Yea it is possible to have the "free" or "pure" testosterone in solution. The enanthate, propionate, cypionate are just hydrocarbon chains that form an ester bond with the testosterone backbone. The whole point is just to lengthen the hydrocarbon chain to make the compound more lipid soluble. When a particular enzyme comes along in the body, it chops (hydrolyzes) the ester bond to cut off the long chain. Then the testosterone is free, active, and more likely to dissolve in the blood stream. Different esters take longer to cleave than others, so you get the different half lives we all know about.
Anyway, all that being said, you can certainly make a solution with pure testosterone (no ester linkage). I've seen the powders sold. It would be fully active upon injection, and quick to make it's way into the bloodstream and muscles. (Even faster than acetate). It would require daily injects to have any steadiness in the blood levels. The same could be true of the tren.
But yea it's possible. However, I'd say there's no real benefit. Better to make even the short ester form than the free form in my opinion for steadier blood levels. Plus it's easier to store and more lipid soluble when prepping the solution. Just an opinion.
And you should definitely ask him how he "tested it out" to be around "350 mg/mL." Based on how it felt? Ask if he means the total of both test and tren with that number, or each seperately? If so, how much of each? Regardless, that's a really high concentration. I don't think it would even stay in solution at that concentration. Sounds like some bs to me. (stands for bullshiz or broscience. take your pick)
