Testosterone propionate for growth of muscle mass and strength

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. 

Chemical Name: 4-Androsten-17beta-ol-3-one propionate

CAS NO.: 57-85-2

Einecs No: 200-351-1

Molecular Formula: C22H32O3

Molecular weight: 344.49

Standard: USP28/BP2003

General Description: Odorless white or yellowish-white crystals or a white or creamy-white crystalline powder.

Usage: Testosterone propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate,and requires a much more frequent dosing schedule,in order to maintain stable blood levels. Can be used as pharmaceutical material. Its main function is to Promote metabolism. Anabolic effects include growth of muscle mass and strength,increased bone density and strength,and stimulation of linear growth and bone maturation. 

Keywords: testosterone ester;Anabolic; testosterone compound;Androgen Receptors(AR) 

Description:

Testosterone propionate is a commonly manufactured,oil-based injectable testosterone compound. The added propionate ester will slow the rate in which the steroid is released from the injection site,but only for a few days. 

Testosterone propionate is therefore comparatively much faster acting than other testosterone esters such as cypionate or enanthate,and requires a much more frequent dosing schedule. While cypionate and enanthate are injected on a weekly basis,propionate is generally administered(at least)every third day. Figure one illustrates a typical release pattern after injection. As you can see,

levels peak and begin declining quickly with this ester of testosterone. To make this drug even more uncomfortable to use,the propionate ester can be very irritating to the site of injection. In fact,many sensitive individuals choose to stay away from this steroid completely,

their body reacting with a pronounced soreness and low-grade fever that may last for a few days. 

Even the mild soreness that is experienced by most users can be quite uncomfortable, especially when taking multiple pharmacokinetics of Testosterone propionate injections each week. The "standard" esters like in ection enanthate and cypionate,which are clearly easier to use,are therefore much more popular among athletes.

 

Applications:

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 indirectly as DHT).
