Here's my current stack on LMR products...I'm 6' and 230 - Like you, I was curious and the price was right.
6 week stack at 12cc a day(3cc 4 times a day) of both Nandrotest and Primotest and 8-9cc a day of Nandrovar
As you can see I'm doubling the dose as recommended by someone with ties to the company.
I just started my second week, I think its too early to really know, but I can tell you that my first week was good. On BB inclines I passed my best lift and did it for 2 sets of 4 reps. My muscles feel fullblown all the time, which I wasn't expecting, but I like it.
I'm not about to judge how good they are or aren't until some more time goes by. I'll know in another week or two.
