Ok, here are the molecular weights for some common hormones and esters, in case anyone was wondering the specifics:
Test: 288.429
Nandrolone(deca): 274.4022
Trenbolone(fina): 270.3706
Boldenone(eq): 286.4132
Methenolone(primo): 302.4558
Acetate ester: 60.0524
Propionate ester: 74.0792
Phenylpropionate ester: 150.174
Enanthate ester: 130.1864
Cypionate ester: 132.1184
Decanoate ester: 172.2668
Undecanoate ester: 186.2936
No need to read below unless you feel like doing math, and have some reason to need to know what percentage is hormone.
Lets use test enth as an example... the base is 288.429, plus the ester is 130.1864.. for a total molecular weight of 418.6154. From the above, you know that enth weighs 130.1864, so divide that by 418.6154 and you get .31099. So you can conclude that test enth is about 69% test, and 31% ester... IE 100mg test E is 69mg test, 31mg enanthate.
Now, the above isnt the exact science, there are other factors at play, but this will give you a general idea. For instance, the REAL molecular weight of test enth is 412.6112.. which is lower than adding to two together... but this isnt chemistry class, so i wont get into molecular bonding and all of that.
Hope this was usefull to someone
