Not even close.
If I'm making something simple that holds easily, say test e 250, then sure 2% BA, 20% BB, 100% GSO as the carrier is fine.
However that recipe won't hold higher concentrations, and if it does it will cause pain.
For my shorter ester compounds (Tren A,NPP,Test P,etc) I use a 50/50 mix of GSO and EO as the carrier along with BA and BB. This makes the gear very then and zero pain.
For my blends and higher concentration gear I use all the way up to 100% EO as a carrier and up to 15% Guaiacol when I need it such as when I make Test no ester (TNE). This results in gear so thin and clear I DRAW and inject through a 29g slin pin.
