Context, despite how it might read.... I am not arguing with anything you said. I find this topic interesting specifically because of the difference in molar weight between NPP vs deca not actually being that much different. So I hope you don't mind me jumping in and being a little nerdy.
I've seen people get confused in the past thinking they are going to get a significant amount more actual hormone (different from active hormone released) between NPP and Deca. Typically it's true that shorter esters have a good amount more than longer esters, but in the case of nandrolone it's not that much actual not there's not a significant amount more of actual hormone between the two esters. It's only ~5% difference.
The main difference is the amount released over a period of time. However even this can be misleading. Let's say you take 100mg of NPP and 100mg of deca. The deca will take longer to reach it's peak value compared to NPP, but over time it will be pretty close to the same. The duration of each esters length does effect peak and trough values as well, but when averaging it out over the duration between injections they still come out to be about the same.
Here's the break down of amount of actual hormone in both esters, by using their molecular mass to calculate it.
Nand. (no water)molecular weight = 274.4
Nand. Decanoate molecular weight= 428.6
Nand. Phenylprop molecular weight= 406.6
Active hormone in 100mg deca: 100 *(274.4/428.8) = ~64mg
Active hormone in 100mg in phenylprop: 100 * (274.4/406.6) = ~67.4mg
The difference here is 5%, but the peaks are 15% when plotted out. I will admit that I'm too lazy to calculate the average amount of hormone released between injection frequency, but I promise it does roughly average out to the 5% difference between the two esters seen in the calculation.
This goes back to the point by
@rawdeal . The esters not only play a role in how quickly it's released, but it also factors in to the peaks and troughs due to the time span at which they are released.
I intentionally did my best to use injection frequency to get the peaks and troughs to be as similar as possible. Again, this is not exact... It's a just a calculated plot. However 5% difference in molar mass vs 15% plotted... Either way I'd think they'd both feel about the same when trying to use an injection frequency that would make the peaks and troughs similar.
