[MCU] What would be the timeline of Super-Soldier research now?

From the top of my head right now, I tried to trace

Erskine original formula, used on Red Skull and perfected on Steve - ultimately lost. 

The concoction Zola used on Bucky - which I'm not sure was ever written down anywhere - still in Bucky and probably unreplicable. 

With Zola being snatched by Americans, it's likely that the his research was fused with attempts to replicate Erskine formula. 

With release of Falcon and Winter Soldier it seems >!Isaiah Bradley!< fits in this time frame - while the research that used on him was unspecified, he was probably the ultimate victim of continued Zolas experiments. 

It's also unclear what sort of research went into the serums that Howard Stark had on him, which were ultimately stolen by Winter Soldier and used on a bunch of HYDRA goons. It was definitely later results and seemingly universally successful, since none of the test subjects died on HYDRA side. 

It's also unclear what sort of serums Emil Blonski got doused with, they seemed to be on ice for a considerable amount of time, and since they had some really odd side-effects on his body, I think it probably wasn't the Stark version, and probably one of Zola's experimental ones. Maybe. 

And now in the end we have the perfected Power Broker serum, which seems to have  no side effects... Well, at least not obvious ones. And this one >!seemingly also lost now. !<

Am I missing something?

Banner made his own version of the serum, which is what him and (probably) Blonsky were given. He didn’t know it was the super soldier serum though, he thought it was supposed to make people resistant to radiation. Because he thought it was for radiation resistance, he used gamma radiation with it and that combination was what turned him into the hulk. Blonsky presumably then got that same serum minus the radiation.
