If you do try a brief cycle, say 5-7 days, my advice is to do it on a week when you have not much going on personally and professionally. It is tough on the body, even at 200-250mg, and you will not be on your A game after about day 2. I've done a handful of DNP cycles was constantly tired and even nodding off at work. Prepare to drink a lot of water and crank up your AC. And if you do try, yes is it smart to stay at 250mg and really lower dose longer cycles is safer than double (or triple, which I believe is madness) medium length doses.

Test, real GH, and other gear/peptides I believe are healthy when used in a reasonable and informed manner. I'm not so sure about DNP, though no doubt it works.
