My syntherol chest shots are going great. I am still using lower volume but that will be increased over the next few weeks. I have injected most days but had last night off. Gonna dose 2ml in 2 spots in each pec tonight though. They have had a big impact on my chest even after this short time. It's looking much bigger and fuller even on restricted calories.
I have been sensible when training it to avoid injury. Although I have still been pushing my training just not going super heavy with pressing. I did notice it felt very sensitive when performing behind the head lat pulldowns the other day. Plus when I do broomstick twists I can feel it loads then too. Basically anytime my arms are high up and behind my body my chest feels super tight.
I am purposely avoiding too many lower pec injections as they don't feel right but I still shoot there occassionally.
I will bump this back up for your question because I honestly don't know.
I have run Syntherol on bis and tris and probably past the point of ever doing traps like I had planned (especially considering I haven't juiced in almost 7yrs)...But from my experience with Syntherol I would think you would really need to have that pec lined out with where to inject to make sure to bring it up as evenly as possible?!
I have heard about people doing that but don't know anyone personally who has. The way I look at it what do you have to lose. It wouldn't make it look worse. Maybe just get 1 bottle and see if there is a difference using small doses.
Hopefully someone else can post who has done what you ask about.
