What is an ester
By: Hypertrophy
An ester is a synthetic modification of the hormone testosterone designed to have a slow release effect which can improve bioavailability. They achieve this by attaching a fatty acid to the 17β - hydroxyl group, which then renders them more fat soluble. This also allows for intramuscular injections.
Esterification
Before I go over esterification I want to briefly go over the testosterone molecule. The test molecule is made up of 19 carbon atoms, 28 hydrogen atoms and 2 oxygen atoms. These are configured into a steroid structure, which consists of four fused rings consisting of three 6 carbon rings (cyclohexane rings) and one 5 carbon ring (cyclopentane ring). The OH on the molecule stands for a hydroxyl group (an oxygen atom bonded to a hydrogen atom). Now this is where you’d put the fatty acid to form the ester like I said earlier (only talking about the OH group here because that's what's relevant).
Here I will provide a visual of the testosterone propionate molecule, you see how there are 3 carbons attached to the OH group? That's the fatty acid which gives the molecule its ester.
Now here is the molecule for Testosterone enanthate, see how there are 7 carbons on the OH group? That means a longer half life.
So yeah not really necessary to learn this but it's cool seeing the visual differences between esters and hopefully gave you a better understanding of this.
That's it bhais, rep it up
