I'm actually using Clenbuterol right now. I'm using the Perutech 25mcg capsules and they are awesome! I normally use the Ventipulmin Syrup but this time I thought I'd try the caps. They are giving me a huge kick in the gym as well as leaning me out nicely.
I still haven't been able to get over 50mcg's a day. These caps are the strongest that I've ever used. I'm doing the 2 weeks on, two off cycle with it and on my off time, I'll use the ECA stack.
I've still yet to try the NYC stack. That one seems pretty hard to find.
Has your girlfriend used any burners before? Does she have any health issues? If she hasn't tried any burners before, I wouldn't suggest jumping right to the Clen as the side effects can be not so pleasant. If she has any health issues or is using any meds, I would not suggest using any ephedra based burners either. There are tons of burners out there that don't contain ephedrine. I myself prefer the ephedra based products.
Probably the most important thing I should ask is about her diet. How does her diet look? Diet is the number one thing when trying to lean out. There are no magic pills. Training must be in check and diet must be in check.

i use the liquid Clen. ..more cost effective and has worked well for my contest prep...

I am still loving the old formula of exenadrine... but now they have gone ephedra free....that stuff just makes me feel a little OFF....cant explaine it... i prefer to have the CRACK kind...LOL...

I am trying a new product called LIPO 6 by Nutrex Reasearch...i've never heard of it before, but it's got yohimbine HCL in there,,,so we'll test it out...

I am trying to find the NYC, but yes...no one carries it anymore..bummer...Hard to do a search on it...

I used Clenbutrx by VPX for a while...had joint pain associated with it..very odd..never had sides with a otc drug before... like that..

I would say if she hasn't run anything before to try a solid ECA first and see how far her cardio and lifting can go before you throw in Clen. .. I trained for 4 years before i tried anything. It teaches you disipline in your regime and Fyre is 100%...there is no magic pill!

My gf's cycleing clenbutrx (caps) and Clen right now 2 weeks of one, then the other, so on. She REALLY seems to like it. She just started the clenbutrx and didn't think she'd get much of a kick out of it since she'd used Xenadrine so much, but she said it's REALLY given her a jolt. We'll see how it works as far as effectiveness.

LOL, yeah, it really does give you quite a joilt...LOL.... Like a lightning Bolt!

LOL...yeah that's what I heard before she got it. I'm actually thinking about getting some myself. I just came off cycle and was going to do a cycle of Clen and ECA (2 weeks on, 2 off). You think clenbutrx would be fine or should I do something like stacker 2 OR 25 mg's of ephedra w/ tight?
