Gearman Triple Stack and ErgoMax

Does anyone have any experience with the Gearman Triple stack? I am 23 years old and just orderd it, I also have a bottle of ErgoMax whcih they do not make anymore. I was waiting to stack it with the triple stack as I have heard of guys doing this before.

Does anyone know if these supplements will have any real adverse side effects, if so I think I will either sell them or just hold off for a while. Anyway I would appreciate some responses as they are supposed to arrive early in the coming week. Please give me any information you may have on these supplements, I am sure someone has used one or both of them already.
