4,17beta-dihydroxy-4-androstene-3-one is certainly a steroidal compound..
I don't know much about it, been around for awhile but never heard anything one way or another
it doesn't look like it would have much muscle-building action, but rather AI properties
we cannot comment on using other steroidal compounds in conjunction with our PHs..
as for waiting to start 1-Andro, going to depend on how long you have been on the testobol..however, be cautious in your desire to take things you do not understand, and keep in mind these items - tho mild - are not candy
for the question of 3/day 1-Andro: is fine, but I would go 1 AM/2 PM personally, with food
