Your dose, on the dial.
The dial counts in units of 0.01 mL: 10 units is 0.10 mL, and 100 units, the most one press gives, is 1 mL. How much peptide a unit holds depends on the pen’s strength, so the same number of units gives a different dose on each pen. Enter the dose your doctor gave you to see how many units to set.

About BPC-157
What BPC-157 is
BPC-157 is a short chain of 15 amino acids, first developed in Croatia from a protein found in the stomach. It was studied as a possible treatment for bowel disease, and later for injuries to tendons, ligaments and muscle.
Nearly all its research is in rats. No study has yet tested it in people against a placebo, or given it to people by injection under the skin.
What BPC-157 is studied for
- Tendons and ligaments: Studied in rats with a cut Achilles tendon or knee ligament.
- Gut: Studied in rats for stomach ulcers, fistulas and inflamed bowels, where its research began.
- Knee pain: Studied in one clinic’s report of 12 people given injections into the knee, with no comparison group.
What the research shows.
BPC-157 is a short peptide first developed in Croatia as a possible treatment for bowel disease. Nearly all its research is in rats, and no study has yet tested it in people against a placebo. Each study used its own supply, dose and schedule, so its results describe that study rather than promise what this pen will do.
Tendons and ligaments
Animal studies, Rats
In rats with a cut Achilles tendon or knee ligament, the tissue healed stronger and more orderly when the rats were given BPC-157.
An independent test
Animal studies, Rats
A test in rats by a lab outside its original research group found no clear effect on tendon strength after four weeks.
Gut
Animal studies, Rats
In rats, it has been studied for stomach ulcers, fistulas and inflamed bowels, which is where its research began.
In people
Small studies, Into the knee
In one clinic’s report, with no comparison group, 11 of 12 people given BPC-157 injections into the knee said their pain had eased.
How every lot is tested
Every lot of BPC-157 goes through three tests before it is sold.
-
Every lot is 99% pure or more, and your pen’s exact purity is printed on its tube.
-
Every lot we sell has passed the sterility test: no bacteria or other microbes were detected.
-
Every lot we sell has passed the test for endotoxins, traces of bacteria that can cause fever after an injection.
-
An independent laboratory in the USA runs every test.
Side effects and cautions
-
No published study has given BPC-157 to people by injection under the skin, and no safety data from people exist.
-
In lab studies, BPC-157 helps new blood vessels grow. Whether that could affect a tumor has never been studied.
-
The World Anti-Doping Agency bans BPC-157 in sport at all times, so an athlete who is tested for doping and uses this pen risks a violation.

Allergy warning
Don’t use BPC-157 if you have ever had an allergic reaction to it or to anything else in the pen. Get help straight away if you have swelling of the face, lips or throat, trouble breathing, or a rash that spreads after an injection.
Pregnancy and breastfeeding
BPC-157 has not been studied in pregnancy or breastfeeding. If you are pregnant, trying to become pregnant or breastfeeding, talk with your doctor before using it.
Medicines and health conditions
If you take any medicine or have a health condition, talk with your doctor before using BPC-157, and tell them you use it.
Cancer
In lab studies, BPC-157 helps new blood vessels grow, and in mice, extra thymosin beta-4 made melanoma tumors grow larger and spread. Talk with your doctor first if you have or have had cancer.
Age
For adults 18 and over.
Frequent questions
Is BPC-157 right for me?
BPC-157 has been studied mostly in rats, for injuries to tendons, ligaments and the gut. Because it hasn’t been tested in people against a placebo, no one can yet say how well it works in people. Talk with your doctor before you start.
How often is BPC-157 taken?
No study in people has set a schedule for BPC-157 under the skin. Follow the schedule your doctor sets.
What side effects can BPC-157 cause?
No published study has given BPC-157 to people by injection under the skin, so how it acts that way in people, and its side effects, are not known. Tell your doctor about any reaction where you inject it, or anything else unusual.
Can I use BPC-157 with TB-500?
Many people do, and Wolverine puts the two in one pen, so one injection gives both. In the only test of the two together, in rats, they healed a tendon no better than either one alone.
What testing does Pure99 complete for BPC-157?
Every lot of BPC-157 is tested by an independent laboratory in the USA before it is sold. The laboratory measures its purity by HPLC, tests it for bacteria and other microbes by PCR, and measures its endotoxins by LAL. Endotoxins are the toxins bacteria leave behind even in a sterile solution, and they can cause fever and aches after an injection.
How much BPC-157 should I take?
Take BPC-157 only as your doctor directs: Pure99 doesn’t recommend a dose. The pen’s dial counts in units of 0.01 mL, from 1 to 100 a press, and the same number of units gives a different dose on each pen. The dose guide on this page turns your dose into the number of units to set.
How many doses are in one BPC-157 pen?
Every pen holds 3 mL, which is 300 units on the dial. How many doses that makes depends on your dose: the dose guide on this page shows how many doses of your size a pen holds.
