some placebo and some real. the way the herbals work is completely different than hormonal stuff so it makes sense. Thats sort of like saying viagra can't give you a hardon in 30 minutes because pinning testosterone doesn't. they work in completely different ways. You can feel ephedrine or caffeine right after you take it right? but can you feel T3 30 minutes later? no.
Placebo effect and stim effect can account for a lot of the strength part. metally feeling good, and if you dont usually take much pre workout stims, that can make a decent diference on strength and aggression feeling from right after takign it
