It's marketing, on expensive substances it sells more a less expensive vials (even if the price is just half of the double concentration one) because of tricks the mind play.It always boggled my mind when they always brewed it at 50mg/ml.
Back in the day when Pure Oils released the first "real" trest on the market, it was 50mg/ml, but that was due to lack of raws/cost. Since then everyone followed suite.
It's the same when you go to a supermarket and you see things 9.99c instead of 10.
Because average ppl brain see 9 not 9.99.
If there was no pip difference for example it's a lot easier to sell 10 vials of primo 100 at 60 each then 5 vials of primo 200 at 120 each.
Same total cost but the impact when looking at the price is night and day.
Average person can't even do basic math xD
