Concerned About PCT

i have just started dyna-bol cycle with testosterone cypionate for 8weeks cycle.This is my first cycle.
8weeks cycle:
first week: 100mg cypioante with 10mg dyna evryday
second: 100mg cypioante with 10mg dynabol evryday
third: 200mg cypioante with 20mg dyna evryday
fourth: 200mg cypioante with 20mg dyna evryday
fifth: 300mg cypioante with 30mg dyna evryday
sixth: 300mg cypioante with 30mg dyna evryday
seventh: 200mg cypioante with 20mg dyna evryday
8th week: 100mg cypioante with 10mg dyna evryday

So, i am thinking to start PCT 3weeks after my last injectable with nolvadex only.will that be fine for meh or i have to start PCT 2weeks after my last injectable?

your cycle is weird

Your cycle sucks. No need to comment on PCT at this point.

What exactly is the point of this dosing protocol?

Its just the beginning for me, so i just wanna see how my body reacts with steroids before i go higher with the dosage.
two weeks completed now n i hav gained around 6pounds.Its fine with me because with this low dosage, the results are still noticeable.so if you can help me out with PCT, that ll be great.Whether i need it or not.if yes, then instead of two weeks, can i start it with nolvadex after 3weeks of my last injectable?

There should not be a 2-3 week gap, you will simply feel like shit and may be locked into estrogen rebound.

so shall i start taking nolvadex ryt after my last injectable or after i finish my cycle with dyna-bol?
