Just curious as to what doses you use, and if you're taking all of those at once. I really enjoy moderate amounts of DMAA and caffeine, and I've used Armodafinil alone before and liked it, but all 3 together seems like it'd be a bit much.
I worked my way into them together. Not all at once, at first..
I started with just Armodafinil and rotated EOD with DMAA. After building some tolerance, I started taking Armod w/ caffeine. Then added DMAA in low, low doses (like 25mg). From there, I started using the blood pressure meds just to be safe. Never had any issues, other than taking too much DMAA and having recurring crashes throughout the day (really crappy lethargy, multiple times per day when you take too much DMAA).
Truth is, they are all benign until you increase the dose of DMAA. DMAA at 50mg, cake walk. DMAA @ 150+mg, really high for a good two hours then subsequent crashes over and over, until about 12 hours later.
But every now and then I took:
Armod - 150mg
Caffeine - 120mg (drank a crystal light packet. Sipped as I did morning fasted cardio)
T3 - 25mcg - this just speeds up the process for everything to kick in but doesn't amplify it in a sense. Instead of taking 90 minutes to kick in, it takes 45 minutes instead.
L-Tyrosine - 1000-1500mg, occasionally 2g
DMAA - 50-100mg
Another great one that is much, much cleaner is subbing out Armod and DMAA w/ Yohimbine. But that fat burner works differently than the other two and targets a specific type of fat, so I usually take it intermittently anyways.
But from my experience, a single dose of Clen is potentially MUCH more dangerous than all of that stuff combined. Just 20mcg too much of Clen can take you from a fat burning zone to digging around for Beta blockers, blood pressure meds and considering going to the hospital for services.
The best compromise for all of this has been Ephedrine and Yohimbine, both in lower doses. I do not recommend this, as I'm not even 100% sure on the scientific literature whether they can be done safely, but from an anecdotal experience, they get the job done very well with very little:
Ephedrine - 12.5 - 37.5mg
Yohimbine HCI - 5mg
Caffeine - 50-200mg (depends on sensitivity)
L-Tyrosine - 1g
Kills appetite and burns fat. Turns eating into a task rather than a hormonal response to a need.
