I've been asked for a brief explanation on the Somedin (IGF1) 2 products - Let me make a quick reviw for u bro - The more popular and know is the IGF1-lr3, but the IGF1-DES is a very interesting product which may offer some unique benefits for some specific goals. The lr3 has an autocrine effect, meaning it is absorbed into the serum and from there interacts with its receptors on various target tissues, actually there are target tissues for IGF1 almost on any organ besides brain and eyes. Also very interesting is (as you may learn from the article I quoted in this GH section - http://www.ncbi.nlm.nih.gov/pubmed/10571453) IGF1 has a distinct and dramatic anti catabolic effect, which GH doesn't (even that GH does increase serum IGF1 levels). Along with the IGF1-lr3 we have the IGF1 -DES. This product has more of an paracrine effect, meaning it's absorbed in more of a local fashion and effects target tissues in the location of the injection, The DES is of course also absorbed into the circulation, but unlike the lr3 which has a half life of about 20 hours, it has a very short half life so most of the effect is local, this is an advanced way to cause some local growth in certain stubborn muscles.
