Even on a purely oral cycle, there is suppression, although it is weaker than with testosterone. After a similar cycle without PCT, my testosterone dropped to 8 nmol/L, my mood was bad, and my erections were weak. It is better to do a light PCT: clomid 25 mg for 3 weeks or just tamox 20 mg for 3 weeks. I read a good guide for beginners https://steroid-shop.com/beginner-guide-to-post-cycle-therapy – it explains exactly these cases when the course is light, but you still need to recover. Don't take any chances; it's better to take it for 3 weeks than to suffer from low testosterone for half a year.
