What do these boxes mean?

In the vial: The amount of powder in the vial before you add anything, e.g. “5 mg”. It’s on the label or the box.
Water added: How much bacteriostatic water you mixed in. It doesn’t change how much peptide you get, only how strong the mix is. More water makes each dose a bigger amount that’s easier to measure.
Your dose: How much peptide you want per injection, from your prescription or plan. Not the number of units on the syringe; that’s what we work out.
Syringe: Check the packet: 1 mL, 0.5 mL or 0.3 mL (sometimes written 100, 50 or 30 units). All are U-100: 100 units is 1 mL. Smaller syringes measure small doses more accurately.

BPC-157 units to mcg chart

Syringe units on any U-100 insulin syringe (100 units = 1 mL), worked out by the same engine as the calculator. Your own vial and water may differ: use the calculator for your numbers.

5 mg vial + 2 mL water (2,500 mcg per mL)
Dose	Units	mL
200 mcg	8	0.08
300 mcg	12	0.12
500 mcg	20	0.2
600 mcg	24	0.24

10 mg vial + 3 mL water (3,333 mcg per mL)
Dose	Units	mL
200 mcg	6	0.06
300 mcg	9	0.09
500 mcg	15	0.15

BPC-157 questions

How many units is 200 mcg of BPC-157?

With a 5 mg vial mixed with 2 mL of bacteriostatic water, 200 mcg is 8 units (0.08 mL) on a U-100 insulin syringe. A different vial size or amount of water changes this, so check it with your own numbers.

How much water do I add to a 5 mg BPC-157 vial?

2 mL of bacteriostatic water is common, which makes 2,500 mcg per mL. More water makes each dose a bigger amount that is easier to measure; it doesn't change how much is in the vial.

How long does mixed BPC-157 last?

Once mixed, keep it at fridge temperature, 2–8°C and use it within 28 days. Unmixed powder: freezer −20°c.

What is BPC-157?

BPC-157 is a lab-made chain of 15 amino acids based on a protein found in stomach juice. It’s widely discussed for healing tendons, muscle and the gut, but it isn’t approved for use in people, and it’s banned in tested sport.

What the research shows

Animal studies report faster healing and new blood vessel growth. No large human trials have been completed, so whether it works in people, and what the risks are, isn’t known. The FDA has raised safety concerns about it.

The mcg trap

Vials are labelled in milligrams but doses are quoted in micrograms. 1 mg is 1,000 mcg, so a 5 mg vial holds 5,000 mcg. Reading one as the other is a thousand-fold error; the calculator keeps the two units apart and shows the unit next to every number.

Where people inject

Some people inject near an injury, on the theory that closer is better. That hasn’t been tested in people; injecting under the skin of the belly is the usual alternative.
