TweetTogether they are great. Can't see doing GH without it unless you are rich and don't care about $$ much. You'll need to use GH for months ...like 4-6 to see gains in size really. I noticed fat % dropping within the first month though, even doing slin (which most say will put fat on you). I'd say you should read the research out there (search this site) first before comitting to that combo.
