I think it could provide some benefits, but I wouldn't expect anything wild at such a Low dose, but to say that that it would do nothing or is useless I feel would be an inaccurate statement
@Greenbay68 thr shortness of breath does happen with tren unfortunately, but the dosage would be a large determining factor. The other factor is how good your cardio endurance is. I still run 2-3 miles everyday with tren in my system. It's significantly harder, yes, but it's not like you take tren then suddenly you can barely breathe.
Now if someone doesn't do cardio (or they consider their cardio walking on the treadmill with a low heart rate while playing on their phone), and/or theyre a heavier person, then yeah... I could see the addition of tren being more detrimental to cardiovascular performance and they'd definitely get winded and short of breathe easier
But again at a low dose I don't think the shortness of breathe would really be a concern. Maybe a minor impact if anything
