I am sorry to hear about your issues. I am unable to provide an accurate assessment without knowing the full details of your medical history and performing a full physical exam, including a genital exam. I strongly encourage you to schedule an appointment with a primary care physician
to further discuss your symptoms. After a thorough in-person evaluation, this provider can make recommendations on the next most appropriate steps.
In general, supplements, including epistane, have very limited regulation by the FDA. Many supplements do not contain the substances they claim to contain. Additionally, there have been many high profile cases of supplements severe to severe reactions, including death. Testosterone supplements have a theoretical link to increased risk of prostate cancer
. In addition, recent studies have linked them to an increased risk of coronary artery disease. As such, I strongly encourage you to discuss these concerns with a primary care doctor
It is unclear from your question what effect this supplement is having on your testicles. The change in color suggests a change in the blood flow to the testicles. Increase temperature of the testicles can lead to a decreased sperm count. The increase movement may be your body's attempt to further regulate the temperature of your testicles. You need to discuss these concerns with a primary care doctor.
