it is very different, they are not comparable.
Yohimburn uses a natural and considerably more effective delivery platform.
Yohimburn ES contains in addition to yohimbine and caffeine
Acetyl-l-Carnitine (ALCAR): Increased lipolysis via enhanced mitochondrial activity.
Acetyl-l-Tyrosine (ALTYR): Increased neurotransmitter and substrate availability, essential for extended lipolytic and adrenergic activity.
Histidine: Increased lipolysis, specifically in WAT (white adipose tissue) via peripheral modulation of CNS.
Theophylline: Increased lipolysis, "energy" and diuresis via cyclic AMP and Beta-Adrenergic activity.
Theobromine: Increased lipolysis, "energy" and diuresis via cyclic AMP and Beta-Adrenergic activity. May in some individuals cause appetite suppression and feelings of "satiation".
in contrast:
Lecithin does nothing for fat loss (the injectable lecithin works because it contains the detergent deoxycholate)
Sesamin has no local effects as is not particularly suitable for transdermal delivery, most of its effects are in the liver.
octopamine does nothing in humans, if you were an a rat it would lean your right out, but humans have very little beta-3.
synephrine is an A1, which really makes it mainly good for appetite suppression (a central, not local effect)
alcar-well looks like a small amount, but an good ingredient
ascorbyl palmitate is just vitamin C
