as far as I know, there is no comparison to being on an all natural test booster, and steroids. (ph/ps/ds, w/e floats ur boat)
if your asking how does diesel test compare to other nat. T boosters, then looks like there is a general consensus thats its better than most.
but if you want to use it to "boost' the effects on a cycle of superdrol, well, personally think it's pointless. all the herbs that are suposed to increase test will do nothing to prevent your hpta from trying to balance out the uneven amount of hormones. i.e. becoming shut down.
