Sustanon 250 = 176mg as esters?

I need a little help clearing this up . l have organon sust. 250 , now on the box it says 30mg Test prop , 60 mg test phen , 60 mg test iso. and 100mg decan.
But on the bottle it says 176mg as esters??? I dont understand.
 
to put it short.. the ester if what carries the testosterone. its like the delivery method... that takes of space as well.. so im assuming you are recieving 176mg of actual test where as the other 74mg are lost to the ester weight.. seems a little high but could be right..
THATS WHY U USE PROP... hehe

Youve got to be kidding me.
 
bro im sure a lot of people on the boards dont realize that esters take up mg's...... its better than an "how do i get ripped for spring break" or "a d-bol only " thread... its a message board.. people ask questions.. some of them legit...
 
Yes, esters take up part of the weight, you can figure out the ratio of test/ester to figure out how much actual test you get per MG.

Testosterone Base 288.429

Esterweights:
Propionate (Propionic acid = 3 carbons) 74.0792
Phenylpropionate (Propionic acid phenyl ester = 9 carbons) 150.1768
Enantate (Enanthoic acid = 7 carbons) 130.1864
Cypionate (Cypionic acid = 8 carbons) 132.1184
Decanoate (Decanoic acid = 10 carbons) 172.2668
Undecanoate (Undecanoic acid = 11 carbons) 186.2936
Undecylenate (Undecylic acid = 11 carbons) 186.2936
 
Yo hangclean nice answer dumb fuck. Its ok to be a smartass if you give a answer but if you dont have a answer then shut the fuck up.
 
So let me see if I got this right.An ester is test,s vehicle /binding agent into our body.And my 250 mg of sust contains 176mg of ester and the remaining 74 mg contains 250 mg of Test. Is that right.
 
So when im working out how much to take ie ive been takeing 2 x 1ml sust 250 per week, does that mean im not takeing enough? Im takeing 2 x 176mg a week? See what im getting at.

Depends on what you are trying to do. Everyone reacts differently and has different goals. I think 500mg sust a week is fine but that's just me. I know I would get bigger and stronger from it.

I think a good dosage to aim for is taking just enough to get the results you are looking for without taking too much.

What im trying to figure out is if im takeing 500mg a week or infact takeing 348 mg per week of test? Box says its got 250mg of tests in it bottle says 176mg ??Im still confused or is that im just stupid?

Like juicedathletics said you have 176mg of Test and the rest is taken up by the esters. I haven't looked each ester up and done the math but it sounds about right.

So if you are injecting twice a week you are injecting 348mg of test.
 
no, not stupid bro, it can be a little confusing, when people talk about using a certain amount of test, they are talking about the amounts that the test and ester weight, as you said you are taking 500mg of sus a week, that is just 500 of sus a week, everybody that knows any better knows that it is not actually 500mg of testerone, but thats just how we do it, 500mg of sus is a good beginner cycle yeah you might only be getting 352 of test, but you are doing 500mg of sus.

that is why they also say prop is the strongest, because you get more test out of it then the rest, but it really doesnt matter that much, just take it as its labeled, we all do
 
Maybe this helps. Test is test, all the esters do is deliver it or break it down at different rates. This is why Sustanon has multiple esters to try to arrive at the smoothest yield in the body. Example being it is designed to be injected every 3 weeks and provide the most stable blood levels between injections. Single ester preps are not as stable i.e. the shorter the ester would spike earlier in the 3 weeks and then taper to nothing while a very long ester would not provide much initially and build in later. So that's the job of esters and why sustanon is blended that way. It's about long periods between injection and achieving the most stable blood levels between those points. Test is test, the attached ester just controls the timing.

Now knowing that, all these different esters have a weight and it's like a spectrum. The lighter esters are the fastest acting and the fastest to clear - so think prop here and even suspension which has no ester. As the ester gets longer into a cyp or enanthate or decanoate these esters weigh more and more while they become slower and slower acting.

So now you know that each ester has weight, the longer the ester the heavier it is, the longer the ester the longer the time, that test is test regardless of the ester attached, and that test has a constant weight. So when you have 100mg of pure suspension, you have more test molecules than in 100mg of proprionate (because the attached prop ester increases the total weight so less test per total weight to make room for the ester). This continues right down the scale as the esters get longer you get fewer total testosterone molecules in the same total mg weight. This is one of the reasons why people say that suspension or short esters are stronger, you just plain old have more molecules per mg.

