Larger operations have employees that need to be payed thus higher prices, but those employees are also added risk as they can easily rat out if upset or busted where as a single person operation has no employees and can thus offer lower prices. This is the way I see it. I've brewed for a select few buddies in the past including myself of course and I've never cut corners and everyone was more than happy with what I gave them.
100 grams of test-p is $88 and say another $300 for 100 sterile vials plus another say $150 for everything else needed to make a finished product. That's a total of $538 from start to finish and If I charged $25 per vial minus the production cost that would leave me with $1962 for my trouble. Short esters and bases you can make a huge profit with little put in and larger esters like tren-e and nandro-cyp can still make a darn good profit for a single person operation. I usually brewed everything in 50ml vials for buddies so my calculations might be a little off, but if someone wanted to run a small op with low prices they could do so without cutting any corners even when it comes to labels. Those brother label makers make damn good clear ones from what I've seen here and I prefer the clear ones compared to the expensive ones most labs use, but I'm a simple man.
My point being to me price doesn't reflect quality, but I think the professionalism of the owner/rep does! If your rep/owner acts like a fuck tard and seems shady then chances are they are shady, but if they are prompt and caring then I think they would be the same way when brewing.
