Yes, i am aware of that, i just couldn't find enough info on the subject. I am asking because their test prop is ridiculously cheap and for the amount i want to buy, i'll pay 30-40$ less than i would if I took products from a different lab.
I have friends who have run GP oils with varying degrees of success. One time it will seem like the stuff is overdosed and another time it won't really work at all. A buddy of mine ran 2 separate 6 week prop cycles within the last year. He uses only prop and calorie manipulation to cut. I don't remember the results BF% wise or strength gains on his lifts, but the first time he ran 100mg EOD and cut up really good. Ordered the same product from the same supplier a few months later and ran 200mg EOD and he said he felt "like he wasn't even on anything." That's pretty clear to me that their products CAN be good, but quantity is much more important to them than quality.
Their orals on the other hand are the best I've ever used...no joke. Especially the Oral Tren, that stuff put size on me quicker than I could have ever imagined. Doesn't work at all like injectable tren IMO. I don't think I could gain more weight taking Dbol, Drol, and Halo concurrently for the same 3 week time span that I took the Methyltrienolone.
