Clomid vs. Nolvadex: Core Components of Effective PCT


Let’s talk PCT—one of the most overlooked (yet vital) aspects of any steroid cycle. While many users focus on gains, post-cycle therapy is essential for restarting your body’s natural testosterone production and protecting long-term hormonal health.


Two of the most widely used tools for this job are Clomid (clomiphene citrate) and Nolvadex (tamoxifen citrate)—both classified as selective estrogen receptor modulators (SERMs). Though similar in function, they each play unique and often complementary roles in a well-structured PCT plan.

Check below for some useful info on how they work and when to use each:
