forearm

I’m using bpc157 into my forearms for my forearm splints. I started getting these when I increased my volume on my curls at the gym. I’m trying to train my arms atleast 2x a week. I’m right at a dosing of 100mcg EOD going into my forearms between my wrists and elbow. What am I doing wrong...

Had no clue what a forearm splint was until I started researching it online This is exactly what I have I need help fixing this because whenever I do my upper body it starts bothering me can you please suggest a supplement that can cure me
