Sidenafil, commonly known by the trade name viagra is an oral medication used for the treatment of erectile dysfunction (ED).
The function of Viagra is relatively simple – it relaxes the muscle and increases the blood flow to the penis. An erection is nothing more than blood flow to the penis. When blood flow is weak so is the erection. If we increase blood flow we increase the strength of the erection and the ability to maintain it.
The specifics of action involve the binding of nitric oxide to the guanylate cyclase receptors, which increases cGMP levels. This produces a smooth muscle relaxation, which in turn opens the pathway for increased blood flow. Viagra belongs to the class of drugs known as cGMP Specific Phosphodiesterase type 5 or PED5.
Important note: Viagra as well as other PED5 medications cannot cause or promote an erection without sexual stimulation. They do not have an effect on libido. The subject must be sexually aroused to obtain an erection. In the case of Viagra the problem for the subject is that the desire is there but the erection is not found. Viagra should reverse this issue if blood flow is the cause.

Sustanone 250 is a testosterone hormone. Although synthetic it is a perfect replica of the naturally produced primary male testosterone. What defines Sustanon 250 and differentiates it from other testosterone compounds are attached esters.
Testosterone Enanthate is a single large ester base testosterone compound. This is a pure synthetic testosterone hormone that has a carboxylic acid ester attached in Enanthate (enanthoic acid). The ester itself is attached to the hormone at the 17-beta hydroxyl group
Boldenone is a structurally altered form of testosterone. It is a very slight change in an added double bond at the carbon one and two position. This double bond greatly reduces the hormone’s androgenicity, as well as estrogenic nature.
