BroGator I just finished a 7 week cycle of LGD. I was planning on going a full 8 weeks, however, the lethargy was bad at 6 weeks and I pushed through to 7 weeks. I stopped seeing any benefits on week 7 and barely felt like going to the gym. My joints, mainly elbow and Achilles were extremely sore. I started PCT this morning. My first 4 weeks were 5mg and the next 3 weeks were 10mg. I gained 7lbs, not all muscle, but definitely saw an increase in size and strength. 8 weeks may sound good on LGD, but it really made me drag ass and no matter of sleep would fix it. Just my two cents.
