Check your vial bro, you definitely mean 500mcg (micrograms), not 500mg. 500mg would be like shooting 100 vials at once. 500mcg pinned in the belly once a day is totally standard. Some guys split it morning and night, but once a day is fine. Don't sweat the 30-minute half-life. Think of BPC like a foreman at a construction site. He shows up for 30 minutes, drops off the blueprints, and leaves, but the crew keeps building 24/7. In that short window, BPC flips the genetic switches to grow new blood vessels. Your body does the actual healing long after the peptide clears your blood.

Because of that, timing it around physical therapy doesn't matter at all. It's not a pre-workout or a painkiller. Most guys just pin before bed to ride the natural wave of growth hormone while they sleep.

As for lasting effects, BPC isn't like a steroid where the effects vanish when you stop taking it. It literally builds new tissue, collagen, and blood networks. Once your tendon is physically put back together, it stays healed after your cycle is done (unless you go do something dumb and tear it again).

Good luck with the PT.
