You need to stay away from DNP, alot of the info you have posted here about it proves that you know next to nothing about how it works.
DNP is stronger than anything on the market by a million miles, then a t3/clen combo, then clen by itself, then ec stack and finally albuterol/synephrine/yohimbe, etc.
The fact that you thought clen was stronger than DNP, and you haven't used any cutting drugs before, proves that you shouldn't be going anywhere near it.
Ephedrine is one of the best fat mobilizers around, it has the ability to get the fat out of the cells & make them available to be used for energy. In other words, its not simply an appetite suppressant - its a very good thermogenic.
DNP does interfere with how your body functions, and your body DOES adapt to it over time.
Again, you don't know anything about DNP so don't touch it.
This is complete nonsense, your metabolism is going to drop when your losing weight regardless of what compounds your using. Certain things accelerate the drop in metabolism (too much cardio, etc) but some drop is still inevitable.
As for people gaining weight afterwards, that's because they haven't adjusted their calories to maintenance properly. The compounds aren't to blame for poor diet plans.
Not a fan of this stack to be honest - chromium is overrated and there are better OTC alternatives to EGCG.
There is no such thing as a person who cannot get into single digit bf, NO SUCH THING.
There are ALOT of excuses available for you to use: my genetics suck, I was born fat, my metabolism is slow, my hormones are messed up, etc.
Its all complete bullshit.
As a beginner to cutting drugs, I suggest you supplement with a simply yet effective EC stack alongside a caloric deficit, adequate protein intake & training.
Also, please stay away from DNP...I know more than most people on here about DNP and trust me when I say you know nothing about it & your not an ideal candidate for its use.
This isn't personal, its just fact
