Practical advices on the drug use. There are not so much data about the use by the athletes of IGF-1 long R3 around the world, so it is difficult to give any specific recommendations on the drug use yet. They just begin to gather data on the use of the given drug (we mean IGTROPIN). One can say with absolute certainty that the greatest effect has local administration of IGF-1 long R3, that is, its injection into the muscle the growth of which you want to initiate (3). We must say that local application of IGF-1 long R3 is even more effective than injections of synthol. In the circle of professional bodybuilders become very popular combination which includes in addition to somatotropin and IGF-1 long R3 testosterone, insulin and triiodothyronine. One of the first who used this combination in practice was Dorian Yates. We must say that for that time the above combination has benefited the quintuple "Mr. Olympia". Although in the case of IGTROPIN use, its usage in combination with the growth hormone, as we have found out, has little sense because the half-life of the drug is large enough. While administration of testosterone, insulin and triiodothyronine may be reasonable – all of them stimulate the secretion of insulin-like growth factor by the liver, and in combination with IGF-1 long R3 injected locally it provides a truly "bomb" effect. Testosterone, among other things, increases the number of cells-satellites, which are, as we have said, the material necessary for the formation of new muscle fibers. So we can not escape from its use. But we will repeat that at present the experience of the IGF-1 long R3 use is just beginning to accumulate, therefore we will not give any specific recommendations on the use of the drug, terms of use, dosages of IGTROPIN and "related" products in this article. Regarding the weight training, here a special emphasis must be made on the methods that lead to a marked muscle burning - combined sets, supersets and trisets, drop-sets, forced repetition. Periodic "pumping" gives good results also. Most recent studies have found that stretching exercises especially those that are performed after work with heavy weights cause significant increase of IGF-1 long R3 level in the body. It should also be said about negative effects of such antiestrogen as tamoxifen on the secretion of insulin-like growth factor. So, if possible avoid its use. Thanks God we have wide range of antiestrogenic drugs in our market. 

In any case, we may say for sure that there was a real breakthrough in sports pharmacology. A new drug appeared. And this drug can provide significant assistance to the athletes in the process of muscle mass grow. In this sense it is difficult to overestimate IGF1 long R3.
