The stack is flat out amazing. While I would drop the d-bol after 4-5 weeks I would keep the rest going a few more weeks.
Then again I'm on HRT so recovery is a non-issue, but it takes me a good 4 weeks to get Tren A really rolling.
10IU in AM (on days following a workout day) and 10IU post workout seems to be enough.
Haven't gotten to timing the slin pre and post workout yet, but that should be significantly better (although *quite* dangerous, don't try this at home, you'll die, blah, blah, blah)...
