Drake I joined a gym in the middle east and it included a program design by a Personal trainer.
I went for three sessions with him before he brought the supplements out.
I didn't take them but did take photo's of the ingredients. Usual pilot thing of having to check before you take.
On web searching them I was quite shocked about what they contained
Amphetamines
Steriods
Pain killers.
Which individually were pretty nasty and bad for you.
But combined they were down right dangerous. One of them the combination of ingredients was dangerous stand alone never mind mixing it with the others.
