OTC pct products do not work very well, me personally I see no scenario where a OTC pct is acceptable unless you got bloodwork that shows your not terribly suppressed. Now your only using 4 weeks on Andros (which to be honest is a total waste of time, it's not long enough to make much if any progress more then you could have without the andros.) But because thats all your doing, ya there's a possibility your not going to need a serm. But your guessing, without bloodwork no1 on the planet can tell you if your gonna need it or not.
So looking at your situation as a whole this is what I see.
Person A is using suppressive hormones for 4 weeks which is not really long enough to get desired results but it is potentially long enough to screw up there hormones, then there gambling on a OTC herbs and spices pct (which costs more then a serm) to see if they recover. The risk is high and the reward is low, close to zero actually. If you had 8-12 weeks to run these products then with a really good diet and training program it might be worth while. But in your case and with your timeframe it's not a good setup at all.
On test, tren, Winny and clen your not going to get the transformation your looking for in 4 weeks, and the cycle your running is just a puddle vs. A ocean if you get what I'm saying.
