Getting good clean cals is what will help you stay in a positive gain and recovery mode. Having .7g/lb is good enough as long as you get enough cals(clean not junk) to support your energy expenditures and have positive recovery too.
I don't think you need 1g/lb to get gains or maintain them. My recovery has been the same when I am at 80g' a day or 200g a day. I'm 40 and I way 220 @ 6'. I say this cause I'm happy with the amount of muscle I have. Its taken yrs to build and I think alot of people would save money on supps realizing it does. Food is the anabolic of my supp use. I have to admit to the convenience of a good protein or meal replacement shake though.
Food is your best anabolic hands down. Get it dialed in for you. Its worth way more than any supp out there. Once you do that try any supp you want. You will be able to judge how that supp really works then.
I have spent so much money on supps. I have been using food for a few months now without protein at recommended levels( I hit around 70g to 100 g) and I have noticed no issues with recovery, strength, or gains. Course I'm getting enough cals(energy)
I lift and mountainbike so I need to really keep and eye on recovery and make sure its gonna be good. I know all too well what it feels like to be flat and undernourished by just going and hitting the trails. I also work graveyard. Tough going against the body' clock. Really can effect recovery & gains too.
Personally Whisper, I'd try the anabolics you are thinking of without your protein(.7g/lb) needing to be higher. Just get enough good cals in there and see what happens. I'm not considering pro-hormones or steroids in my last comment though. I don't use em' and I can't use t-boosters either without negative effects to my prostate.
