I have done two tren only cycles. The first time it was at 75ED and I was astonished at the strength gain. The second cycle involving tren had a little test in it, so lets discount that one, although I did bump to 150ED for a bit. I am just now off of a ten week cycle of fina at 75ED for the first six and 150ED for the next three and finished with 75EOD over the last ten days or so. At 150ED you WILL notice a difference from 75ED. I feel a little funny at 150ED. Not bad, really--just edgy. The fat really starts to disappear at that dose if you diet, and the strength gets crazy, but there are cramps and such to deal with. Not to mention the night sweats and overall chemical odor you will have. After three weeks of 150ED I am tired of fina altogether, and GHB becomes MANDATORY as a sleep aid. This, in turn, necessitates a prolactin inhibitor of sorts (I use chasteberry). Fina at 150ED is a unique experience, and will absolutely transform your physique. However, when you disconinue (especially if you run it alone) the cyborg look will vanish very quickly. You won't look bad, but you will feel like shit. The look doesn't stick with me the way a winny look seems to stick. I find that the two drugs together, fina/winny, give the best overall cosmetic adjustments to my body. BTW, do not look to fina to put on serious size. You will gain weight initially, but the best characteristic of fina is the fact that it is THE ULTIMATE anticatabolic, and therefore is tailor made for dieting. It is NOT as effective as test or drol for mass building in the presence of excessive calories, but it is SUPERIOR to either for mass building on limited caloric intake. All in all, fina is probably the best bang for the buck, and you won't really know this drug until you hit it at 150ED, for a couple of weeks anyway, just to see whats up.
