ok guys post your bad supps experiences to prevent others from making the same mistake.
i'll start with the obvious-cell-tech
had it for like a few weeks before it ran out and it cost heaps. also it wasn't 6x better than creatine or whatever it claimed to be (who would have guessed)

Yohimbine containing products. Bad for your heart, bad for you.

Anything containing Glycocyamine. Increases risk factors for cardiovascular disease.

[goonies86]

supplements containing Guanidinopropoionic Acid (GPA) are pretty useless too

[johnnyironboard]

Yohimbine containing products.

I agree with that.

I'd add DHEA and the methyl prohormones.
