In response to site-injection questions:
I have read that you can inject into the biceps, triceps peak, top of triceps horse shoe, lateral delts, rear delts, glutes, thighs, and on some occassions, I have even heard of injecting in the lats and calves.
According to Chemical Muscle Enhancement, “any muscle could have been untilized for targeted site injection protocols.” The Author also notes that smaller muscles respond best to this technique, so he recommends delts, bi’s, and tri’s.
Also, never train a muscle that received an injection that day or the day before. IE, if you are going to train bi’s, wait until after your workout to inject the bi’s.
“It is important to do site-injections after the workout so as not to disturb the newly expanded muscle fiber area.” You will often be sore, but much, much larger.
According to the same author, “once had seen biceps that had been site injected a few hours before an arm workout, the bruising that developed looked like snake bites.”
The author recommends the following site injection protocol (remember to inject after the workout):
Day 1 Train legs, inject Tricep belly
Day 2 Train Chest, inject Triceps horse shoe
Day 3 Train Back, inject Biceps Peak
Day 4 Rest, Inject Lateral delts
Day 5 Train Arms, Inject Biceps Peak
Day 6 Train Shoulders/Traps, Inject Lateral Delt
Day 7 Rest, Inject Biceps Peak
Notice that he only injects in the bi’s, tri’s, and delts. Again, this is because he feels that smaller muscle groups get better results during site injections than larger muscle groups. But you can easily modify this protocol to meet your training schedule and if you want to rotate to the glutes and thighs.
Just remember to always aspirate.
