I took a 5ml syringe /w an 18G needle and filled it to 3ml then pushed it back to 2ml to make sure all air bubbles were gone.Then counted drops from 2ml to 1ml.I counted 70 drops.So at 4mg/ml I divided that by 4 to get 1mg dose which was 17.5 drops.Using a rule of thumb of .25mg for every 250 mg of test used I just halved that dose to get the .5mg dose I would use during my cycle which is about 8 drops.Is that about what you all are using?It didn't sound like much.......
