Diesel Nut Diesel Test Hardcore has always provided me with great results such as libido, strength increase, better sleep,
good sense of well being, a little aggressiveness in and out of the gym and most importantly better wood.
I've also had good experience with SNS Bulbine, where I had better erections, libido increase, body composition took on
a harder and more vascular look, and enhanced restful sleep at night.
Those have been two of the many different herbals that I've tried over the years where I really experienced good results.
I know a few people mentioned Magnitropin which seems to be getting VERY GOOD reviews and I just ran two months of
it but didn't see that much from it but then again everyone is different so that might be something to look into.
