Testoviron is a blend of two different products, Testosterone Propionate (short ester) and Testosterone Enanthate (long ester).
This product is manufactured by Schering. Blended esters are the most expensive of all of the Testosterones available due to the fact that they are rare as well as in high demand. Testoviron can only be found in the Dominican Republic and Italy (135mg versions available in both countries).
Testosterone is responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean muscle mass, preventing Osteoporosis (loss of bone density) and possible protection against heart disease. Testosterone is also responsible for normal growth and development of male sex organs and maintenance of secondary sex characteristics. Secondary sex characteristics are specific traits that separate the two sexes, but are not directly part of the reproductive system, for example: chest and facial hair, a distinguished jaw line, broad shoulders and increased muscle mass. Testosterone binds to the Androgen Receptors (AR), which thus causes accelerated muscle gain, fat loss, and muscle repair and growth. These mechanisms are stimulated by activation of the Androgen Receptors (either directly or as DHT).
There are many possible side-effects associated with its use. This product also has a high level of aromatization into estrogen and coverts to DHT (dihydrotestosterone) as well. Also, supplementing Testosterone to your body will result in the shutting down of the body’s natural production of the hormone. The severity of side effects depend mostly on the levels and duration of circulating free testosterone, and its conversion to substrates. Testosterone’s anabolic/androgenic effects are dependant upon dosage, the higher the dose the higher the muscle building effect (and often, it’s side effects). Testosterone promotes aggressive and dominant behavior.
Testosterone is the best mass builder known to man and recommended as the base of any mass building cycle.
Testosterone’s anabolic/androgenic effects are dependant upon the dose administered; usually the higher the dose, the better the results (1). In a study done on Testosterone Enanthate in this case), a dose as high as 600 mg’s (per week) produced better results in subjects compared to those who received all of the lower doses. At the highest dose, 600 mg/week, the greatest results were achieved in comparison to any of the lower doses studied. The highest fat loss, most muscle growth, and increased size and strength were achieved at the higher dose (2). In the same study, HDL cholesterol was lowered and the subjects experienced acne. There was roughly a 15% gain in Lean Body Mass from 20 weeks of 600mgs/week of Testosterone therapy.
Overall, the most common report by subjects using testosterone was immense gains in strength (3). Alterations in size, shape, and appearance of the muscle were reported (4).
Due to stimulation of the Androgen Receptors (either directly or as DHT), accelerated muscle gain, fat loss, increased muscle repair and growth was experienced (5)(6). Testosterone binds to the A.R. on fat cells; therefore, adipose (fat) tissue can be broken down more readily while new fat formation is prevented (7). Since the body is building muscle at an accelerated rate, more ingested food is shuttled directly to the muscle tissue (this is known as nutrient portioning) and away from fat. This is another indirect effect of testosterone on fat loss. Testosterone also promotes glycogen synthesis, which is activated by insulin in response to high glucose levels (8). Glycogen provides fuel to the muscle; therefore endurance and strength increases were reported during severe muscle breakdown in intense training and workouts.
Testosterone also converts to both Estrogen (through Aromatization) and Dihydrotestosterone (through 5a-reduction). Most of the side effects people experience with testosterone use is actually from it’s conversion to these two substrates. Hair loss, water retention, acne, and other side effects are possible with use of this drug.
Also noteworthy is that testosterone administration causes the shutdown of natural testosterone production.
Testoviron is actually a very decent anabolic, and is very rarely counterfeited any longer. Basically, what we’re looking at is a nice pre-mixed blend of Testosterone with a long ester (Enanthate) and a short ester (Propionate). If I were personally to make my own test blend to use every other day, it would most likely be something very similar to Testoviron.
The short ester will give you a nice spike in testosterone levels, albeit one that decays very quickly, while the longer ester will allow a very slow decay in blood plasma levels.
One of the primary advantages to this version of testosterone is that it is very rarely faked because products like Sustanon (a 4 ester blend) fetch a higher price, and if you’re going to counterfeit an amp, it may as well be the one which will earn you the highest profit for your trouble. This is why we never see counterfeit “Sten” amps (a very low dosed preparation of testosterone) and this basically holds true for Testoviron as well.
If you can find it, and it’s not any more expensive then single ester testosterone, Testoviron is a very nice buy on the black market.
