I'm a stim junkie at heart so here is what I do and it's worked for me. I use 3 different products. Ignite 2, stimul8, and alphamine. I use ignite 2 by itself, the next day I use Stimul8, and the next day I use a half a scoop of each. And then I start over. On non workout days I have a cup of coffee(non workout days are Monday and Thursday). About 2 pm everyday I have a 3/4 scoop of alphamine. I've only cycled off the alphamine and that's because I use it everyday. Been doing this for months and months with no stim issues. If and when ignite 2 or stimul8 start not having an effect I'll cycle off. BP and HR are normal and that's even while on cycle too.
