Also for any new guys to supplementation who live in the US. Since ephedra/ephedrine is illegal to sell as a dietary supplement you can no longer buy it.
Fortunately they sell ephedrine in the pharmacy behind the counter still. It is sold now as a bronchiodiolator or asthma aid, which is actually one of its legit uses. It is regulated, you have to give your license in order to purchase. They track to determine if people are trying buy massive amounts to make Crystal Meth.
You want to look for Ephedrine HCL..this is sold as "primatene tabs" it is a brown box. CVS and some others make a generic. Same ingredients ephedrine HCL at 12.5mgs mixed with guafanesin which is a sulfate and mucus thinner..it not toxic so no worries. If you can't find that version then grab BRONK AID by Bayer. This is Ephedrine Sulfate. Although not as good, it still works and those tabs are 25mgs each pill. A small box of either will run you 5-10 bucks.
So grab a box of these, and use 25-50mgs total. At the very same time take 200mgs of caffeine minimum, you might go as high as 400mgs if you are not stim sensitive. Then add in 100mgs of aspirin or so.
This is simply creating the beloved now illegal ECA stack. It is very safe and super effective for energy, weight loss, thermogenesis, etc..
Ephedrine opens airways, acts as a stimulant. Caffeine another stimulant. Both induce a faster heart rate and increase energy and heat in the body. The aspirin portion thins the blood and allows nutrients to be transported quicker.
The combination creates a process known as "synergy"..It becomes explosively more powerful due to the mixture and the chemical reactions when you mix these 3 it creates a super power, compared to if you took any one of those on its own. It can be used 30mins prior to workout for energy and strength gains. ECA stack can rival pretty much any of the latest and greatest preworkout supplements.
If you take it in even increments during the day, say 12.5mgs ephedrine, 200mgs caffeine and 100mgs aspirin, on an empty stomach say every 4th hour for example or 4 dosages, it will assist in fat burning and will give your body a better overall benefit for low grade energy gains and consistent fat burning.
