Alin: Yeah I'm going to combine them in the syringe, not the vial. I mis-spoke.
Zorrin: I'm not going to shake it up before I pin it, I'm not trying to mix them. Just shoot them together.
Steve: Everything I've read for HCG says it's a deep IM just like everything except HGH and B12. Obviously combining two drugs that require different administrations would be impossible.
All the opinions on this board seem to be split down the middle on mixing oil and water based injectables. I'm not trying to mix it, and I understand different viscosities will give different resitances on the plunger... a lot of this is a no brainer.
I'm going to give it a shot (no pun intended), will post an update.
