My take on it is there is more to consider than just cost alone
The cost of QSC finished oils is very low. I’ve bought finished Tren A from them one time everything else has been raws (besides HGH and peptides of course). I don’t like the vials at all and I wanted to refilter so I filtered into much better vials which made the end cost of that kit go up.
With raws if you’re getting a decent amount you are limiting your legal exposure to a degree once you receive that one order. You’re not making a bunch of orders for vials. Everytime i need anything now I just brew up a batch of 50-100 ml. No ordering. Same thing with all my ancillaries. I just make up a 60 ml bottle of suspension in 10 mins every once in a while.
Also, purchasing the carrier oil, BB and BA covers you for many brews so it doesn’t factor into the cost as a one time purchase.
Other factors are choice of carrier oil, amount of solvents and concentration. You being able to brew Mast at 250 was a nice choice to be able to make to reduce oil volume. I’m running a large blast right now with NPP and Primo and Test and the oil volume is pretty high. Brewing my Test C at 300 mg/ml this time helped me to reduce my oil volume a good amount.
I also appreciate the confidence of knowing exactly how the brew was done start to finish. Sterile, accurate and control of solvents are all a plus in my book.
