Symptoms of test shut down/severe suppression
If you are doing LGD without a test base, you aren't going to have a good experience. At week 3 or 4, you will feel like a piece of crap... And still have to PCT. 4 Andro, EPI, or Trest should be used in conjunction with LGD. If not, don't start... My opinion.
I did a 12 week run of Trest and LGD. Got great gains like 15 pounds LBM, and no shut down or suppression sides. I had a bit of trouble in PCT but held all my gains for most part. Next time I'll be 4 weeks of Clomid/ kings blood and 4 weeks after with another shot of kings blood.
