Since I posted the bit about what % of testoserone is in the various esters , I have been getting questions, so I want to explain it a little better. For our purposes here we will just do test cyp vs testE.
The weight or atomic weight of a molecule comes from the periodic chart. For example methane gas is ch4. This means 1 carbon atom with 4 hydrogen atoms attached. To calculate the molecuar weight we add up the sums of each element. Carbon is 12 and hydrogen is one, so the gram formula weight or atomic weight of methane is 12 +4=16. Without getting to far out I will just say this is actaully the weight of 1 mole of methane. You may have heard of avogadro's number, but we aint going there. So if we go to butane it looks like this c-c-c-c with 3 hydrogens on the two end carbons and 2 hydrogens on the two middle carbons. So the atomic weight is 12+12+12+12+ 10 hydrogens. So the atomic weight is 58.
Now to the testosterone molecule. The atomic weight is 288.42. The atomic weight of test cyp is 412.6. So the % testosterone is 288.43 divided by 412.6 x100=69.99.
For TestE the atomic weight is 400.59. So the % testosterone is 288.42 divided by 400.59 x100= 71.99.
So test cyp is about 70% test and testE is about 72% test.
Is this significant? Maybe...if you are using 100mg then with cyp you are getting 70mg test and with tesE you are getting 72mg. Not much difference, and the more you use the less significant it becomes.
Lets say we are using 500mg. Then 500 x.70=350mg test from testcyp, and 500x.72=360mg test from test E.
Now test prop is 83.7% test. If you were to shoot 150mg prop 3 times per week then you would get 376mg of test. Still kind of close!!!
So does 350 vs 360 vs 376 make a lot of difference? Up to you!!!
