Go with a concentrated Deca,like ttoykko's product. Contains 300mg/ml. So you have to shoot much less volume per injection.
For a Test I'd say Cyp or Enant for 1st cycle..they generally are less painful and your dealing with a single ester....easier IMO to learn how your body responds to dosage......save the Sust and Prop for later cycles when you know how you respond,also Sust=pain + lumps in your ass and Prop= injecting EOD.
I like Dbol and when combined with an antiaromatase like Liquidex,it gives only slight water retention,rapid weight gain and instant stength...otherwise your waiting around for about 4 weeks til trhe Deca/Test really kick in. Plus when I'm bulking there's just something FUN about watching that scale climb by a 1/2 to one pound per day and I don't like to wait. Everyone responds differently to effects and to sides......so some guys hate D-bol,others love it.....you won't know which you are until you try it.
