An ester is compound that is added to testosterone to prolong its half life and viability in the body. Pure testosterone, if injected, has a very short half-life, lasting in the body for only a few hours. . Examples of testosterone esters include testosterone e nanthate, cypionate, acetate, propionate, phenylpropionate, isocaproate, caproate .
Testosterone Isocaproate (60mg) - Half-life = ~9 days, Testosterone Decanoate (100mg) - Half-life = ~15 days When determining injection frequency for an optimal TRT protocol, it's important to consider the shortest acting ester which, in this case, is the Propionate ester.

The esterified forms of testosterone possess a half-life ranging from around less than 1 day for testosterone acetate, 1 day for propionate, 2. 5 days for phenylpropionate, and up to 3. 1 days for testosterone isocaproate [ 11 ].
(1) The propionate ester is the shortest of all testosterone forms with a half-life of approximately 48 (2)The phenylpropionate ester has a half-life of 56 (3) The isocaproate ester has a half-life of 72. Sustanon 250 Cycle: The Ultimate Guide - Inside Bodybuilding. 60mg testosterone phenylpropionate; 30mg of testosterone What Results Can I Expect?
Testosterone Isocaproate 60mg. This ester is a mid-range release ester, and it's used to bridge the gap between the release of propionate and the decanoate ester. Since it has a 9 day half-life, I never understood why it was used instead of cypionate or enanthate, which have a similar half-life. I suspect this has to do with price.
Most begin to occur between 3 to 6 weeks after initiation, but some can take up to 1 year ( 6 ). Time-course differences are likely attributed to varying testosterone preparation pharmacokinetics (PKs). Common adverse effects associated with TRT are generally preparation-specific as well.
The different testosterone esters provide for different elimination half-lives in the body. Esterification of testosterone provides for a sustained but non-linear release of testosterone hormone from the injection depot into the circulation. Sustanon 100 is administered once every 2 weeks and Sustanon 250 is administered once every 3 to 4 weeks.
Half lives of testosterone esters are as follows: Sustanon/Omnadren 15 days Cypionate 12 days Enanthate 10. 5 days Propionate 3. 5 days Suspension 1 day or less Phenylpropionate 4. 5 days Isocaproate 9 days
Objectives: Identify the medically approved indications and contraindications for exogenous androgen replacement therapy. Summarize the adverse events and current research on contraindications with androgen replacement therapy. Review the dosing parameters for androgen replacement therapy.
The following shows how much testosterone is in 100mg and the figure in parenthesis is the ester chain molecular weight (MW) in case you which to apply this to nandralone, trenbolone e. t. c. All you need is the MW of that steroid. Test. Prop 84mg (56. 1) Test. Isocaproate 75mg (98. 2) Test. Enanthate 72mg (112. 2) Test.
Testosterone Isocaproate. Testosterone Isocaproate is the next step towards the longest of the esters contained in sustanon 250 - testosterone decanoate. This ester is also known as isocaproic acid, isohexanoate, and 4-methylvaleric acid. In comparison with the phenylpropionate ester, testosterone isocaproate has a longer half-life - 7-9 days.
The Testosterone IsoCaproate Profile will revolve around Sustanon-250 in part. You will find the Testosterone IsoCaproate Profile to provide solid dosing information. . As told earlier that it has got a more active life which means it will stay in the body for a longer period of time and therefore to get it in the form of an injection once or .
Testosterone caproate (TCa), also known as testosterone hexanoate, is an androgen and anabolic steroid and a testosterone ester that is no longer marketed. [1] [2] [3] It was formerly available as a component of Omnadren 250 , along with testosterone isocaproate , testosterone phenylpropionate , and testosterone propionate , but this .
Testosterone isocaproate ( BAN; TiCa ), sold under the brand names Sustanon 100, Sustanon 250, and Omnadren 250, is an androgen and anabolic steroid medication and a testosterone ester which has been used as a component of mixed testosterone ester preparations.

[2] [27] [28] The elimination half-life of oral testosterone is rapid at about 5 to 7 hours. [28] [30] As a result, it requires administration several times per day in divided doses. [28] Due to its limitations, such as the high doses required and necessity of multiple daily doses, oral testosterone is not used clinically in its unmodified form.
Testosterone isocaproate is one of the ingredients of the approved fixed-mixture drug Sustanonยฎ, which contains four esterized testosterone compounds ( testosterone phenylpropionate, testosterone propionate, testosterone decanoate) and is designed to provide sustained release of drug in to the bloodstream and more stable serum testosterone levels.
Testosterone isocaproate (Item No. 22547) is an analytical reference standard categorized as an anabolic androgenic steroid that can be detected in blood. 1,2 It is an ester of the naturally occurring androgen, testosterone (Item Nos. 15645 | ISO60154 | ISO60154) with a longer half-life. 3 Formulations containing testosterone isocaproate have been tested for use in hypogonadism and delayed .
Pharmacology Pharmacodynamics Testosterone propionate is a prodrug of testosterone and is an androgen and anabolic-androgenic steroid (AAS). That is, it is an agonist of the androgen receptor (AR). Pharmacokinetics Testosterone propionate is administered in oil via intramuscular injection.
Unmodified testosterone has a half-life of 10 minutes; to overcome this limitation, testosterone is esterified and then dissolved in oil to allow for sustained release into the circulation after injection. These oily solutions contain a testosterone ester dissolved in vegetable oil (usually sesame seed, tea seed, castor seed, or cottonseed oil .
The testosterone ester with the shortest half life is Testosterone Propionate with an approximate half life of 4. 5 days so it requires frequent injections. Most bodybuilders will inject this form of testosterone every two days, but some will even inject a smaller dose daily to maintain a high blood level.
