andstonon - bioizer pharmaceuticals

im just starting a cycle of andstonon from bioizer pharmaceuticals
contains;
40mg test propionate
50mg test phenylpropionate
60mg test isocaproste
50mg test enanthate
100mg test deconate

anyone used this before or know how i should take it?
cheers

i understand the basic idea of using multiple esters of test but it is none the less moronic, why not just use a simple single ester so you can better calculate ur levels of test?
