I hope I can explain this decently. Please anyone else help me out here.
Spot injections are pretty controversial. Some say that Spot Inj with HGH or IGF works.
But with Test/Deca, Test/EQ, Test/Tren it is not. Or I would have the biggest ass on the planet.
Seriously all spot injections do is Saturate that muscle first, but it is still absorbed into the body.
This is were I am bad at explaining things. Im sure someone will pick this apart quickly....hahahahaha
If 2 people are the same size as one another, basically apples to apples, and BB1 injects 2xweek in his glutes while BB2 inj. 2x week in his Bi's. BB2 Bi's will look bigger cause of the oil in his arms. But it will be absorbed in days and go back to a normal size.
Hope this helps
