So with a quick google search, it says that sustanon 250 has a molar mass of 288.42 which means that if I were to inject 100mg of sustanon I’m getting 100% of that right? So injecting 100mg of Sustanon converts to injecting 130mg of Cypionate? Or am I just completely confused
Testosterone has a molar mass of 288.43g/mol. Testosterone cypionate has a molar mass of 412.614g/mol
288.43/412.614= 0.699 meaning for every 100mg of test cyp you inject you get 69.9 mg of pure test, which means that 69.9 percent of it is test and the remaining is the ester however I could be wrong, I’m on school holidays therefore my math skillz are becoming rusty
Sustanon
30mg of test propionate
60mg test phenylpropionate
60mg test isocaporate
100mg test undec
Test props molar mass is 344.495g/mol
So 288.43/344.495 =.837 so 83.7 percent test props is test so 30*.837= 25.11
Test phenylprops molar mass is 420.5836g/mol so 288.43/420.5836=.685 (wow, I actually can’t believe the phenylpropionate ester weighs more than test cyp, there must be something wrong but anyway onwards)
60*.685= 41.1
Test isocaps molar mass is 386.5674g/mol
288.43/386.5674= .746
60*.746= 44.76
Test decs molar mass is 442.684g/mol
288.43/442.684= .651
100×.651 = 65.1
25.11+41.1+44.76+65.1/250×100= 70.428mg of pure test. The difference between injecting 100mg of each is very minute with regards to the amount of PURE testosterone your body receives, however sustanon, being a combination of short and a longer ester, will give the body a much higher peak and lower nadir whereas test cyp will peak and slowly level off.
To figure out exactly how much the difference is
.699*X=70.428= 100.75… so the difference in potency between the two regarding pure test (if we factor out the half lives of each ester) 100.75 mg of test cyp is the equivalent of 100mg of sustanon, not a significant difference at all.
