Hauge, first off..you are welcome.

As much as an asshole I can be, I do like to help my fellow bros here (but do what's best for you, im far from being a guru or an 'expert' on this stuff)
And again, and im not 'anti-scale', since weight loss via scale 'tends' to be in tune with fat loss as well, and since DNP specifically targets loss of fat tissue moreso than muscle tissue when it comes to body composition (even though this shit affects any mitochondria throughtout the body. Boy, wouldn't it be neat if we can send some type of liposome laced with DNP to target fat cells directly, maybe that can be utilized in Lyle McD's plan killing fat cells

. But my theory is science fiction at best)
My point for scales was that it shouldn't be the measurement of tool to dictate how much fat one has lost, especially when it comes time for DNP. THat means if you lost 20lbs with DNP by scale weight, that doesn't mean you lost 20lbs of fat EVEN if it was maintained. After a few carb ups, and perhaps gauging by strength in the gym (if strength doesn't diminish, and you still lost weight, that 'usually' means you lost plenty of fat/little to no muscle).
The mirror CAN be a good tool or a BAD tool depending on how you view it. THere are different types of reflections people get with mirrors due to ligthling, distance, gloss level, etc. Im sure some guru who specializes in mirror can fill us in with that knowledge. Any "Mirrorologists" around here?
If you can be honest in your assesment when you look at yourself in the mirror, and you use the same mirror over and over , then I could see how the mirror might be somewhat of a useful tool. FOr example, if there is a girl who probably has a low bodyfat percentage (has abs, legs are pretty lean) but views herself as a fat ass due to psychological treatment while growing up or whatever it may be, then using the mirror may not be her best option. Some dumb cocky bodybuilder (I promise you there are no shortage of them around

) who views themselves as a gift from God who really has a too high of bodyfat percentage may end up too fat for a contest due to ego.
If the mirror has worked for you and you can be honest, than go for it. I use the mirror, the scale and most importantly body fat calipers to check where I am at. My bathroom mirror tends to give me an accurate 'real world' reflection, unlike the ones found in many gyms.
So do remember that when you are on DNP, you will probably look 'worse' DURING the cycle. Why? SImply because your muscles have been depleted of glycogen and your skin is holding a shit load of water, which is a great way to make your body look shitty. It's exactly the complete opposite what a bodybuilder wants to look like when they step on stage.
On contest day: Very little water under skin, muscles full of carbs
On DNP cycle: Little muscle glycogen, TONS of water under skin.
So wait about a week after finishing DNP to lose the water under the skin and to bring back some glycogen into the muscles.
Also, depending on where your body fat is, you will get all kinds of weird appearances in the mirror. Well, at least for me that is.
When my bodyfat is around 15%, I see NO results during the cycle, and very little a week after I finish.
AT 12%, I see little results on DNP cycle and typical result when I finish.
When Im around 9-10%, I see plenty of results that it's almost inspiring in a "Rocky IV" kind of way. (which ever Rocky was fighting Dolph Lungdren). When I finish, I shit in my pants with happiness. Even though I bloat, I can see my abs coming through nicely.
So just a reminder there in case you are wondering. Best wishes and let us know how that DNP cycle goes!
