Hey guys

Is there is a possibility to use ethyl oleate 70% technical grade instead of 98% pharma version.

It`s a really expensive price. Costs of ethyl oleate 98% if I mix 1/3 ethyl and 2/3 oil will be around 35 USD for 10ml so this price is unacceptable.

Also ethyl oleate gives a painless injection or only let to make prop in higher concentration?
