I have used all 3 from rui and have been pleased. In fact they have been my go to on all 3 for the last few years. My go to on albuterol and nolva for even longer than that.
I just switched to their stane about 2-3 years ago. Before that I was using their adex for my ai. Took a bit to dial in my stane dose (almost gave up and went back to dex) but once I did I havent looked back. STane is a very forgiving ai and I now love it.
Also I love albuterol btw. Once I tried it I have never touched clen again. It is slightly less effective than clen for fat loss but man it is so much more pleasant to use. The sides are manageable and I can sleep well at night due to the shorter half life. I even use albuterol as a pre workout from time to time if I am dragging. It makes me feel great, not jittery and nervous like clen.
Hope that helps!
