One option would be to stack two products, but you could also pick up one product that does both. Alphamax XT would be a great option as an all-in-one product that can help increase natural test levels and limit cortisol and estrogen levels. Alphamax XT contains a potent natural test profile including Mucuna Pruriens and Longjack, which have both been studies to increase natural testosterone production and increase libido.
Alphamax XT also contains a natural AI which can help keep cortisol and estrogen levels in check. It includes DHAA, which can help control the conversion of testosterone to estrogen, and Ashwagandha, which a is a powerful ingredient for reducing stress and improving recovery. To top it off, Alphamax XT also contains foskolin, which has been studied to help increase lean body mass while decreasing fat mass. Its a very well rounded and complete product that would allow you to stick with one product to cover all of your needs.
