FIRST injectible Cycle (Scared)

[LuigiBellucci]

I did my first oral cycle with D-Anabol few months ago and I had some amazing very very very amazing results without any side effects. I dont know if it is the Steroid or the good genetic. I was only 68 kilos and after only 12 weeks I was 87 Kilos and of corse I had a good diet and I trained 6 times a week with my special workout my father gave me..since he did bodybuilding back in Italy...and I had only about 15% bodyfat..I unfortunatelly went down to 78 kilos recently going thru some problems so I lost pounds.

I am 21 1.78cm 78kilos 9-10%bodyfat

I finally after 2 months of research I finally found a 100% legit source and I am ready to order some Deca Sustanon and some more D-Bol.. I am scared and I dont want to hurt myself in any way I never used before any injectible in fact I never ever inject anything to myself.
My question is how much DECA should I inject for the first time in my life ? I know Deca you should inject it twice every week for about 12 weeks but I dont know eactly how much the quantity each time.....I read a lot about these 3 and it depends on weight in general...and since I am not an expert I am asking you guys!

Thanks - Luigi
