I currently just started a stack of tren, test prop, and mast. I have some shoulder issues so I only lift upper body 3 days a week in order to give time in between for rest.(to minimize flare ups) My question is, is there a "best" time to inject to get the best results? My legs are pretty built but I lack in upper body so that is my main focus. I lift in the morning. I lift upper body on Mon, Wed, and Fri. I inject about an hour prior to lifting on those 3 days. Any advice would be appreciated.
