Effects of clen on cardio output

[bdee69]

i'm a rugby player, i have pretty good natural aerobic threshold and train very hard to be anaerobically fit for rugby/sprinting. I'm thinking about using clen to shed some excess fat. What effects will clen have on my cardio thresholds as i don't want it to be detremental to any aspects of my fitness?

Many thanks

Clen makes cardio extremely difficult. Excpect to be winded all the time if you use it.

My expierences with clen :

1) It makes doing cardio harder...(maybe 10-20% if you want an estimate)

2) I shed fat better when using regular ECA while having lesser side effects at the same time

3) i wouldn't touch clen anymore due to the posibility of it killing heart cells..

Clen will make your cardio workouts more intense.

Killing Heart Cells???

How serious is that? I mean is this chronic use or the 1,2,3 time user of the drug.

clen helps me with cardio, i dont have any problems with it only benefits.

clen is a bronchiolator used to treat asthma? so shouldnt it help with breathing and cardio??? ive used it before and ive noticed that i breath heavily but dont really feel winded when working out intensily or doing cardio.

Wow now come to think of it I was wondering why I was freaking running fast as hell monday and did about 3 miles and was not out of breathe freaky!!

Wow my stamina on the b ball court wuold be amazing, now if I could get rid of these pumps I would be set. either that or get like a skateboard to get up and won the court

I thought clen would help cardio since it is a bronchial dialator, but when I was on it I got out of breath real fast and it felt like there was something heavy on my chest. So for me it didn't help, seems like it hindered. I actually posted a thread asking what the best compound would be for cardio, what do the sprinters and pro athletes use??

I have recently started both clen and cardio. If I have not taken much that day it seems to help, however if I have taken more I have less capacity. I think it's a problem in excess because of the CNS stimulation. You will have less capacity with stronger CNS stimulaters like caffeine or ephedrine. Less capacity is a matter of over amping yourself. Just time your use for advatages. The bronchial dilation is an advantage but at some point has harts going to be to jacked up for to handle a high intensity workout. It's beating to fast before you start.

clen will affect a persons cardio performance differently. with some people it helps it, but more often it hinders it.

even though it does give the bronchodilation effect, the hindrance comes from the elevated hr and elevated metabolism. your body is continuously burning more calories while on it, so it's burning more energy at any given level than usual.

personally, i couldn't do as much cardio as usual while on the clen. it just got my hr up too high. however, even though i had to do my cardio at a slower pace while on the clen, i still got much better results than without.

just watch your hr and don't let your heart race too high for too long.

Yup, I noticed the same thing. I couldn't run at as high as pace as I used to before clen, but running at a lower pace was easier.

even if clen is a broncho dilatator dont expect it to help ur cardio unless u suffer from asthma. As far as anecdotal evidence: clen hinders with my cardio a bit but not that much. Why is this I dont know, there are many possible explanations.. i doubt ascendants explanations covers it all or do u have anythng to back that up? i personally suspect the explanation to be a lil more complex..
