ok i know the difference within the esters between the two and prop is shot ED as opposed to two or three times a week for cyp... since prop is shot ED the blood levels are more stable than with cyp... how much different, i know everyone reacts different to the gear, is prop in the case of side effects... i heard ppl get no acne while shootin prop as opposed to cyp. does that also go for gyno? basically i was just curious how much different prop is than cyp according to sides ppl get in general from the two
