The 4 main esters of testosterone

Hello bhai’s :peepoWave:

This will be an intro to the 4 most common esters of testosterone. I built this intro as to help educate dummies new to pharmacology while also teaching myself. :bigbrain:



Hopefully at the end of this the dummies reading this will be slightly less dumb and less irritable to the higher iq minded in this forum!





Simply put first what is an ester? :think3D:

Esters are chemical compounds formed into prodrugs to help with the drugs bioavailability and body’s absorption of the compound. Can be either long acting esters that take longer periods of time for the body to absorb into the system and exit longer or short acting esters that enter quickly but also exit the body quickly.



What are they? What are the differences? And which one is best for you?

💪




Testosterone Enanthate

Let’s start of with the most popular form of exogenous testosterone often referred to as the “gold standard” of testosterone esters.

Enanthate is considered to be the closest identical ester to endogenous testosterone due how bio identical it is. a half life of 4-5 days it’s a medium acting ester. The amount of time expected for it to be fully absorbed with maximum results to be 3-6 weeks of consistent injections 1-2x a week.
(Most popular outside of the US)




Testosterone cypionate

Cypionate another great choice as seen bio identical to endogenous testosterone contains a half life of 7-8 days. It is quite identical to Enanthate with the biggest difference being how frequently injections must occur with a slightly longer half life. The amount of time expected for it to be fully absorbed with maximum results to be 3-6 weeks of consistent injections 1-2x a week.
(Popular choice in the US)




Testosterone propionate

A much shorter half life compared to the other two at a measily 24 hour half life, requiring pinning every day just to keep the dosage in one’s body. However it is much faster acting and will enter one’s system immediately. Everything about this ester is quicker, the spikes, how fast it aromatizes, and how fast it exits one system (this isn’t always a bad thing!) However due to this you will retain much less water compared to the other 2. Maximum effectiveness can be expected 2-4 weeks in, pinning ED or EOD.





Testosterone undecanoate

For sure the longest lasting ester of the 4, with a half life of 3-5 weeks. The long lasting half life allows to very few injections, however one thing I will note about this isn’t always best as the serum drop off when upcoming to next injection can cause imbalance. Despite this due to the long acting it will be MOSTLY stable. However if taken orally the half life is much shorter at a measily 2 hours. The oral is quite less potent as well.

interesting to note there’s both an intramusculature injection and an oral 🧐

Hopefully this graph helps w understanding
When to expect peaks and hormone levels of the esters based on next administration!
(Note everybody will react slightly different to when certain esters peak)

Keep in mind at the end of the day testosterone is testosterone. None of these have special super powers or give extra levels of xp from one another. It mainly comes down to half lives and injections. It’s all going to be preference and goals.



Hope you enjoyed my friends, this was pretty fun to make lmk if y’all would like more and give me any tips to hopefully improve my threads :pepeD:

Oh yes I briefly touched on that with propionate carrying less water, but agreed
