Martini,
I like, for a first stack, 1-Test (estergels) and 1,4 AD (Boldione) and more specifically, the Molecular Nutrition brand. I would frontload the 1,4 AD for at least 2 weeks prior to starting 1-Test. I would then run the two substances together for an additional 4 weeks, then do 4-6 weeks PCT with 6OXO, 600mg ED, split in 2 doses, for the first 2-3 weeks, then drop to 400mg ED for the remaining 2-3 weeks.
Hope this helps, let me know if you need anything else.
