Have you tried Opti's GH? I was on SA GH for 3 months or so but between CNY, shipping issues, and some other problems I had with my last SA order I decided to switch to Opti GH. The difference between the two is night & day. Within a week of switching I noticed a huge difference at the same dose. On Opti GH I'm much more vascular, sleep like a baby, feel healthier, skin and hair look better, etc. On SA GH I was bloated and I didn't get that sweet GH sleep effect either. I didn't notice much of anything in the "feels" dept and visually everything changed quickly once I made the switch. I've been on Opti GH for a month now and I suspect I'll be on it for the foreseeable future.
I was checking out the Lobster too. I suspect their GH is comparable to Opti, as they both seem to specialize in GH. I think Opti is also a little less expensive. The only thing right now is Opti is sold out on his blue tops and grey tops.
