So I've been doing a lot of reading on this and other forums about steroids, but one thing I've not seen is an explanation of why certain steroids are the mg/ml they typically are, for example why is Test commonly 250-300 mg/ml, where Tren seems to be usually 100 mg/ml? Does this have to do with the amount that's stable in solution or is it just arbitrary? Say you want to run 600 mg test per week, with 300 mg/ml that's 2cc per week, but would it be possible (in theory) to concentrate test at 600 or even 1200 mg/ml and cut down on the number of injections?

The only thing I can think of, assuming you could get that concentration to be stable, is that it would be absorbed too quickly because there'd be so much Test in a single cc, is that the case, or would the body still utilize it at the same rate and you'd just be injecting weekly or bi-weekly instead of 2x per week?
