Tren A for me 1 day. Everyone is different but within the 1st week. Bona cris summed it up well.
Regarding tren and cardio well certain endurance aids will help as they increase cardio output. They are not actually combating trens effects. This post from Lil' Sully on another forum is great advice...
Like a lot of you guys, I had problems in the past with Tren making me short of breath and making it difficult to even do low intensity cardio. I even had it impact my lifting. After a heavy set of squats, I would have a tough time catching my breath. A few times, to the point that I got lightheaded and dizzy and had to sit down for several minutes to catch my breath. I even had one episode so bad that I thought I would pass out.
So, in an effort to run Tren again and make use of it's
fat burning recomp abilities and still do cardio, I did my research. Based on what I read on this board and others, the cause of the shortness of breath was pulmonary constriction brought on by a pseudo-allergic reaction that releases prostaglandins.
And finally, how to combat the release of prostaglandins? Simple. Newly OTC nasal allergy spray Nasacort. It blocks the prostaglandins that cause the inflammation that cause the shortness of breath. 2 shots up each nostril for the first few days, then 1 shot in each after that. All problems solved.
I'm 3 weeks in to 150mg of Tren Ace daily, and I'm rocking the cardio daily. Even LISS cardio used to be almost impossible for me on way less Tren. Now, I'm making daily progress on my cardio. The incline is up to 10.5, and speed is up to 3.5 mph just to hit my lower target heart rate of 120bpm. I've even thrown in a few days of HIIT sprints just to change it up. No problem. Can run and sprint dead out without feeling like my chest is going to collapse and my head is going to explode.
Oh, and no more Tren cough anymore, either.
I understand skepticism guys. If you don't believe me, I challenge u to go out and spend $11 on a bottle of Nasacort and give it a try. Even if it doesn't work for u like it has for me, what did u lose? 11 dollars?
