check out this answer i got from DR G from gear depot...i asked this same question to him on the "DR G thread" on this same page... he said-
===========================
A great question was asked by PitbullTank about site injections and I would like to discuss further what I have researched and learned over the last few years. Site injections happen with pretty much all AAS in some sort of fashion. In a scale of 1 to 10 it can be from 1 to 10 depending on the compound and whether it is esterified and if so how long of an ester is attached. Typically the shorter acting the compound the more "likelihood" that it will have site enhancing properties. And then there are certain compounds that just on their own have been known or shown to have site enhancing properties. Test suspension and winstrol are two that i have seen with great results. But during my research with Schering, there was no question that nandrolone as a whole even though not being "short" acting by any means had significant site enhancing properties. I do have to say that we never researched for this purpose in any human subjects. However, in many animal studies injecting nandrolone compounds particularly NPP, there was definite site growth and it was not inflammation but actually hypertrophy of the muscle fibers that was very significant.
Some of the other agents that are not AAS but also can have significant site growth are HGH (when injected deep IM), IGF DES and PEG MGF. I have several pro athletes as my patients that inject HGH intramusculalry and the results are amazing. Technically and assuming you have legitimate DES and MGF, they will work even better. DES is an amazing compound is several folds more anabolic that IGF-1. Because of its structure, it is able to bind to lactic acid degraded receptors which neither IGF-1 or LR3 can bind. Also because of its short half life it causes its action locally where injected before it becomes inactive. PEG MFG is also an amazing compound as it is usually produced by the muscle cells during exercise in response to damage so it can heal and has proliferation and hyperplasia capabilities. The biggest problem here is that as some of you guys know getting quality DES and MGF is almost impossible these days at reasonable prices. I am very skeptical of DES that is sold at these crazy prices by all the peptide companies. Having said that, assuming you have legitimate DES and PEG MGF both combined with an AAS such as NPP locally would be an amazing 1,2, and 3 knockout combination. DES should be used IM 15min prior to work out and PEG MGF immediately post work out.
I hope this answers your question and please continue to add questions and bump this thread so I can reply in a timely fashion. Thank you once again PM for allowing me to be here.
