I think so many people place so much importance on prop in a blend out of ignorance. If it was easier to examine these cycles side by side, you all wouldn't find prop to be the dominant ester in a blend.
In sus 250, prop makes up 8% of the blend with the esters attached. It makes up 14% when only measuring the hormone without each respective ester. That is relatively small. Why would the smallest portion of composition be the most important? All measurements below are calculated by removing the ester as that is the realistic way to learn. If I did this with the ester attached, the results would be overwhelmingly against prop.
3E.5D
When comparing sus and E injected 125 every 3.5 days at week 10 there is a very small difference in how much is released into the blood stream.
Over the course of 7 days E releases between 23-28 mgs per day with a 7 day half life. The difference is 5 mgs from peak to trough.
Over the course of 7 days sus releases between 21-29 mgs per day with half lives of 2-prop, 4-phenyl, 6-iso, and 14- deca. The difference is 8 mgs from peak to trough.
The prop in the sus makes up 2-5 mgs of that 21-29. That is 9%-17%. That is also pretty small and shows the bulk of your hormone comes from the other esters (obviously).
Once per week
E releases between 19-32 mgs per day when taken once per week at 250. A difference of 13
Sus releases between 17-33; a difference of 16.
The prop in the difference makes up between 1-6 of that 17-33. That is 5%-18% of the highest and lowest amount released into the blood stream daily.
The variance between sus and E is not as drastic as the parrots say on the internet, and just over 10% of the variance is attributed to the prop. You will get no better explanation with numbers involved that are in favor of pinning sus according to its half life. Sus at a TRT dose can be pinned once per week as it behaves very similarly to E or C. If you ask any proponent for increased pin schedules for sus, they can never explain why except that "It has to be pinned according to its half life" or "because it is so unstable" You can see from the calculations above that neither is true given these circumstances.
