Proper PCT for PH blend?

going to start this month long cycle and was interested on some proper pct advice. Do I need to run a AI with any of these ph's? What would be a good pct for this cycle. Here is the breakdown.

Serving Size1Tablet
Servings Per Container30
Amount Per Serving
Proprietary Blend 250mg
2a, 3a-Epithio-17a-Methyl- 5a-Androstan-17b-Ol
2a, 17a-Dimethyl-17b-Hydroxy-5a-Androstan-3-One
4-Chloro-Dehydro-Methyl-Androst-Diol
Tribulus Terrestris (45% Steroidal Saponins, 5% Protodiocin)

Any help is greatly appreciated:)