Your Sustanon breaks out how much of the weight is actual testosterone. So if you have 176mg of test in there, it's the same as 176mg of suspension (which has no ester). So in reality you are not getting 250mg of test a week, you are getting 176mg every injection. They don't gross up the total mg to equalize test content, they simply weigh the whole substance ester and all which, when you hold mg constant between different compounds, means that the amount of test will varry due to the weight of whatever ester is attached.

That is a very good post, good info bro

Great post bro! K your way. ( post of the day if not the week)
 
Guys big thank-you to all for takeing the time to explain that to me.Ive asked several local gym "no it all legends", and none of them could explain it.Amazing how little some people know about what they have been doing to there body's for years. :beer:
 
I found this old thread in a search. I was hoping somebody could explain this to me so I would understand how to figure out just how much test I'm actually getting. Is there a formula or what?

Pharmaceutical Name: Testosterone (as Cypionate)
Chemical structure: 4-androstene-3-one,17beta-ol
Molecular weight of base: 288.429
Molecular weight of ester: 132.1184 (cypionic acid, 8 carbons)
So % of test per Molecule = 68.584 %
100 mg of test Cyp = 68.584 mg is test

Pharmaceutical Name: Testosterone (as Enanthate)
Chemical structure: 4-androstene-3-one,17beta-ol
Molecular weight of base: 288.429
Molecular weight of ester: 130.1864 (enanthoic acid, 7 carbons)
So % of test per Molecule = 68.901 %
100 mg of test E = 68.901 mg is test

Pharmaceutical Name: Testosterone (as Propionate)
Chemical structure: 4-androstene-3-one,17beta-ol
Molecular weight of base: 288.429
Molecular weight of ester: 74.0792 (propionic acid, 3 carbons)
So % of test per Molecule = 79.566%
100 mg of test Prop = 79.566 mg is test

Pharmaceutical Name: Testosterone (as H2O suspension)
Chemical structure: 4-androstene-3-one,17beta-ol
Molecular weight of base: 288.429
So % of test per Molecule = 100 %
100 mg of test Suspension = 100 mg is test

Pharmaceutical Name: Testosterone (as 30 mg propionate, 60 mg isocaproate, 60 mg as phenylpropionate, 100 mg decanoate)
Chemical structure: 4-androstene-3-one,17beta-ol
Molecular weight of base: 288.429

Molecular weight of ester: 74.0792 (propionic acid, 3 carbons)
% of test Per molecule calculated above = 79.566 %
30 mg of test prop. = 23.87 mg is test

Molecular weight of ester: 116.1596 (isocaproic acid, 6 carbons)
% of test per molecule = 71.29%
60 mg of test isocaproate = 42.774 mg of test

Molecular weight of ester: 150.1768 (Propionic acid phenyl ester, 9 carbons)
% of test Per molecule = 65.760%
60 mg of test phenylpropionate = 39.456 mg is test

Molecular weight of ester: 172.2668 (decanoate)
% of test per molecule = 62.607 %
100 mg of test decanoate = 62.607 mg is test

So the summary is that 250 mg of sustanon contains = 23.87 + 42.774 + 39.456 + 62.607 = 168.707 mg of test

Thanks for the info there bro. I really do appreciate the effort, but what I am asking is ...How do you arrive at "100 mg of test E = 68.901 mg is test" ? Once you know the molecular base, the ester weight, and the number of carbonshow do you put it all together to get your answer? what + what / by what = what, you know?

For Testosterone Enanthate:

Molecular weight of one molecule of Test E = Molecular weight of test base + Molecular weight of Enanthate Ester

Now we know:
Molecular weight of Test base in one Molecule = 288.429
Molecular Weight of Enanthate Ester in one Molecule= 130.1864

So:
Molecular Weight of One Test E Molecule = 288.429 + 130.1864 = 418.6154
% of test Per Molecule of Test E= (Molecular Weight of test base)/(Total Molecular Weight of One Test E Molecule) * 100

So % of test Per Molecule of Test E = 288.429/418.6154 * 100 = 68.901 %
So amount of test Per 100 Mg = (68.901%) * 100 = 68.901 mg

I found the Molecular weights from this site; Just Click on the different types of tests in the drug profiles section and at the beginning of the profile you'll find the molecular weights:
