Steroids ... voice grew deeper, and she even had the beginnings of a mustache. These are all the usual symptoms of anabolic steroids.

Victims of starvation and severe injury profited from it's ability to build new tissue quickly. They also helped prevent muscle tissue from withering in patients who had just had surgery. ...

On the other hand, there is no PCP-like result when the test animals are given drugs which selectively bind to sigma and/or dopamine reuptake sites (Svennson, 1995). Second, "psychotomimetic effects similar to those induced by PCP can be induced by ketamine, a related arylcyclohexamine derivative" (Sevvenson, 1995). This is a ... previously unknown as to which receptor was more important in stimulating dopamine release, the PCP receptor or the sigma receptor (Halberstad, 1995). To find out, scientists gave test animals one of five PCP-receptor specific drugs; MK-801, PCP, (+)SKF, or ketamine (Restak, 1994). The degree of A10 excitation was then measured. With MK-801 being the most powerful PCP ligand, a 40% increase in A10 neuronal firing rate is detected ... DTG having no measurable effect (Halberstad, 1995). Moreover, A10 activation by PCP is not attenuated by haloperidol; which has the highest known sigma receptor affinity (Halberstad, 1995). In other words, "The potency of PCP-like drugs to alter A10 activity was found to correlate positively with their affinity for the PCP receptor and consequently with their potency as NMDA agonists". (Halberstad, 1995) The obvious conclusion to draw from the above ...
