I have been workin out for awhile and have been taking tes250 for about 4 weeks now with about 2cc's a week. I have noticed some great gains but one thing I did notice is i have been waking up a lot at night with my arms asleep and im not sure if this could cause lack of blood flow or what the delio is. Maybe its just me wondering what is causing this and im over reacting. I thought about doing test for over a year and after doing some research finally decided to give it a try and defintely feel great other than that. Anyway Any suggestions would be helpful. Thanks!
