Although it's available in some parts stores (assume it's the same formulation as shops have) BG44k is not really an "off the shelf" cleaner. I've had two separate shops tell me it's effective. Both owner's opinions I trust. That's why I recommended it.
Anecdotally, I've also used Chevron/Techron stuff about twice a year since buying my car. About two years ago I sent my injectors in for cleaning and flow testing at 90k miles. IIRC I gained less than 2% from before to after on the bench.

Pulling the injectors is premature IMO.
