o.k. so durabolin and deca durabolin are not the same.
As for the Sus....this is what i found on Decanoate:
Decanoate: Chemical Structure C10H20O2.
Also referred to as decanoic acid; capric acid; caprinic acid; decylic acid, Nonanecarboxylic acid. The Decanoate ester is most commonly used with the hormone nandrolone (as in Deca-Durabolin) and is found in virtually all corners of the world. Testosterone decanoate is also the longest acting constituent in Sustanon, greatly extending its release duration. The release time with Decanoate compounds is listed to be as long as one month, although most recently we are finding that levels seem to drop significantly after two weeks. To keep blood levels more uniform, athletes (as they have always known to do) will follow a weekly injection schedule.
On Undecanoate:
Undecanoate: Chemical Structure C11H22O2.
Also referred to as Undecanoic Acid; 1-Decanecarboxylic acid; Hendecanoic acid; Undecylic acid. Undecanoate is not a commonly found ester, and only appears to be used in the nandrolone preparation Dynabolan, and oral testosterone undecanoate (Andriol). Since this ester is chemically very similar to undecylenate (it is only 2 hydrogen atoms larger), it has a similar release duration (approximately 2-3 weeks). Although this ester is used in the oral preparation Andriol, there is no reason to believe it carries any properties unique of other esters. Andriol in fact works very poorly at delivering testosterone, bolstering the idea that oral administration is not the idea use of esterified androgens.
As for Durabolin as you have stated:
Phenylpropionate: Chemical Structure C9H10O2.
Also referred to as Propionic Acid Phenyl Ester. Phenylpropionate will extend the release of active steroid a few days longer than propionate. To keep blood levels even, injections are given at least twice weekly. Durabolin is the drug most commonly seen with a phenylpropionate ester (nandrolone phenylpropionate), although it is also used with testosterone in Sustanon and Omnadren
Sus:
Substance: Testosterone propionate 30 mg, Testosterone phenylpropionate 60mg, Testosterone isocaporate 60 mg, Testosterone decanoate 100 mg
But as for Deca Durabolin and Durabolin:
In the old 'WAR 1996', The story goes that Organon first came out with 'Durabolin', then decided to make a roid that would last longer(either longer or stonger), that's when they came out with 'DECA Durabolin which added the newer ester 'Decanoate'. Which both added a higher anabolic potential and longer half life, infrequent injections as opposed to the earlier 'Durabolin'. So it seems that durabolin can be considered a faster acting nandrolone.
Someone correct this if this is wrong.
