I love a low dose test cycle. You can get great gains by test alone if your put the effort into the gym and diet properly. I have used Test C alone at 200 mg a week and gotten slow steady gains. I emphasize slow. Two things worry me though: one is the cycle length 6 weeks is not very long in my opinion. Keep in mind though I am not you, or a doctor and that is exactly what I stated my opionion. That being said, the other thing that worries me is it being a test blend. Only shooting 250 mg of a blend is alot of ester weight. If it were me I would go for test e or c at 200-250 and go for 12-16.
Cheers
