Happy Friday All

So... I am 20 days in to this cycle, on my 10th shot as of lastnight.
100mg EOD Prop
75mg EOD Tren A

I will be quick to point out that the gains are noticable, and I am cutting up very nice. Strenght is just off the chart. I have been keeping a log of all my lifts, and week to week I am blowing them out of the water.

But I am trying to understand why these shots are killing me. I have been doing these shots by the book.... but everytime I pin it hurts with buring pain after. the next 1 to 2 days are even worse.

Can anyone tell me if it is the Prop that is causing this pain. I have not heard of painful tren shots.

Also, if it is the Prop, i am thinking of switching over to Cyp. I will do EOD shots with tren and then 2 x a week shots with Cyp.

Let me know your thoughts...

thanks All
