You could likely get away with an OTC based pct if you run super2 solo; Id use clomid personally.
Id run something like epiandro rather than a tbooster on-cycle; the former will actually add to your gains.
This. I would always advise using a SERM, no matter what. Yes, that may be overly cautious, but that is better than the alternative. You could always add an OTC product to your SERM, but these products should be ran alongside a SERM instead of in its place. Some good options are Sup3r PCT, Kingsblood or AlphaMax XT. I prefer these three options because they are an all in one complete product.
AlphaMax XT contains a full dose of Ashwagandha, which is most known and used for reducing cortisol and helping with stress and anxiety, but there are also studies showing it can improve muscle mass, strength, and endurance, which is beneficial at any time. Ashwagandha has also been shown to increase testosterone and lean mass.

It also contains a full dose of tongkat Ali, another adaptogen that can help optimize hormone levels and balance, which can be especially valuable when dieting. Tongkat can also improve libido, which is always nice. I find the combination of tongkat and Ashwagandha provides a subtle but valuable mood elevation and reduction in stress/anxiety.

AlphaMax XT also contains a full dose of ferulic acid, which has been shown to improve mass and strength, which is valuable any time.
You want to control cortisol during PCT and AlphaMax XT does a great job of that with several different, fully dosed ingredients. TF Supplements has it in stock currently and they always have a 10-11% coupon floating around.
