injury site): subcutaneous injection as close to the affected area as is safe and practical

Cycle length varies. Anecdotal reports suggest 4–8 week cycles followed by a break, though published human data does not establish an optimal duration.

Storage and Handling

Pre-reconstitution: Freezer-stable long term. Room-temperature-stable for short shipping windows.
Post-reconstitution: Refrigerate at 36–46°F. Conservative stability window: 28 days; some users report longer.
No freeze-thaw cycles — each cycle degrades peptide potency.
Protect from light.
Discard if cloudy, discolored, or particulates appear.

Frequently Asked Questions

How do I reconstitute BPC-157?

A common setup: 10 mg vial + 2 ml BAC water = 5,000 mcg/ml, so a 250 mcg dose is 5 units on a U100 syringe. Adjust ratios if you want bigger or smaller markings for your dosing.

What is the typical BPC-157 dose?

Research protocols cite 250–500 mcg once or twice daily subcutaneously. Some protocols go higher (1 mg/day) for acute injuries. Start low, titrate up as tolerated, and consult a qualified practitioner.

Is BPC-157 legal?

Not FDA-approved for any medical use. Legal for research sale in most US jurisdictions, though 503A compounding regulations have shifted repeatedly. WADA bans BPC-157 for competitive athletes. Verify current legal status in your area.

How long does reconstituted BPC-157 last?

Conservative estimate: 28 days refrigerated in BAC water. Some evidence suggests longer stability, but discard if cloudy, discolored, or past 28 days.

Where do I inject BPC-157?

Subcutaneous is most common (abdomen, thigh, arm). Some users do intramuscular or localized injections near an injury. Rotate sites. The Stackr app tracks site rotation for you.

Can I stack BPC-157 with other peptides?

BPC-157 is often stacked with TB-500 ("Wolverine stack") for synergistic tissue repair effects, or with growth-hormone-releasing peptides. Stacking protocols are anecdotal; no controlled human trials have validated specific combinations.
