Honestly brother why are you in such a rush to jump into Tren? You've only done two cycles of Test. Your only 22 years old. Man I was 36 before I tried Tren. Back when I was your age I was running Test, Deca and Dbol with insane results. So what's the rush to jump onto the most powerful anabolic out there? You still have so much you could achieve without Tren.
I understand being impatient I really do, but I just think your going to miss out on some killer gains with a lot less harmful components.
You say your last cycle was 1.5ml for 10 weeks. So was that 375mg of Test a week? Come on man. That's not even enough to say it was a decent cycle. If I were you I would just run a basic Test and Deca cycle for say 12 weeks. Run your Test around 500mg a week and the Deca around 400mg a week. I've made some great gains over the years running this stack. Later you can throw some Dbol or anavar or Winstrol. Although Winstrol would really be my last choice because of how harmful it is to the liver. At your age you have such a long time to run as many cycles as you want so there's no need to rush.
Of course your going to do what ever you want so if you decide to jump on the Tren train then be careful and listen to your body. And above all get Bloodwork done throughout your cycle plus at the beginning and end of your cycle. No need in jeopardizing your health brother. Also I take daily pins of Tren Ace. So I would recommend you start off at 50mg daily of Ace. I take 100 to 125mg daily of Tren Ace with no sides except blood pressure and breathing. I've figured out how to manage high doses of Tren by giving blood and eating healthy. But some people have way worse sides. If you are an aggressive person then Tren can wreck havoc on your temper. Just be aware that you are on Tren and it is the cause for your aggressiveness and try to keep it under control. I'm a pretty easy going laid back kind of guy so it doesn't seem to have that effect on me but it might you.
Read up on all the sides involved with Tren and be aware of them while you're on your cycle.
One major factor Tren has on me is breathing. I've pinned a vein before with Tren and I could not breath. It nearly closed off my throat. I thought I was going to die from not being able to catch my breath to coughing non stop. Another time I had to run up four flights of stairs at my job while I was on Tren and I could not catch my breath. It literally scared the shit out of me. So just be aware of what you are doing to yourself and be careful.
Good luck in your journey and just remember you have several years to cycle so just be safe and enjoy being young.
