I would use it subQ at night to help body rest/heal and build lbm faster in recovery. I think you could use it at higher dosages subQ, no reason not too except for $$. As for IM, people started using pegMGF when it first came out at dosages of 200-300mics x 2 per week and it was NOT effective. I believe to see effects using this protocol requires higher dosage of at least 1mg per week.
BI-LATERAL refers to the fact that you have 2 bicepts --> a left and a right, same with calves, tricepts, quads, etc. Therefore when doing IM spot injections, you should inject BOTH sides ---> injecting BOTH left bi AND right bi. Bi Lateral refers to BOTH sides.
