Agree with the above - primo depot takes about 5 weeks to hit "full strength". Voice change / cracky voice is very common , so expect that. I don't recall how quickly it comes on tho. Did you notice any hair loss starting? If I were looking for primo-ish sides, I'd be looking for that. If your var was actually dbol (very common fake), detection time is 5-6 weeks. However you are also accumulating over the duration of your cycles.
That said - what was the 'primo' dose? When comparing cycles I like to look at weekly dosing equivalents - so for ex, if you were doing 100 mg primo / week, would that be any worse (in terms of sides) than 100 mg of test prop / week. Its a bit aggressive if we compare probably a typical test prop cycle of say 30 mg e3d. In terms of androgenic sides, I don't consider prop to be any "worse" than primo - however prop aromatizes, so you'd be seeing some water retention vs dry progress. As mentioned, you'd see more hair loss on primo, but prop is also a much shorter acting compound. You'd also see it clear in 2-3 weeks. If you see water drop when you come off, then coulda been prop.
A thought I had on this adam's apple thing - could be an irritated gland? I'm thinking of when people get the scratchy throat / low grade fever, etc. when winstrol doesn't like them very much. I really can't imagine this adam's apple thing in 3 weeks - in fact I don't know that I've ever actually seen something like that before short of something like sex change hormone therapy.
