Being your first cycle, and the shit is not counterfeit, and your training is solid...it will be the best cycle(results-wise according to the strength/size effects asssociated with that particular hormone) that you will ever have. At least with those two drugs. The first hit to the receptors is always the best. I did Test Suspension first cycle. The best gains I ever had with that compound. I still love TS, and get great results from it though, but nothing like that first time.
That being said, noone can tell you what results to expect for you personally brother. Everyone reacts differently. You'll have to find out for yourself over the years(assuming you are in it for the long haul) what effects you will have with any given compound. As far as shutting your natural test levels down, it will. Very mild effects in that reguard though when compared to other hormones you could've chosen. So if that is a primary concern of yours going in, you made a good choice in hormones imo. The "shutting me down" though, can be counteracted with few shots of HCG at the 1/2-way point, and Clomid post-cycle. Personally, I wouldn't waste the two on a low androgenic cycle like yours quite frankly, but if it makes your boat float, then go for it.
Good luck & enjoy!
