GHB makes an excellent alcohol replacement. Dose is dependent on bodyweight and stomach fullness. The common dose for partying is within the 3-5g range. Starting low and working your way up is recommended.
GHB also makes a good sleep aid. Again dose is dependent on bodyweight and stomach fullness. The usual dose is around the 5g+ range. Sleep patterns can change if GHB is used for prolonged periods to sleep though. I wouldn't use it every night to sleep. Only nights where there is a time constraint on your sleep or times when sleeping is a real problem for you.
GHBs bodybuilding uses are a highly debated subject. Some argue that the GH release is significant enough to cause muscle growth/fat loss. I for one don't use it as a direct bodybuilding "aid". Indirectly I guess it is an aid as it allows me to avoid alcohol, which in my opinion is more harmful to the body than GHB...
Thanks bro. I'm mainly interested in the alcohol replacement idea. I know I should be disciplined and not need anything, but I do like going out on the weekends. Great post.
