do you live in the US? I've never, ever heard of anyone in the US being prescribed that high of a dose for TRT. That puts you well above normal ranges, without a doubt. Your doctor is nuts.
I think you misunderstood Andy's PCT comment. If you are on TRT, you do NOT run a PCT. Ever. You just inject testosterone forever. PCT is for recovering natural testosterone production. This is not your goal.
That's barely any deca. Deca should be run at least 12 weeks in my opinion, and generally at 500mg or higher. You only have enough for like 6-8 weeks, depending on dose. Deca is a long ester. At the very least, you want to run the deca first, not at the end of your cycle, because it takes so long to kick in.
You also didn't say the concentration of the tren A, so I have no idea how much you have of that. If the concentration is 100mg/cc, then you've only got enough to run, say 300mg per week for 7ish weeks.
Poor planning. This is dumb.
