Has anyone here actually tried PDA themselves?

Bringing this thread back up since I'm curious too, especially about the oral version which is said to absorb better than plain BPC.

Looks like just the two of us are wondering about this!

I gave the compounded version a shot and noticed nothing different from BPC. The explanation I got was that it's basically the same as BPC except for one added arginine so it counts as a separate compound.

Mine was the injectable version, not oral.

From what I saw it was meant to improve stability.

Found an interview with a practitioner who mentioned switching his work from BPC over to PDA. Seems like a response to the recent regulatory shift on BPC. He also noted better oral uptake with PDA compared to BPC.

Reviving the discussion again. PDA came up for me recently and I looked into it, quickly seeing the link to BPC-157. A sports research site claimed it has better stability and bioavailability. Given how popular BPC is, why does PDA never show up on peptide lists or gain traction? Anyone know a source? Also, does this mean we're relying on anecdotal use for the injectable since oral effects seem more discussed?
