no problem wuji.
piston, i've never heard of that so i can't comment on it. i do what the more educated people say, like swale for instance. he says 250iu/2x/wk, that's what i do, no questions asked. a doctor in endocrinology or a buddy at the gym - seems like a simple choice to me. as for your 5000iu's, if that's all you have - IMO, i would mix it with 2ml's of bac water, preload all of your slin pins to the 12th tick mark, which gives you ~300iu's per pin. two of those per week should last you right around 8 weeks. i would suggest utilizing them during the last 8 weeks of your cycle before post cycle therapy starts. reason being, once you mix the HCG, i've read it's only good for no more than 60 days. this is why i don't like 5000iu amps and why i choose 2000iu amps. if you were to draw 250iu's per pin, you would have 10 weeks worth but i'm not sure if the last couple weeks would have avoided degradation. 8 weeks = 56 days. again, this is just what i would do. if someone out there has a better idea, please chime in.
