You have muddled your question.
You ask about the effects on aerobic endurance, but then go on to ask about effects on cortisol, which is not the same thing.
Test increases the number of RBCs per unit volume, thereby giving your blood more O2 carrying capacity. This improves aerobic endurance.
Test partially blocks the action of cortisol, maintaining a pro-anabolic state and reducing catabolism. This has little to do with aerobic performance as such, however it does mean that you should retain more muscle during bouts of prolonged exercsie - all other things being equal.
Hope that helps.[/quote]
yes, I see that now…
I am not asking whether AAS will increase my performance, such as being able to run a marathon faster. What I am looking for is increased tolerance to long duration ‘aerobic’ type workouts, which you pretty much answer in the second part of your answer, and is now pretty obvious to me after a few moments thought.
Of course, the assumption there is that increasing long-duration aerobics type workouts would have a positive effect on endurance capacity/performance, which, in the absence of anything like tren, I suppose would be true.
As for those who mentioned tren…I had an interesting experience at this year’s Arnold Classic in the pump and run (the pump ‘n’ run is where you bench press your bodyweight and then 30 sec is taken off your 5K run time for each rep you complete)…I was entered in the competition and planning to start a tren cycle, but was going to wait until immediately after the race due to tren’s well known endurance killing effects. Well, to make a long-story short, I decided to jump the gun by about a week, figuring the tren will not have ‘kicked in’ enough to adversely affect my running performance…
My bench was amazing and I got 27 reps…but then came the 5K run…in 29 minutes!!! I thought the clock must be broken - I normally run a 5K in about 21 minutes. …and that was as good as my ‘aerobic’ performance got for the rest of the tren cycle - it got so I was winded walking up a flight of stairs. But I DID have an amazing bench, so I’ve always got that…
Older, but sadly no wiser…
