Man, stay away from lasix. Lasix is a very strong and quick acting dieuretic. It also does not spare your body its normal potassium levels. What this means is, when you hear about a bodybuilder dropping dead after he walks off stage, or has his muscle cramps so badly that he has to be carried off stage, it is probably due to the mis-use of lasix. our body needs a certain level of potassium in it to function properly. This also affects your heart. The potassium in your blood is what causes your heart to beat. No potassium, and your heart can stop. If you are going to use aa dieuretic, get one that is potassium sparing like aldactone. I know quite a few guys that compete on a regular basis and none of them will ever give lasix a second thought. Aldactone works great, but can be a little bit pricey. Just about any source that carries gear will jave lasix as well. One other thing you could do, which is my favorite is to run 50mg/day of proviron. This will help out with just about all estrogen related side effects. Sorry this post is so long, The bottom line is STAY AWAY FROM LASIX. It can and will fuck you up in a hurry. Feel free to email me or shoot me a PM if you have any other questions. Later bro!
