I have just used MT2 and I can tell you it is very effective!.
You need to start off slowly with it, i took 500mcg the first time and went bright red and felt sick pretty much straight after the shot.
My advice, based on my experience would be to start at 250mcg and slowly work up to 1mg a day, once you get used to it the sides subside.
Recently, after a few short experiment in the UK on sunny days (we don’t get many of them) I went on holiday to the Dominican Republic. The day before I left I took 300mcg, the next day 400, the next day 500 etc all the way up to 1mg in 100mcg increments.
The tanning results are ridiculous, you need only a few minutes of direct sun exposure for the MT2 to work; but you do need exposure, its nowhere near as effective without sun.
I have now come home and look ridiculously dark, much darker than I have ever been before, so much so its raising eyebrows everywhere I go. In hindsight, i recon next time I go on holiday I will drop to 500mcg EOD. on a plus note, I did not burn at all, my skin didnt turn red likle it usually does, it just went brown.
FYI the increaed libido side effect is also real so be warned if you are thinking of going up to 1mg a day, you’ll spend several hours in the evening with an iron rod in your underpants and your oter half will get fed up with you pestering her!.
