It depends on your dealer. If you could by a little of the one and a little of the other you could make a nice stack. IF you have to choose one or the other I would do Primobolan. Instead of doing it for 8 weeks, I would shorten it to four and double the doses you were going to use. For instance, it you were going to use 200 for the first 4 weeks and 100 mg for the second 4 weeks, I would use 400 mg for the first 2 weeks and 200 for the second two weeks. The reason for this is that first you will probably get your most noticable gains in the first 4 weeks anyway. Second, You can saturate you receptors with more 'roid while their fresh; so the gains you would get would be more pronounced.
There are two reasons why I would chosse Primo. First, the safety factor is better with Primo, second, there is no testicular atrophy so your balls don’t have to recover and you won’t suffer from low testosterone. Also, you tend to keep your gains with Primo.
If you could do a mix stack I would do it this way (dosages are exaples, though they would woork pretty well).A 8 week sample would look like this, 1st 2 weeks, 400 mg of Deca.2nd 2 weeks I would use 200 mg of Deca and 200 mg of Primo. 5th week would be 300mg of Primo. 6th week 200mg Primo. Last 2 weeks, 100 mg of Primo.
A 4 week Stack would be: First 2 weeks would be, 400 mg Deca, 2nd 2 weeks, 200 mg of Deca and 200 mg of Primo. Last 4 weeks I would do 200 mg of Primo.
If you want to do the Deca, I would break it down like this. 1rst 2 weeks 400 mg of Deca. 2nd two weeks, 200 mg of Deca. * If you can get some Clomid go ahaed. Start taking it on your last week. Your normal testosterone levels should be back in no time. If you can’t get Clomid, and reputable Tribulus will help. Past experience with tribulus has proven to be effective in retoring test. levels, for me anyway.
WARNING: You may very well gain over 8 - 10 lbs. I would guess 15 - 20 if done properly.
