Definitely Tren Ace for a first run.
400 mg is plenty.
I hate Sustanon (sust), personally id go with Prop but to each his own.
I've read so many horror stories about Tren. But upon trying myself for the first time, I've found it to be not as bad as I had originally intended. My only issue is insomnia + night sweats. 3 weeks in and every night I soak my pillow. On both sides. Not my entire bed or my sheets just sweating like a SOB out of my head. I got on a prescription anti anxiety (xanax) and I take Pramipexole for prolactin but it also works great for Restless leg syndrome. So my sleep is OK now, as of last week I was sleeping about 2- 3 hrs a night and since I started the Xanax I'm getting a solid 6 hours so I'm pretty happy with that. Its summer...stay under fans, in AC, all you can do, because I've noticed increased sweating during the day too, not just at night. I'll go to the AC chilled grocery store and break a sweat walking around buying a dozen goodies. Haven't experienced Tren cough, I have experienced the metallic taste in my mouth upon injecting but that doesn't bother me. My only thing is..with Tren and Test...you don't have anything to support collagen synthesis. Both those compounds are great for synthesizing protein and putting on more mass, but they do nothing for your poor joints and bones that are suffering when your weights at the gym are skyrocketing. If you're cutting I'd throw in something like Anavar, maybe some EQ for bulking or cutting, to help out with this. Thats just my 2cc.
