No OTC PCT should replace a SERM. The products mentioned in here are great, but should be ran with a SERM. No SERM = no cycle in my book.
Once you have a SERM, my favorite OTC product to run in conunction with the SERM is AlphaMax XT. It is hard to beat its value and all of the benefits the product provides, especially during PCT. AlphaMax XT will help control cortisol, which is very important during PCT, boost libido and increase free test.
It 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.
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.
Forskolin can increase lean mass and increase fat loss.
AlphaMax XT also contains a full dose of ferulic acid, which has been shown to improve mass and strength, which is valuable any time.
