First cycles advice is usually test on its own 500mg. Persoannly id go with Test E or sustanon.
This will probably get some responses, i think a good first cycle is:-
week 1 - 4: dbol 20-30mg/day
week 1 - 12: primo 300-400mg/week
Why? Dbol will give a nice jump up in strength, and at that low dosage and alongside primo, sides are minimal. Primo is very mild, doesnt convert to estrogen and therefore a first time user doesnt have to worry too much about preventing the related sides there and is also easy to recover from with keepable gains.
