i haven't really been on here much, but i thought it was time to plug in.
i agree with these guys. a couple things to consider are the dose concentration of your oils and what your history is with gear..
900 eq in one pin is a lot. the highest i've seen eq dosed is 400mg/ml, and that shit was thick. unless you're a well seasoned AAS user, i'm gonna bet that 2-3 cc is either pushing it for you or is your threshold. i'm a testosterone replacement therapy (TRT) guy and have been doing this for a couple years. highest i've gone in my glutes is 3 cc. depending on the oils, it either has me sore the next day or leaves a knot for a few days. not unbearable IMO, but who's to say the next man will respond the same way?
so, my question for you is: what are your stats (age, weight, and Bf), cycle history (how long have you been running gear and what compounds), and what is your current cycle?
almost sounds like you're trying to frontload the EQ with some prop in the mix? let's see the layout of what you're trying to do so we can dial you in, bro.
