B-but you ignored my post above. And how long it did it take to create those viruses? How long were they sitting in a freezer somewhere before someone had a use for them?
Unless you can provide proof that they were not even invented yet and the concept not even thought of, and then they just did it all in a couple of days, you don't have a case.
And even if you did, you'd have to explain how they could invent this, then mass-distribute it, then transport it across the thousands of planets across the galaxy that are under siege, then they'd have to augment it to be used in a vacuum (considering Tyranid don't need to breathe), then they'd have to re modify it every couple of days every time the Tyranid assimilated a new alien species into their gene pool, each time becoming harder and harder because as they share traits with the host gene the poison would then affect those who share that gene, meaning that as human tyranids are affected by it humans themselves would be susceptible, etc. etc. And every time they modified it they'd have to re mass distribute it etc.
And again... the Tyranid can double their forces in 2 and a half days... so day one they have 3 billion forces, you gas them, two and a half days there's a billion more with a resistance to the bio-weapon you just created, two and a half days later there's a billion more with a new resistance, and this is of course happening with only one fleet; there's multiple grand fleets in the Tyranid armada mind you which means that the Empire would basically have to create and distribute a poison for each type of life form in the galaxy, as the Tyranid have enough forces to assault multiple star systems and can thus assimilate multiple life forms into the gene pool... and the Empire would have to do all of this while keeping up with the Tyranid's incredible reproductive rates...
