My favorite product like it of all time is 5alpha test. And im not saying that because I rep for them its really is but that being said I don't want to try to sell you on something. Between those two I prefer proto and ive run it up to 250mg 150 is probably the sweet spot it really did not do much of anything more above that point. I am a giant fan of DHT metabolites in all honesty though I just response rather well to them and have almost zero sides.
