i dont understan why you would want to make susta? susta is good for hrt thats why they made it with multiple esters but for bb:ing a long ester like cyp or enanthate is enough

Even for TRT, single long ester testosterone is superior to Sustanon. The theory was that Sustanon would provide more stable serum testosterone levels but in practice that isn't true.

Now testosterone does have a good bit of testosterone decanoate in it. For people that like longer cycles and that prefer to inject less often, testosterone decanoate may make sense. But those people should just use testosterone decanoate, not Sustanon.

Yes because if he wants it to "kick in "faster he can use propionate mixed with enanthate or cyp the first weeks before bloodkoncentration levels build up from the long ester so maybe a mix of prop/enanthate but 4 esters no

Sweden ay? Nice
