Hey man first of all just a rule of thumb here we appreciate all your stats, age is one, but we like body weight, body fat, height, goals, items you have on hand, we just gotta make sure you're doing what's right to stay healthy. Generally hcg is used in the last 4 weeks of your cycle BEFORE starting pct (clomid, nolva, aromasin, throw in some gw and mk 2886 for fat control/anti catobolism) at 1000ius every week. If your bottle comes in 5000 ius then just run it at 1250iu every week. I don't believe that should hurt you.
