Hmm, wonder what it means exactly.  Perhaps just a localized irritation.  You may very well be on the cusp of tanning.  Fingers crossed.

wiseguy 954,
Thanks for your instant message, I thought it important to answer in the thread. The question asked about taking it internally.  
The highest over the counter concentration I've seen is 20% recommended dosage, one capsule per day. I don't believe this dosage would do anything to give you a tan. Forskolin is a very powerful herb, do some searches and read about it on the web. I believe that taking large doses of this could upset many of the normal metabolic processes in the body which could be very harmful to you if not deadly.
Think about it- the researchers could have just fed it to the mice, Obviously they did not and choose a topical route for a reason.

Socialguy:
I'm going to start another test in november building on yours.  
I am researching the purchases now.

Astralagus has been used for a long time for vitiligo?   Do you have any references?  Sounds interesting; but, I can't find good science info.

High oral dosing will do nothing but give u BAD diahrrea. I ordered 500g of the 20% extract a while back, and was using it for allergies and to try and increase cAMP (to aid fat loss), and would always stop 2 weeks into cos it was giving me the shits (literally).

mel-man, where is that board at that they were talking about those high doses internal.

Mel-Man,
These people that reported taking Forskolin orally and getting a tan, were they confirmed Fitzpatrick type I? Remember a type II or III could get a tan with sun exposure regardless of what they took. I still believe if it were so easy to tan a type I by oral dosing the Dana- Farber researchers would have just fed it to the mice. The Forskolin may be changed in the digestive process or the dosage required may be so high that it would have killed the mice. Also, the mice darkened without any sun exposure.

Here is a link to the other one.  This poster gives less details but I've read his other post and he is definately experiece with Forskolin.  He uses the 95% extract and seem very knowlegeable about helath, supplements, anti-aging, etc
 
Here is the cut and paste from the one of his posts:
 
"IME just take a high dose oral and you'll get tanned, no need to go lotioning yourself. it gets really annoying after a while. I was applying like 4 different transdermals during my cycle."

Mel-Man,
I went to the sites you posted, but it still doesn't answer the question what skin types are these people Type I,II,III.?
Type II can tan slowly naturally, Type III can tan easily with UV exposure, but Type I never tans! Unless there are controls and all the facts, as they say in court " objection your honor hearsay".
The member," the big B" on that site posted a link to 2002 study on the effects of Lipoic acid acid and Resveratol on tyrosinase activation in pigmentation using an "in vitro" study, in a test tube and on swine skin "in vivo" study. on a living creature {but applied topically} which confirmed that Lipoic acid and resveratol did inhibit pigment formation.
This was good info, I take Lipoic acid daily, so it could have some effect on my results.
Then go further and read the post by Elrond "Director" Oct 20,06, he also cautions about taking a cAMP modulator in large doses since you don't know what other effects it can have in your body metabolism. Grateful for all the info.

The difference is forskolin cranks up cAMP systemically.
There is no evidence that vitamin D does that, just that
it enhances the system at the skin level.
