it cost about 20$ a gram for primo
There is other factors at play here. 100 gram powder may go for 2000 dollars but we are talking stomped on powder not 100% pure by any means, mass specs have shown the average quality of powders range from 45% to 80% and if testosterone is close to 80% on the good reputable raws then I suspect primo would be on the lower end.
Which means you would have to nearly double the powder to compensate and make a vial that truly has 1 gram in it, which means the price just went to 40 dollars, plus getting the vials and stoppers and equipment, put another few dollars in there and not including time
