I have been a BSL supporter from the beginning. I still have a bottle of your transdermal carrier, do you think it is still good to use? It has been kept indoors in a dark closet for about three years. Thanks!
Pour out some of tha carrier, add some active (yohimbine) and try a small test area. If it's systemic you ought to be able to notice some effects. IE: increased heart rate
If it's Sytenhance, your guess is as good as mine. Use it and hope for tha best.
I believe its from the dawn of transdermal carriers. High foluting sytenhance stuff didnt exist then. Its systemic, no doubt.
