PSL has it and I just posted some pictures the other day with it, it is used by a lot of hardcore individuals and it can be extremely successful if use properly.
It is not any more dangerous than running testosterone or anything else, the only difference is you have to be more cautious and you have to have a strict and dialed in protocol when using it.
People use anti-estrogens all the time with testosterone, it's not anything much different just more timing and more frequency with anti-estrogens.
My suggestion would be to start off low and use 50mg every other day, and you do not need high testosterone with it in fact I would use testosterone propionate at a very low dosage 35-50mg every other day.
PSL has had it Mass spec tested,
It is best to be used for 6 weeks and there's no point in using any longer because I noticed the gains do not have any greater returns.
If you're looking for a quick blitz blast cycle to get you through a brick wall this is the way to go.
You will need to use arimidex at .5 or 1mg everyday, but my suggestion is to load on your anti-estrogen a week prior to using. Do not increase testosterone and you do not need to use any other compounds with it.
If you stick to this protocol and you have a bad experience then my next cycle is on the house..
