Early AM pre workout

Looking for an early am pre workout. Not necessarily pre made.

For context, I workout at 430 am 4-5 days/ week. My calories were 2400 (maintenance around 2700) during diet/ cut. So far in total, down 23# from October. M45 5'-10" currently 176#. Recent dexa scan today I lost 6# fat and 4# muscle in last 4 months. My protein is 190-200 daily.

I'm not the one who wants to blame low T right off the bat. I believe some, if not most muscle loss, might be attributed to intensity. I'm looking for a decently clean, low caffeine pre workout for anyone else that does early am workouts? Anyone have experience with Vitargo S2 powder with cold brew coffee? Are there any other self made stacks/ whole foods you use? Looking for a medium carb/ low-mid caffeine quick digestion.

On a positive note, my visceral fat is down 40% in the last 4 months, so I'm not disappointed at all, just looking for a quick pick me up in am for performance, without the heart kicks.

Thanks
