YES! That stuff is great! It gives me quite a bit of energy so I always split up the dosage like 2cc morning 1cc afternoon. If you're dieting, you'll notice a good leaning out effect. After about 4 or 5 days of only feeling a slight boost in energy...I noticed a dramatic increase in vascularity and leanness. It's like it "kicked in". It's not as good as AAS but it surprised me at the results I got. As far as size...didn't see much but I did gain strength while on a very strict diet.
Syntheselen it helped me achieving three major things.First it helped me loose a lot of fat. In the mean time I figure out that my aerobic endurance improved substantialy, as well as my muscle gains. If you gonna try it please let me know how it worked for you.
