I haven’t tried Biotest supps as it’s a money issue really. I use Dorian Yates - Chemical Nutrition supps. My friend owns a gym and he stocks their products so I get them slightly cheaper. Plus the wife and I have just had a baby boy (Which is the best thing ever…) so money is a bit tight really. I would like to try them though…
I’ve done Ian Kings 12 weeks to super strength and also great guns. Amazing workouts but very humbling seeing smaller guys lifting bigger weights - It was worth it in the end though… I started at about 180lbs and now I’m up to 225lbs - not sure what bodyfat though.
