Honestly..... I would probably just stick with 300iu's twice a week...... it'll be easier to measure too.
1ml of solvent will equal 1500iu's/ml - each slin pin is marked every 10iu's. Each 10iu marking would equal 150iu's. Pull it up to the 2 marking and you've got 300iu'sof HCG.
As big said.... theres a lot of ways to doit.....
