I'd dump the sdrol after wk 3 or go 20mg the whole way, strictly to avoid over-taxing your body to such a level that it inhibits gains - you've got 6 wks to do this afterall. Unless you've used sd before & know your body loves 30 (in which case congrats). But most ppl saw biggest gains on SD at wk 3. Run more pro-trenbolone after I say. Non-methyl & as strong as you're willing to go - guys have run over 200mg to good effect.
Most say 90 is the minimum for palpable gains, and you'd def need that after dropping sdrol. 60mg during Sdrol for the Tvar, then 90+. You can bump a cap of tvar every several days if you feel good & feel the need. A lot of guys go much higher, but I've known a couple guys who got awesome results at 90.
