Using Cardarine with Tren to Preserve Endurance?

I tried some cardarine during my last off cycle in attempt make better use of my nutrient intake. while researching the product, I read it will improve VO2 max during its use. Does anyone have experience with this product as far as preserving cardiovascular endurance during a cycle with Trenbolone?

i never ran it with tren, but i was not impressed with GW-501516…

when i used it, i was doing a lot of MMA training, and i found it hurt my endurance in HIIT sets. for instance, i would gas in about a minute, instead of 2-3 minutes…

however, i caught my breath way faster in rest periods… instead of a minute to catch my breath, it was like 20 seconds, or so.
