some guys do get localized growth.
keep shooting in the same spot over and over you eventually get scar tissue and a sterile abcess.
Hey never said it was good growth.
the theory with the spot injections is that when you inject a substance into your muscle it builds a small pocket of oil. the oil presses apart muscle fibers that are very dense and packed together
by hitting the same area over and over the area that has been kept open by repeated substance injections will eventually fill in with new muscle .
It has been proven that you can grow very eazy but the problem is your fascia around the entire muscle and around each group of fibers inside the muscle are wrapping the muscles keeping them tight and preventing growth
this is exactly why guys that are " natural" after stopping steroid use will always be bigger then most naturals becuase they have stretched out the sacks with drug induced growth and the muscle itself is not as restricted .
people and animals with agenetic disorder that cuases the collogen wrapping around the muscle to be more elastic then normal people.
ths is what flex wheeler claimed to have that allowed him to look failry normal a few hours after a work out then pump up in a hour of weight training and look like a entirly different person.then later he claimd to have a hormonal imbalance cuasing eazy feakish growth that most guys could never achieve even with steroids
synthol is proof that site injections can cuase growth becuase a person can accomplish the same thing with daily injections of Equipoise - boldenone undecylenate - or even sterile grapseed oil.
Most do ,pros dont get golf ball sized bicep peaks without spot injections
be it temp swelling for a show but still they do get local swelling and growth
(for how long prob as long as they keep doing the site injection)
