I just picked up a USA grade 5ML HCG 2,000 U / ML bottle already mixed HCG I want to run with my Tri-Tren blend. My buddy who sold me this said it is very potent and to only take .1iu Monday, Wednesday, and Friday. Is he correct? Because he made it sound that every 1iu is 2,000 so you want to take less than that. I just want to make sure I take the correct dosage and not burn my nuts off since this is new to me this pharmacy grade and how long will my dosage last with this bottle?
