I agree with SGFuryZ 100%. You should achieve great gains from a test/deca, test/winny, test/primo cycle etc.

Additionally, stick to the lighter roids while your weight is relatively low, and your body has not developed a tolerance to gear.

What are your stats?

Look into the various tests, Deca Durabolin, Equipoise, Primobolan Depot, Winstrol Depot, things like that. Less 'intense' gear.

Good luck, be smart, and post your stats for better help from a experienced vet. I'm just a reader.
