testosterone is the male hormone that makes us who we are. MEN! without it, we will end up in real trouble when it comes to cycling. so far, i can see why you have avoided feeling shut down. a short 6 wk cycle of a low dose of var only at 25 yrs old probably would not have shut you down and primo can be effective with little or no test for some. these are about the only dugs you can do this with. heres the thing. you've gone about this backwards. test should be the first steroid you use and it should be the base of every cycle you do. all other steroids were developed off of test. once you start running any steroid, your body begins to shut down natural production of test. some will shut you down harder than others. most steroids will not do for you what test does, as far as feeling normal, healthy and strong with a normal libido and ability to have sex. without test, you will begin to find yourself low on energy, lethargic, weak, experince ED, and generally feel like shit. the only way to keep test in your body while taking gear...is to take test! over time, the more you cycle, the older you get, and the longer you've been "on", and the bigger your cycles get, the more you'll experience this shut down. believe me, you especially dont want to take something like deca without test. any 19-nor compound will shut you down hard. 

back in the golden era, test was believed to be a harsh drug and i've seen the old outdated "steroid profiles" backing this up. i'd suggest you hop on juicedmuscle.com or outlawmuscle.com and do some reading there. you'll see for yourself, that this mind set is way out of date. test should be the first steroid that you lean to use. it can be made to do anything. with less estrogen control, you can use it to gain mass. with more estrogen control, you can use it to cut. i use the same long acting test to diet and as i do to bulk. the key is in the AI's that available today. combine it with the right amount of adex or arom and you would never really need another drug. thats not to say that other compounds wont help you to reach specific goals, but you could get by on just test for an entire career as a rec level BB. you can't say that for any other steroid. 

you dont need to run huge doses to get good results and the more moderate you go, the less chance there is for side effects. if you were to use test for 12 wks, with a low dose of adex, i am certain that you will see the light. a normal dose to start is test 350mg to 500mg long acting test for 12 wks. if you're worried, theres no harm is starting at the low end. in the future, you can do this same cycle with a low dose of dbol (say 20-55mg is pretty low) for the first 6 wks while you wait for the test to kick in. 

1-12

test e or test cyp 350mg

adex- between .25mg EOD should be plenty. if you started to notice side effects from estrogen, you can always take a little more. remember though, this is a fairly low dose so you shouldnt need much. if you lower estrogen too much, you will lower you gains. 

PCT starts 2 wks after last inject.

wk 14 nolva 40mg,

wk 15 and 16 20mg
