Id run ostarine at 25mg a day bro, that is generally the correct dosage for it and id also go 8 weeks not 6.
Also to say you wont need a post cycle therapy (pct) is wrong everybody's different, and while some may not, others will and advise you have one.
Iv seen some guys test levels halve in 4/5 weeks on ostarine and it can be suppressive although milder than AAS.
I regularly use sarms for bridges after my cycle and for standalone usage as well and this is how'd id run your stack:
1-8 Osta 25mg a day (can go 10 imo)
1-8 hcgenerate
post cycle therapy (pct) (mini 3 weeker)
9-11 unleashed/post cycle
9-11 Daa powder 3g's a day
