U will get excellent results....the only draw back is the amount of injections....thats why it is such a good stack with fina(both have no esters and need to be injected frequently).....throw a small amount of fina in there....Fina/prop is a kick ass cycle....the best imo
depends on your cycle history. i know guys that have had good results from sust @ 250 a week for their first cycle so i imagine that 300 prop would have been better for them. i also know guys tyhat have had shitty results from low doses so it's up to you.
by the way fina and prop both have esters. they are short but they are esters. propinate is the name of the ester for test propinate and fina has the acetate ester unles you have some "parabolan" but then again i beleive all the parabolans these days are fake so i think they would be acetate also.
