I love it man! What ester will you be using and how do you plan to dose?
I always just ran acetate in the past and with a lot of success, so I kinda knew I could tolerate the enanthate before jumping in. I'm lucky in that when it comes to AAS side effects I don't get much and am generally pretty chill so I don't really feel "Tren rage". Obviously everyone is different so I'd suggest using the ace first to see how well you tolerate Tren. I've never used Trestolone but from what I know Tren is basically the Lamborghini to the Trestolone Minivan.
The strength gains are solid and more than likely you'll lean out a lot, especially if your diet is on point. Even if it isn't entirely on point all the time I bet you'd still get a stronger and leaner look than before. The anti-catabolic effects are a plus for me. I'm 6'1", 220 and fairly lean but sometimes I struggle to get all my food in during the work day -tbh honest the Anadrol and low dose Tirz don't help with that. With Tren this seems to not matter as much and my physique doesn't take much of a hit. You'll probably feel much more aggressive and focused in the gym as well. For me the only noticable negative side effect is that my sleep takes a bit of a hit. Instead of 7-8 hrs of sleep I'll often get 6 when on Tren. I added an extra dose last week to hasten blood saturation and only got 5 or 6 hrs a night this past weekend so that sucks, but I'm sure it'll level out this week. I suck at sleep anyway. My libido also skyrockets but I consider that a positive. Obviously blood work tells a different story when it comes to sides and I'll be getting some done next week to see where I'm at. There have also been some studies showing a negative neurological impact from Tren use. I'm not super informed on the neurological effects so can't speak much to it but I imagine there is real validity to it. Just something to consider or research.
