Noxious input to the spinal cord is known to produce central sensitization, which consists of allodynia , exaggeration of pain, and punctuate hyperalgesia , extreme sensitivity to pain. Two types of mechanical hyperalgesia can occur: 1) touch that is normally painless in the uninjured surroundings of a cut or tear can trigger painful sensations (touch-evoked hyperalgesia), and 2) a slightly painful pin prick stimulation is perceived as more painful around a focused area of inflammation (punctuate hyperalgesia). Touch-evoked hyperalgesia requires continuous firing of primary afferent nociceptors, and punctuate hyperalgesia does not require continuous firing which means it can persist for hours after a trauma and can be stronger than normally experienced. In addition, it was found that patients with neuropathic pain, histamine ionophoresis resulted in a sensation of burning pain rather than itch, which would be induced in normal healthy patients. This shows that there is spinal hypersensitivity to C-fiber input in chronic pain. 
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
So I would workout every SINGLE day and nothing, no improvement what so ever on my body. So I tried stacking with crazymass products. Right now I’m trying paravar and clentrimix. Its only been a month, I changed up my routine to start doing P90X and I have seen results already. My thighs have gotten thicker, arms are more defined and my back is looking amazing, did I also mention that my stomach is looking flatter. It definitely cuts some fat and forget the scale, just threw that out since I’m going off the body fat. Only problem is I always forget to take my pills so I probably could see better results if I stuck with the same time and pushed myself more at the gym. Overall its pretty good for it being a month into the first time stacking and we will see the results in a few more months. I’m taking pics too, Will post later. I will try winni once my bottles are running low and try those.
