I usually pin 50mg bilaterally in the muscle I’m training. I’ve done upper chest, lats, and vastus medialis. Dunno if it has localized growth effects for sure but if anything does it seems like no ester testosterone would since it’s active without needing to have an ester cleaved off and it would cause localized inflammation. I will say my upper chest has never grown this well before and the only difference is test suspension.
The original lab I bought it from had some pretty brutal pip a couple of times, but this go around I’m using Azteca Golds and it’s not terrible at all. The pain usually feels pretty intense seconds after pinning but settles down by the time I get to the gym. There was only one day where the pip was brutal for multiple days in my vastus medialis and it wasn’t crippling by any means.
Allegedly the oil based is smoother but it often has guaiacol in it and I’d rather deal with some pip than put that into my body.
