Rego is good stuff mate, i use rego rapid instead of the normal rego recovery. Plenty of protein & carbs and lots of rapidly absorbed pre-digested good proteins to bounce you back to life!
I'd start off by trying the basic stuff – and if you find yourself still needing "that little bit more" – try the Rapid.
If your one of the people who can't stomach the SIS, then the Torq recovery is also a good investment.
Everything i have tried for recovery has had pretty similar effects, it's just personal preference on a) what is palatable and doesn't make you want to vomit, and b) what agrees with your gut and doesn't cramp you up and leave you on the council gritter for an hour at a time.
Good luck fella…… 😉
