Adwords ?
 

I am running some tests on adwords, getting some decent clicks at much much lower CPC.
would love to compare notes with you if you use adwords. [ this is mainstream project ]

Comparisons would only be valid if you're comparing results in the same niche. Also, differing ad copy text produce differing CTRs.

You can also try adbrite and avnads.

I am testing a test run on Green tea, weight loss. I am getting clicks for anywhere from 0.05 to 0.12, with a decent 14.12 CTR. but still volume is less. trying to see how to incresse the volume.

you have to look at what if any competition there is, see how they rank, adjust bids accordignly and add keywords. Ultimately google decides how much and how often to run your ads
