Sustanon 250 = 176mg as esters?

[melochai]

Wow, I am a newbie & didn't realize all of that but it does make sense.

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:
