Took me 250 hits over 5ish minutes to solo unbooosted, i'd reccomend using the get hit + heavy method with aegon and also what Bittersteel said. Also, Im pretty sure his regen is stronger depending on power lvl so I personally always baited sp1.
Wolverine in RoL is pre-nerf, so his healing isn't based on power level or you could use magik/psylocke and power lock him at 0 power meaning no regen. He just has a flat 3k and 9k heal I believe.
Just beat Wolvie last night and he still regens on crits. I had to close out game a few times because I had him below 20% and he started healing to 50%.

Do parry M then pause then L
If you don’t crit then stop, you can hit into Wolv’s block and do a crit, then your next hit will be a -100% AAR hit
Be aware of your first hit after a revive too, that's possible to activate a regen.
I did parry, MM until my combo was around 100 hits then I just played like normal, heavy/hit into sp2, ignoring the 3k heals.
Quit out once when he did a big regen at about 20%.
