Like others said that is horrible but expected from a GP.
You'd probably end up feeling worse if you did that protocol.
if he's recommending 1 shot every 2 weeks he'll probably never increase it to a level/frequency where you'll be optimal. So you could try to self medicate and if your levels come back to high and your doc cuts you off not really a big deal as he doesn't know what he's doing in the first place so no loss to you.
But ultimately since you don't have alot of experience I'd just go with a try clinic at first to learn then do what you want when you feel comfortable like
