I have been running BPC-157 for five years and the honest summary is that the effect is smaller than the internet suggests and real.
Mechanism is not outcome, and a plausible pathway is the most expensive kind of evidence there is.
The comparison group matters more than the compound when the outcome is something as fuzzy as focus.
What would change your mind about this?
Test one thing at a time. It feels slower and it is the only way to learn anything.
How long before you can reasonably say something is or is not doing anything?
Same here.
Loose evidence and no evidence are different, and people overcorrect in both directions.
Test one thing at a time. It feels slower and it is the only way to learn anything. Same for me with BPC-157, unfortunately.
