"What im thinking is, is there any specific aas specially suitable for recovering?"
Not an AAS. But a few weeks back read something about HGH/IGF-1 and regenerating muscle tissue at the cellular level and building new muscle fibers. Have a look at that.
IGF-1 Regenerating Nerves
Another exciting potential use of IGF-1 is in the repair of peripheral nerve tissue that has been damaged by injury or illness. If a nerve is torn in the arm or leg, it means that the connection to the muscle may be impaired, and as a result there is loss of movement and the muscle atrophies. While peripheral nerves can regenerate to some extent, severe tears of more than a few millimeters may result in permanent injury. Now IGF-1 has repaired and reconnected severed nerve endings of up to a distance of 6 millimeters, a feat previously unheard of.
Swedish scientist Hans-Arne Hansson of the Institute of Neurobiology at the University of Goteborg found that IGF-1 in combination with other growth factors could stimulate even more dramatic regeneration. "IGF-1 by itself and in combination with other growth factors is likely to be of importance in promoting healing and repair processes in clinical practice within a few years," he writes.
In studies of cells in culture and in animals, IGF-1 has been shown to have remarkable effects on the spinal cord motor neurons. It increased motor neuron activity in spinal cord cultures by 150 to 270 percent. And it significantly decreased programmed cell death in developing chick embryos. In animal studies, it enhanced the sprouting of axons of the spinal cord motor neurons. And it increased intramuscular nerve sprouting a whopping ten fold when it was given to normal adult rats. In fact, according to a group of researchers at Cephalon, Inc., in West Chester, Pennsylvania, IGF-1 may be the "long-sought endogenous motor neuron sprouting factor."
The implications of this work for helping people is nothing short of mind-boggling. If IGF-1 can regenerate spinal cord motor neurons, it may be useful in treating amyotrophic lateral sclerosis (ALS), a devastating disease in which the loss of spinal cord and cortical motor neurons results in complete paralysis and death. It may also be useful for peripheral neuropathies, such as Charcot-Marie-Tooth syndrome.
John Wittig, MD, of UCLA has been using IGF-1 to prevent AIDS wasting in HIV infected patients. IGF-1 may allow more aggressive chemotherapy of certain cancers, since drugs like vincristine and cisplatin can cause peripheral neuropathies at higher doses.
The Growth Factor Army
IGF-1 is only one of the body's many growth factors that are now being identified, isolated, and cloned using genetic engineering technology for use as drugs. As growth factor researcher Eric Dupont, Ph.D., says, "Growth hormone is the general and growth factors are the foot soldiers." Growth factors function like hormones, hooking onto the receptors of cells and sending a biochemical signal across the cell's interior. Whereas hormones usually send long distance messages, growth factors for the most part do local calls.
Hope that helps. Good luck!
