I’ve used a brand that’s not listed here years ago but can tell you r was tested and there still going strong for years. I ran it long time ago though when I had much stronger ci trio of my emotions and temper and didn’t get such harsh sides like I do now. But I remeber it was dosed at 5mg/ml I believe. I started at half ml on workout days. It was never a staple in my cycle. It was an addition for a boost . That strength /aggression/alpha feeling kicks in asap!
Never had that feeling. Mine was always a get shit done feeling. Nothing can get In the way feeling. Feel good feeling. Love the stuff. Has to be injectable though. The 500mcg orals don't quite pack the same punch, and I never expected them to. They are decent though
