your friend needs to get on here asap bro. nolva wont do anything for deca.. nothing, zip, notta. test is a must. He needs to run a test only if this is his first to see how he reponds to AS (and since test should thoeretically be the base of every cycle start out with that to see how it affects him) 6 weeks isn;t long enough for it to even really kick in minimum 10-12. Test isn;t a necessity to keeping gains but the gains from it are much more retainable then say deca only, since deca will shut down you HPTA "harder" then some other AS. Test will also shut it down but the extend isn;t as severe as say deca.
