I guessed it for a Sandoz or Watson, and only cause I couldnt remember which bottle looked like what. You are correct. That is an interesting note if indeed legit pharm grade. Pharm grade test is 5%BA and 20%BB accross the board. I also note it states "as a preservative" Which is kinda funny to say that... 0.9% is typical for BAC water and any solution that needs some simply microbial inhibiting factor. That is all. So I am guessing the Deca has some other properties that dont require so much.
The BA typically provides for:
(1) Mild bacterial inhibitor (in case you contaminate while using) State "preservative effect" I am guessing.....
(2) Even 5% wont kill shit pre-existing.
(3) It also helps provide for dilution properties_ Secondary solvent (the oil is the primary solvent)
(4) Finally it is actually a mild anesthetic contradictory to every idiot out there selling BA as the PAIN DEVIL

. The only pain one feels from BA is immediate stingy slght burn, and it would have to be up arount 10%
The BB provides moreso as a preservation than the BA:
(1) BB is presevative
(2) Dilutant _ a secondary solvent
(3) IMPORTANT - Interaction with ester to create the "depot" and make it stick in muscle for 2-3 days prior to fat saturation. It actually synergizes with nastier esters to create the nice swollen golf ball effect...
Just some old stuff if mem serves. I just got so tired of all the bullshit gossip... BA can harm and degrade tissue in high enough concentrations and long enough exposure, BUT STOP IT ALL>... ITS THE FUCKING ESTER THAT CAUSES THE PAIN>>> STOP... Sorry for the brief rant...
On a final note. High levels of BA are only utiltized to Stuff/supersaturate MASSIVE amounts of powder into a medium of oil by increasing the solutions abilty to retain more in solution, AND FOR IDIOTIC CONCOCTIONS like T400 etc... The problem with those is that they precipitate out of solution as soon as they hit the last crystallized dose in your ass just like the sugar experiment from the 4rth grade. Good for pain gluttens and inefficienianados....

At least thats what I heard......
Seems like its legit. I find it interesting that the BA ratio is 0.9%. Ive always made my gear at 2% BA minimum, and know of people going up to 5. Ive only read and been told not to go lower than 2%, any input homebrewers? Anyone heard of this BA ratio being this low?
