Sustanon 250 and Tren 150 Cycle Question

Having trouble weeding through the vast amount of information, so I figured I’s start a new thread. Thank you in advance for your time. My aplologies if this is not posted in an appropriate area.

Goal: Lean muscle mass & strength

Okay, so I have had some sucess with Sustanon 250 in previous 2 cycles. My first “cycle” was using something called Tren Extreme orals, which were over the counter at the time, but now banned, and I had no idea that they were more than a supplement. I stacked with D-Bol last time, but bailed because the sides with D-Bol (skin!) were brutal for me.

I am currently in week 6 of a Sustanon 250 cycle, and want to add Tren 150 to the mix before completely tapering off by week 14. I front-loaded the Sustanon following the plan laid out by SquatDemon. This basically was to hit the Sust ED at 0.5CC/125MG to 1.0CC/250MG (multi-injection sites) for the first 3 weeks, and then let the esters do their thing and time release to a taper, which I figure will be completely finished in the next 2 weeks.

I had severe back pump issues during this loading phase, hence the “backing off” to 0.5CC for a few consecutive days until clear. I am experiencing acne now, but nothing that I can’t deal with (I think) until I come off.

FINALLY THE QUESTION: If I inject 0.5CC/75MG of Tren every 3rd day while also taking 20mg of Nolvadex daily, WILL THIS BE A GOOD STACK, OR A BAD IDEA? Remember, I am 43, and am not ever going to compete or anywhere near it - just want some lean muscle which is hard to come by at my age. I have plenty of Clomid and Nolva on hand for a PCT, and am prepared to ditch the Tren at the first sign of trouble.

Again, thank you for your help.
