newbie needs help!

been making tren for about ten years now. new to these forums. and first time making test p. don't use aluminum for mixing lye and heet ! so my questions are what is gso, ethyl oleate and can i make my test p without BB? and why would i need it? im 42, 205 lbs 5'9" 16%bf. been working out 20 years now. ten years with gear.

gso is grape seed oil and ethyl oleate is also another oil base i believe for gear, and no idea about making ur test p without bb sorry

Yes, I believe you can make P without BB but it will hurt a Whoooole lot more. I used to up my BB to BA ratio for this reason.
