I truthfully think "loading" and micro dosing is a complete and utter waste of time and money. In my experience of tril and error, i've come to conclude that the most effective way to use MT2 is to simply dose it before you plan on tanning. I think that 750mcg-1mg is also a preferable amount to take. Obviously this depends on how severe you experience the nausea. I personally get little.
All loading does is give the body a lot of melanin that it has no way of expressing other than... freckles and moles. If you get a small amount of sunlight when loading (day to day commute etc), it will tend to give you even more.
Micro loading seems to give the body just enough to tan a little, but not enough to significantly tan. freckles will appear faster than the tan at this rate.
I've tried it all. Now i just take 1mg on the day i plan to tan in the morning and that is it. I get much less sides, and way fewer moles and freckles than before. I also get darker much faster and deeper.
Maybe on the first session of the yea ror so i might take 500mg instead, but usually 1mg.
However, please remember, that everyone is different. Our genetics are what ultimately decide how we react. Although I am a type 1 with freckles naturally, I don't get many from taking MT2 this way. It may not be the same for everyone
I hope you take some of this advice and save yourself a considerable amount of time and money.
