Letrozole

This can also make it appealing for low testosterone treatment, but it’s often not enough. However, for PCT purposes, while it can be effective it’s generally not recommended. The primary purpose of PCT is stimulating natural testosterone production, which Letrozole can do very well. However, part of the purpose of PCT is also normalization, which will be difficult with severely suppressed estrogen levels. Estrogen is an important hormone as it promotes a stronger immune system and healthier cholesterol levels. For the anabolic steroid user, his best bet for PCT is sticking with SERM’s for his natural testosterone production needs.
