Stims / Thermogenics
I see you are asking some interesting questions here. I have used stims & thermos for a very long time.
First lets start with the Grand Daddy of them all.
Mini Thins EI 25 mg Ephedrine + guafeinheusan or however you spell it not gonna take time to look it up. This was the first major stim I ever used and man it used to get me sweating so bad it was insane. I have even gone so far as to crush a few and snort them in my much stupider days. I have taken up to 100 mg of ephedrine at 1 time and boy was that fuggin stupid! My balls hurt for hours. Not only did this keep my hunger down and energy through the roof it made it virtually impossible to eat the nutrients that I did want to eat as well. Yet it was ridiculous for fat loss. Was not good for Mr. Wang though, he would become shy and introverted. Did not want to come out and play, even though I was hot and sweating it always seemed there had been a cold draft in my pants... Also even at a young age higher doses of this would mess with my prostate. I did not know what it was then but I do now.
Fast Forward ephedra gets the shaft, and the next really good strong stim I was able to find was the second generation of HydroxyCut Hardcore with the Liquid Release capsules. This stuff was insane, 30 minutes after taking 2 caps I could have rocketed to the moon on just nervous energy alone. Was very effective as far as thermogenics but also made me fill ill many times from being overstimmed. The excessive use of caffiene just did not agree with my stomach.
Moving along - Next I got my hands on some sublingual yohimbine, holy heat wave! I am not sure if I have ever really been this hot from only taking 1 dose of anything. Unfortunately it was also characteristic of too much Y-HCL being delivered at once it made you down right sick to your stomach when taken on an empty stomach. However once learned how to avoid that reaction it became one of my favorites then the store I was getting it from stopped selling it.
I don't really remember too many of them for a couple years. Nothing really struck my fancy, I used them but nothing that made me remember them until I guess about 4-5 years ago it seems when I found Anabolic Xtremes StimulantX this was my stimulant / thermo of choice for over a year. I tried a few others but almost always went back to this one. It was probably one of the strongest stimulants I could find and really helped me not to eat unplanned meals. Body temp went up good and I always had good results with them.
Now we land to a time where I began to really pay a lot more attention to the supplements I was taking. I have tried several over the past few years since then however I will only touch on my favorites that are specifically thermogenic.
Once I started studying more regarding all the ingredients and what not I found that I still loved Yohimbine and I still say it is probably the best thermogenic source of heat out there. Whether it is Y-HCL or Alpha Y, Yohimbine is where it is at when you want to add some real heat to any diet product. When I wanted to run low stims I would have Recreate and a 2.5 mg Y-HCL pill 2 times a day and I was in heat heaven.
Next - Ban on Ephedra had been lifted for 2 years but no one selling it anywhere. Insurance to high to carry it as a product... No wait a minute. Hi-Tech Pharmacueticals has some balls. Stimerex- ES a combination of the Stimerex version they created when Ephedra was illegal in order to burn fat with 25 mg of ephedra added. Oh yeah and 2.5 or 3 mg of Y-hcl. I would just sit there and drip sweat, no activity just sitting there at my desk as beads of sweat would grossly trickle down my armpit making me realize I desperately needed an undershirt. This is honestly one of the Strongest and best Thermo I have had to date. However due to the ephedra it was still hard to eat when it was time for a feeding.
So I think you can see that I am leading up to the newer products. So let's mention OEP, and A-T2, both of these products are excellent but I have to give the tip of the hat to A-T2 regarding the thermo effects. I am sure the has to do the the 3,3 d in there. I just traded some other supps in order to get some Shift so that I can run that with my home made transdermal that I have 5mg Raspberry Ketones and 6 mg of Y-HCL in. This stuff it a rub on furnace.
I really enjoy adding A-T2 to a preworkout, or some recreate and feeling a great burn. A-T2 is great to me, it heats me up enough that my hands start getting a little cold which has always happened to me with any really good thermo / stim. Either they sweat a lot or they get very cold while the rest of me is hot. AT-2 and OEP both made me sweat, and or get cold hands. They both made me sweat buckets, and I was able to eat when ready with them. It was not a fight to choke down the food.
Fast Forward to Now Dexaprine in the house! Dexaprine really has me pretty impressed. They really did a great job with this pill. One pill is enough for all day and never is it overpowering but I feel warm all day. Energy doesn't really dip at all and the appetite suppression from it is excellent but once again not so stimmed out that eating the meals I want to eat is a problem. Out of the ones I have had recently I have to give a big not do Dexaprine, I can not say how effective it will be as i continue to use it. I just started about a week ago. It has the non stim thermos of the 3,3 and 3,5 to stimulate thyroid and is really good so far. I haven't taken it long enough to speak to it's ability to actually drop fat however I am very confident in that ability due to how I feel on it.
