Don't want to be part of that yo yo scene. I see the guys on that become cocky, confident and aggressive. Off for 4 months they become meek, depressed, nervous and meek. I'll train natural and will look like a guy that doesn't juice. To me a huge part of training is lowering health risks.
To each it's own. If you want to take anabolic steroids, testosterone, anti estrogens, insulin, GH, LH, pain killers, anti anxiety, EPO,anti depressants, pain medicine, smoke pot, anti inflammatory, blood thinners, Viagra, take some speed to train then more power to you. Just don't expect me to compliment you on your temporary physique.
