What is the difference between test propionate and enanthate

Fortunately, it was a straight swap due to the two chemicals being so similiar. A noticeable difference between Testosterone Cypiontae and Enanthate is the carrier oil. Testosterone Enanthate is dissolved in sesame oil which is very viscous. One downside of having such a high viscosity is that preparation of the injection with Enanthate can be quite time-consuming, which does not lend well to long-term patient compliance and concordance. I am becoming more and more of a proponent of subcutaneous testosterone injections.

The subcutaneous route allows for slower absorption compared to the intramuscular route, which in turn leads to more stable levels, decreased aromatisation of testosterone to oestrogen and less possible negative side effects. The high viscosity of the sesame oil in Testosterone Enanthate means that the medication can cause lumps within the skin and subsequent irritation, which some of my patients report as being quite painful.

Testosterone Cypionate uses olive oil as its carrier. Another consideration was that Testosterone Enanthate contains the preservative Chlorobutinol, which is a known irritant at high concentrations. It is typically only used at up to a concentration of 0. There is nothing wrong with Testosterone Enanthate, as already mentioned, the two esters are practically identical from a pharmacokinetic persepective.

The remainder of the biochemical analysis, hexosamine and hydroxyproline content, did not show a statistical difference in groups A, B, and C at 2, 4, and 6 weeks.

The biomechanical studies and histology also failed to show statistical differences between the three groups at 2, 4, and 6 weeks. The conclusion of this study is that an agent with a low androgenic activity does not increase calcium callus concentrations early in the course of fracture healing compared to an agent with higher androgenic activity.

Pure testosterone, if injected, has a very short half-life, lasting in the body for only a few hours. Aquaviron is a testosterone suspension unesterified testosterone suspended in a water base and must be injected daily in order to maintain a steady concentration and elevated level of testosterone in the body.

Aquaviron has the consistency of water and can be injected into the body via a small guage or gauge needle. Daily injection to testosterone would not only be uncomfortable but tedious to perform.

Therefore, esters are added to testosterone to prolong the half-life and slow the release of testosterone from the injection site allowing some injections to last up to 10 weeks.

There are a variety of testosterone esters and all have different half-lives. Examples of testosterone esters include testosterone enanthate, cypionate, acetate, propionate, phenylpropionate, isocaproate, caproate, decanoate, and undecanoate. Sustanan is blend of 4 testosterone esters. Sustanon is prescribed outside the United States and combines both fast acting and slow acting testosterone esters long and short half-lives.

Testosterone undecanoate will slowly release testosterone for up to 10 weeks. Testosterone Enanthate and Testosterone Cypionate are the most prescribed forms of testosterone in the United States today.

Most patients will inject Testosterone Cypionate or Testosterone Enanthate once a week or every two weeks.
