I've been taking trenbolone for the past 6 weeks and I've experienced on the fourth week my ass swell like a grapefruit and it was painful like I got a charley horse my friend told me my ass was saturated and I should do it in another muscle. I've tried in the shoulders and I've experienced a small swell and small pain but sweating like a pig and hard time to sleep. What is it exactly normaol or bad batch.
