When to Add SDrol

So I'm planning a moderate cut for spring, probably starting on Sunday, the more I think about it the more I want to hold off on superdrol until the end. Would love thoughts from people who have run similar stacks.

Plans so far:

Weeks 0-5 test E 500 (dnp weeks 2-4 also at 500 before bed)

Weeks 6-8 test E 500 tren E 400

Weeks 9-10 test E 250 tren E 400

Weeks 11-20 test 250 tren E 800

For now i'm thinking superdrol @30mg daily weeks 15-17 and depending on reaction go to 40mg week 18.

(torem, asin, prami, montelukast, t3, mt2 and tudca on hand)

Currently 6' 230lbs, closer to 15% fat. Trying to get away from strength training.
