no reason to stack long ester test and sustanon. also Charger69 super sus is just a slightly different mix than regular, its not common, recently labs have been trying to trick people into thinking they have something new but just still with old school sus, i find it keeps levels more stable than regular C/E test. plus it has the added benefit of having short ester in it as well which give you alittle boost feeling the date of administration of it. to each there own. gotta love what labs are trying to do these days. all they do is make things alittler higher than the person next to them and use a better thesaurus when choosing a name for there new "blend"
