dude, put 2 mls of bacteriostatic water into the vial. Pull back on a slin pin to the .1 mark. that will give you 250 MCGs of hcg.Some people report good dosages m/w/f at 250 mcgs, while some others will report 500 MCGS is good enough 3 times a week. 500 would be at .2. 5000 / 2000 = 250. Hope that helps
