Predefinito Testosterone-CHP - 27-06-2007, 04:14 AM

Testosterone-CHP




(various esters)

Basically, what we have here is a French Testosterone preparation. This means it comes in all sorts of weird dosing schemes, which are actually not too weird once you understand why they exist. See, this stuff comes in 296mgs, 148mgs, and 37mgs ampules, of one milliliter each. Why the weird dosing? Well, actually, it´s much less weird than you think. . See those amps provide a very sensible 200mgs, 100mgs, and 25mgs respectively with this particular ester, combined with testosterone, at those available doses. As we all know, esters delay the release of a hormone, and Test-CHP has 9 carbons, which hints that it is a long acting ester comparable cypionate, (8 carbons) or decanoate, (10 carbons) with an active life of about 13.5 days. Obviously, this is a very long acting version of testosterone, and anecdotally, the longer esters, tend to produce more water retention. This stuff would be good for bulking, therefore, and not really for cutting.
Testosterone, even with this absurdly long ester, is the hormone responsible for the different physical and mental (*sexual) characteristics males tend to have in abundance (and females less so). It promotes sex drive, fat loss, helps with gaining and maintaining lean muscle mass and bone density and may even protect against heart disease.(1) All other anabolic steroids are actually the testosterone molecule that has been altered in one way or another to change the properties of the hormone. But lets get back to testosterone. Test-CHP (or any form of testosterone) will bind to the A.R on fat cells resulting in fat break-down and also prevents new fat formation.(15) Testosterone CHP will also promote nitrogen retention in the muscle(2), which is good, as the more nitrogen the muscles holds the more protein the muscle stores, and the bigger the muscle gets. Testosterone has the ability to increase red blood cell production(9), and a higher RBC count may improve endurance via providing more highly oxygenated blood to working muscles. More RBCs can also improve your recovery from strenuous physical activity, and has a "volumizing" effect on your muscles. Testosterones´ anabolic/androgenic effects are dose dependant, the higher the dose the higher the muscle building effect(10), regardless of ester. Testosterone can also increase the levels of another hormone (*one of the super family of anabolic hormones), IGF-1, in muscle tissue(3). Testosterone also has the profound ability to increase the activity of satellite cells(4), which play a very active role in repairing damaged muscle. Testosterone binds to the androgen receptor tightly to promote A.R dependant mechanisms for muscle gain and fat loss,(5) and it also significantly increases the concentrations of the A. R in cells critical for muscle repair and growth and A.R in muscle.(4)(6). Testosterone induces changes in both shape and size of muscle cells, and also can change the appearance and the number of your muscle fibers (7). Testosterone-CHP administration will also protect your hard earned muscle from the catabolic (muscle wasting) glucocorticoid hormones(8). Testosterone greatly improves muscle contraction by increasing the number of motor neutrons in muscle(4) and also improves neuromuscular transmission(12). This is of special interest to strength athletes and sprinters. Test-CHP will also promotes glycogen synthesis(13) providing more fuel for intense workouts thus having a positive effect on endurance and strength. Finally, Testosterone-CHP will promote aggressive and dominant behavior(14), even though it is a still basically a French version of testosterone.
Testosterone-CHP use does have some unwanted side effects... it will convert to the hormone estrogen (via aromatization) by the now-infamous aromatize enzyme. This can lead to breast tissue growth in men (gynecomastia), increased fat gain and reduced fat breakdown, possible loss of sex drive, almost certain testicular shrinkage and finally water retention. Water retention with this product (because of it´s ester) will probably be very pronounced, and can increase blood pressure weakening blood vessels over a period of time.. Testosterone can also interact with the 5 alpha-reductase enzyme, which converts the testosterone to Dihydro-testosterone (DHT), a more androgenic form of the parent hormone. This new compound has a high binding affinity to the tissues of the scalp resulting in hair loss in loss in users who suffer from male pattern baldness. DHT can affect the prostate as well, making it swell. This swelling can cause the gland to press against the bladder causing urinary problems especially urinary difficulty.
Although Steroid.com has nearly 40K members, I haven´t found any who have used this particular version of Test, possibly because it was discontinued in 1991. If it were still on the market, or a UG began producing it, then it would be a good buy for those who are squeamish about needles, since once a week injections would be more than sufficient. Until then, though, it´s of note purely as an academic object.
