Lately, I've been seeing several members (particularly some newer members), who, in their enthusiasm for the board have been going around shouting at people that it is a absolute necessity to inject sustanon EOD. Their reasoning, while seemingly logical, but largely parroted, is that sust must be injected more frequently to "take advantage" of the short ester it contains, namely, prop.
Hopefully this thread will serve as a corrective to that mistaken notion.
First, let's remember that sust was originally designed (yes, designed, ie, created for a specific purpose) for HRT/TRT patients, where the propionate ester in sust would provides a quick burst, while the long and medium esters release throughout the week.
Next, a quick glance at the chemical composition of sust:
30 mg prop, 60 mg isocaproate, 60 mg phenylpropionate, and 100 mg decanoate. The total of which is 250mg.
Now, as we already know, release rate of the ester is determined by its weight (ie, the number of carbons in the ester). In the case of sust this is:
prop: 3, iso: 6, phenyl:9, and deca: 10.
So, the decanote ester is a pretty heavy ester and it makes up 100mg of sust with phenyl and iso close behind, which tells us, if it's not already clear, that
injecting twice a week is quite satisfactory for sust.
If someone still isn't convinced, and wants to further press the issue by arguing again that the prop ester won't be "fully utilized" or it will be "wasted", I would refer them again to the structure of sust. Since the prop and phenyprop ester release in sust not separately, but concomitantly, their release for the first four days is strikingly similar to a sinlge ester test (again, making twice a week injection ideal for BB purposes!). And again, this is precisely why sust was originally
designed the way it is.
The conclusion is that the argument for shooting sust EOD or ED
because of the prop ester is actually just incorrect. Sust was designed to be injected once a week, twice a week is quite fitting for a BB, but EOD is simply a preference.
Be safe and happy growing:
