Different Testosterone Basics

[longhorn71]

You have probably seen the many types of Testosterone in the AAS world and you are probably asking yourself, what’s the difference between Testosterone enanthate (Test E) and Testosterone propionate (Test P)? Or which one is stronger?

This is pretty simple to understand. Testosterone is plain old Testosterone, but if it’s injected in its purest form it’s broken down very quickly. A long time ago some pretty clever organic chemists came up with a way to make Testosterone break down much slower in the body, and this process is called ‘esterfication.’

When you read Testosterone enanthate, Testosterone propionate, or Testosterone cypionate it’s natural to get confused but all that fancy word after the word Testosterone means is which ester has been attached to the Testosterone molecule. The longer the ester, the longer the ½ life of the Testosterone molecule. To put it another way, the longer the ester the longer it takes the Testosterone to be broken down and used. Testosterone cannot bind to the Androgen receptor if its ester is still attached to it. So how does this work?

You inject some Testosterone into your glute, where a lot of it stays but some is released into the bloodstream, albeit slowly. As it is slowly released into the bloodstream enzymes come along and react to break off the protective ester, once this happens the Testosterone is free to do its magic. This process is very gradual and slow. Of course depending on the exact ester the blood concentration of Testosterone will rise and dip accordingly.

Since Testosterone propionate has a very short ester, it must be injected either everyday or at least every other day to maintain blood levels. Enanthate and cypionate are almost identical in their ester and have longer ½ lives and therefore most will only inject these twice per week or at the most every third day.

Also worth noting is dosage. The shorter the ester then the stronger that Testosterone’s concentration is per ml. Example, out of 100mg Testosterone propionate, 83mg is actual Testosterone while the other 17mg is the propionate ester. The value for Enanthate is 72mg and 70mg for cypionate.

So what about Sustanon 250 you ask? Sustanon 250 (Sust) is a mixture of 4 different Testosterone esters, namely : Testosterone propionate (30mg), Testosterone phenylpropionate (60mg), Testosterone isocaproate (60mg), and Testosterone decanoate (100mg). So if you add all those up you get a total of 250mg, which is how Sust 250 gets its name.

Sust 250 is a nice blend of fast acting Testosterone (meaning those that have shorter eters), and longer acting Testosterone (meaning those that have longer esters). Now a lot of people have had really nice results from Sust 250, so I am not here to bash it. I am, however, a little suspect of it and here’s why.

Most people dose Sust 250 twice a week or every third day at the most. Starting dosages is about 500mg a week or two shots of 1ml each spaced out. The two fast acting Testosterones in Sust are dosed in fairly low quantities, and to make it even more suspect the short acting ones are not being dosed every or every other day. In a typical Sust 250 dosing schedule you are only getting 60mg of Testosterone propionate in a week!!!! A lot of people use Testosterone propionate at a level of 400mg a week or more.

So in my opinion, those that have had good success on Sust 250 have done so at the benefit of the long acting esters in it rather than the short ones. It seems like it would be wiser to save some money and simply go with Enanthate or cypionate by themselves.

Good one, you know, i don't think I saw the Susatanon in the Profiles section. I might have to bring that one up to admin to throw in over there.

Longhorn, are you and Tigger sitting here writing all these things? or are these copied from another board or website?

Also, i thought it was "esterfication" not "estherization"....i could be wrong though.

[longhorn71]

Yeah, I wrote mine. I am not sure about tiggerizme. You're correct, sir...it's esterfication...I stand corrected and I am going to correct the post.
