In the past month. I've had great luck with REDuction by controlled labs. I bought it when it was on sale at nutra for only 20 bucks just to try...It was a helluva deal for the money.
It gave me an overall good flow of every throughout the day without any jitters. Apparently the 200mg of caffeine that is in the red morning pill is time released and is slowly released throughout the day. It seems to work well as far as energy.
The pea in the morning pill also gave me a noticeable better mood too! ...At least for the first week or 2, and this seemed to diminish (i'm not sure if you can gain a tolerance to PEA, but thats what it seemed to do for me).
With HELP from REDuction...i've seemed to maintain my 200lb weight while reducing my bodyfat a 2-3 percent. But there is no way to tell the amount of these gains i can contribute to REDuction alone- because at the same time of starting this supp, I began a very strict diet and workout program as well. (with much cardio)
I believe the diet/workout program had more to do with my results-but REDuction sure aided me as far as energy and a better sense of well being in the first couple weeks.
Although this is not a fat reduction product per se. I highly recommend drinking muscle milk while trying to do a clean bulk. A friend recommended to me 2 months ago, and I swear by it!
I use muscle milk as a meal replacement and it does a great job for curbing my appetite and giving me a well balanced meal thats convenient to take anywhere. I believe the constant use of muscle milk as meal replacements (at least 2 a day - 1 scoop each meal/just a half serving, with 12 oz of low fat milk will do the job) will really help maintain a lot of your muscle while keeping fat down.
If you want a really noticeable energy/fat loss supplement without worrying to much about a diet - ephedrine/caffeine always works too

Not sure how good that would go with a bulk tho!
Hope my experiences helped.
