BPC-157 Tracker

BPC-157 is a gastric pentadecapeptide studied for tissue repair and angiogenesis. This page covers its half-life, what that timescale means for keeping a usable record, and a worked reconstitution example — not what to take or how much.

What BPC-157's timing means for tracking

BPC-157 has one of the shortest half-lives of anything in the catalogue — roughly 1.5 hours, with an estimated activity window around 6 hours and effectively nothing measurable left after about 8. That single fact shapes everything about how a record of it needs to look.

Because it clears within a working day, nothing carries over. Monday's entry has no bearing on Tuesday's levels. There is no accumulation to reason about and no loading period — each administration stands alone.

The practical consequence is that the time of day you record matters as much as the date. With a weekly compound, logging a day late barely changes the picture. With a 1.5-hour half-life, an entry recorded at 8am and one at 8pm describe completely different days. If your log only captures dates, it is throwing away most of the signal.

What to capture in the log

• Record the clock time, not just the date — with this half-life, time of day is the majority of the information.
• If a routine splits into more than one entry per day, log each one separately rather than summing them.
• Note the site if you rotate, since nothing about the previous day's entry constrains today's.

Worked reconstitution example

Purely as arithmetic, using round numbers rather than a recommendation. If a 5 mg vial were mixed with 2 mL of bacteriostatic water, the concentration would be 2.5 mg/mL. Measuring 250 mcg from that would come to:
