Hello guys. I have a situation and I hope you can help me or give me tips. I started using testosterone (first contact with eas) 4 months ago. I started with sust (250mg/week) and I felt great on the first 6 weeks (weight gain (11lbs) / drive / high libido) and then I started to feel some side effects. From the 6th/7th week on I started to feel headaches, tiredness, blurred vision on the next two days after the test shot that would improve within the next days. I lowered the dose and I felt better but instantly I lost weight and size. I tried to change to enanthate, and increase the frequency injection but I could never reach to that same dose again (just 250mg week) because I would feel all the side effects I listed above. Do you think it could be related to estrogen? I never felt sensitivity on my nipples, none at all. Do you think I should keep the test dose very low and add another compound? What do you guys think? Thank you. By the way, I'm 30 and my weight is 81kg, 12% bf.
