First of all, if hairloss is an issue he should be running 1mg of finasteride daily while running test to prevent DHT conversion induced hairloss. This eliminates deca, as running nandrolone and finasteride together is a no-no (it causes more hairloss). Test/EQ while running finasteride is my standard stack, and I am someone who is very concerned about hairloss due to genetics. I've never had a problem running 250mg of test and 500mg of EQ in the hairloss department.
