HSA and substanially equal periodic payments?

[PeachFuzzInVA]

Seems I can't find an answer anywhere, leading me to believe the answer is likely no, but I'll see if anyone here may know for sure. I have an HSA through my employer to go along with our high deductible health plan. Upon early retirement, do you have the same opportunity to take substantially equal periodic payments like you would with a 401k, or do the funds have to be used strictly for medical purposes before official retirement age?

Medical reimbursement, disability, age 65, or early withdrawal penalty.

These things aren't intended to be retirement funds. They just work out that way sometimes.

Unless there's a legal market in repurchase agreements for medical supplies that I don't know about.
