Little extra edge in the gym? That's not a good reason to start using AAS. You should use if you've tried everything naturally and still can't continue to make gains. You need to learn a lot more about AAS before you start. I will guarantee that you'll wish that you didn't start so soon in the end...Without proper knowledge you can really screw yourself up.
BUT...If you have already made up your mind on using you should stick around here for the next few months and plan your cycle. Don't just jump into it, because you only get one first cycle. If you don't have your diet and training 100% in check you will be very disappointed in the results. Trust me!
Note:
Steroids are not magic. They are a very small tool that help you gain muscle faster than being "natural" (for me about 2x as fast...but depends on the person, diet, etc.). Even with the steroids I bust my ass every day in the gym. I lift heavy and the weight still feels heavy and I don't grow at super sonic speeds like people think. There are pros and cons of being "on". Cons - You have to worry about so many things such as correct injections(making sure you don't inject into veins. I usually hit a few every cycle, and if I forget to aspirate I could be dead), watching out for infections - which is quite likely if not done correctly, watching blood pressure and heart rate, painful injections, and nasty side effects such as Gyno, hair loss, and bad acne...among other things with far worse consequences such as enlarged heart, or heart attacks.
Guys really need to look at the big picture and make sure that they are willing to accept these risks. These risks can be kept to a minimum with proper monitoring, procedures, diet, and supplimentation. I read on other boards from time to time idiots doing 10-12 week cycles of dbol at 75mg per day...other using the same needle for the whole cycle(non-resusable needles), never aspirating(or knowing what that word means.), and other foolish things that could potentially screw people up bad, because instead of doing research...they would rather just "get big". These people give steroids a bad name, they are the ones you see on talk shows telling america how steroids fucked up their lives and nearly killed them...Sorry for the rant, but I just want people to think about what they are doing, the reasons behind it, and what they are doing to monitor and control their health while using AAS.
BTW...This is not a flame towards you Shadow. Just want you to think about the big picture.
