Yes, and AI is an anti-estrogen. You are using nolva which is effective for LH stimulation and gyno prevention but it will only protect selected tissue in your body from estrogen (such as chest, lower back etc). Even though you are using nolva your overall estrogen level in the body may be undesirably high.
This is when the AI comes into play. The Anti Estrogen will lower overall estrogen levels and increase test levels. This will bring your test/estro levels into a more favorable ratio and eliminate the bloat, decreased sex drive etc.
No keep in mind that even with and AI your sex drive won't be like it was on cycle or before..... you just need some TIME and REST. Keep training hard and heavy, but don't overtrain. After 6-7 weeks when you stop the clomid and are just using and AI, you will start feeling like your old self again.
Not to get real personal here, but I noticed my balls actually "filled" out when I stopped the clomid. The clomid worked phenomenal but I didn't notice the recovery effects of it until after I stopped.
Good luck bro
