Maybe you belong to the happy people that respond to cyanotis vaga 90%+ dosed at > 1,5g. I definitely do and you can get it pretty cheap. I went up to 3g and it was pretty nice.
Another decent choice is Turkesterone (Tonvara). I only tried it at 4 caps, but I will report my next run at 6 caps per day. Good results at 4 caps.
I also had RCE at 10:1 and I am currently experimenting with plain Maral root (very easy to get). I drink it as tea and eat the used powder at like 10g. It is just crazy how good I feel on this stuff.
I definitely respond positively to all three sources. Using a high protein diet and consuming it around meals, I look more massive, recover more quickly and get stronger. For me, it is a staple. One of my favorite supplement and I try to change + diversify my sources.
Strength gains are better than for ArA in my case. And also look more pumped. I am currently two weeks in using PA, ArA and Ecdysterone (using Maral root). We'll see how it goes
