i kind of dont like the fact that it came in capsules , but ive heard arimidex too coming in 1mg casules , which kind of turns me off towards it , but i would recommend that if they are in that size capsule , if u are for sure they are legit and not maybe , or underdosed , id either take the whole thing if u have enough , or do what u thought , open it and split it as best as u can . maybe if u have any other type of capsules that u dont mind wasting (like a vitamin u dont use ) open the cap , dump out the contents , and then put the dose of aromasin back in the empty vitamin cap , i personally wouldnt recommend that u just put all the powder in your mouth and drink it , or mix it all in a glass of water , id either take the whole cap or put it in a new cap
