Hey fellas, I just wanted to ask you guys for your thoughts and recommendations, I'm about to start my cycle in about 2 weeks, my gear arrived not too long ago, I told my boy to order me Test E 250 and by mistake he ordered me Test E 300.

one of my questions is being that its my first time going into the point of no return, is it a big difference if I were to pin on the 300 instead of the 250 for 10 weeks (2x a week so it's 600 instead of 500)

my second question is, on my AI I have Arimdx, my plan originally was the Test E 250 along with Arimdx .25mg EOD, now that my gear is Test E 300 my friend is advising that I take .50mg EOD. its completely off from what I have researched and been advised in here.

so I wanted to know where you guys stand on these 2 questions.

My stats are:

height: 5'9
weight: 178lbs (athletic build)
BF: 11-13% Bf

My goals are to gain a little size roughly around 8-12 pounds.

thank you for your time!
