You will probably get a better non biased response about 1 test on the supp board, I doubt the majority of people here have any experience with it. ProH's, in my opinion, can't compare with gear. They share alot of the same side effects and don't seem to give as quality gains, or that much for the prices.
However, I think 1 Test and 1AD are good products. I had the best results using short, 3 week cycles of 1AD at the recommended dose. I did find that my 1AD cycle gave me some heavier lifts than my last cycle did, but it shut me down hard. I mean really hard - hard enough that I'll never do another proH cycle again. I ended up gaining around 6lbs and retained maybe 3 - for about $70 bucks (1AD + some anti E's).
I think 1Test and 1AD are good if you want to keep "legal", but I'd pick gear over proH's anyday. The drug detection times are alot different, I'm not sure what you mean by that. I highly doubt the effectiveness of tribulus, and I don't think it even shows up in drug tests.
