in my past 20 years or so of hanging out in gyms, things I've seen and heard have lead me to the following conclusions:
The Juice By Itself- not too dangerous
Stimulants By Themselves (aside from coke, meth, etc.)- not too dangerous
The Juice And Stimulants At The Same Time- Very Bad Idea
Alternating The Juice And Stimulants- ??????????
For instance, I consider the ECA stack relatively safe at reasonable doasges when taken by itself. However, I consider taking ECA while on the juice a HUGE mistake. The situation I am least sure about is when people alternate the juice and stimulants. Wondering what others thought...
