I don't know what to think anymore. Is this all true? I use GNC pro performance whey protein Isolate and it's not one of those dirt cheap powders like "American pure whey" .

I don't know if the guy's technique was completely accurate or not but even the best brands didn't match up apparently:

IMO, protein powders are horrible for anyone interested in life extension. They raise IGF-1 and increase mtor activity... Strong today, gone tomorrow.

You aren't just criticizing protein powders; you are criticizing protein from whatever source.

Please clarify; are you saying that you should go below minimum RDA levels of protein? Surely not. If you need more protein to hit RDA, is there any reason that whey might not be an appropriate source of some of it?

I'm criticizing protein powders, the purpose of which is to boost protein intake way beyond RDA levels. Whey based powders have high levels of BCAAs (mtor activator) and growth hormone residues. The amino acid profle is designed for growing calves.

Since the key to maximizing longevity seems to be slowing down protein synthesis, supplementing with protein powders might not be the best idea.

You're correct but I really don't want to get into this discussion on this thread if you don't mind.

I created this thread to see if anyone more knowledgeable in performing assays could verify if these claims in the links on my first post hold any truth to them or not.

Maybe if someone has the proper facilities and some spare time they could look into borrowing some samples of friends (or your own) protein powder and test various brands and report back here?

I am going to university in september and I'm going to be learning biotechnology lab techniques and such so I will do it myself if no one else takes up the challenge.

Well I can tell you that my protein powder seems to have been doing a most beautiful job in doing that. I have 17 inch calves at 189lbs 17% bodyfat.

Just joking mate, I knew what you meant i just couldn't resist.

What do you think of soy or pea protein powders? (not whey)

Or how about egg white protein powders?

they look good on paper, but I am yet to find any that have a taste tolerable for regular use

To what end? If building muscle, whey has no competition. Soy would be at the bottom.

Hydrolyzed whey for muscle building, perhaps with a dash (3+g of leucine) after hard workouts.

Sorry to be slightly off-topic, but I had to reply to this. While protein consumption may generically have those effects, and in isolation those effects are negative for life-extension, these facts are superseded by direct studies of feeding certain types of protein, e.g. BCAAs, to mice which resulted in extension of their life.

One explanation is that the BCAAs increased SIRT1 expression.

[The Immortalist]

Bump for answers on if the so called top protein powder manufactures are indeed scamming buyers.

[TheKidInside]

I believe that most people have an obsession with protein consumption due to brilliant marketing by said supplemental companies. Also, most people have a strange belief that 1 gram per POUND of lean body mass is needed for maintenance/health yet it is .8-1.2 grams per KILO of LBM that's really required/recommended. Up to 1.9 for athletic synthesis. In terms of bio avalability I think a 70% pea 30% rice combvo is amaaaazing. And a company called truenutrition puts out an excellent and palatable version of such.

Anyway, because the goals I've mentioned I easy to hit for vegans and CRONies it works for everyone so I don't see the NEED for protein powders. Even with the pea/rice one I've mentioned I only intake about 10 grams in my "post work out" shake with some coconut water for some little carbs and potassium as the "electrolyte" and it works fine. I train pretty heavily in jiu jitsu and thai boxing as overall fitness, calisthenics/bodyweight stuff or periodization with 531 power lifting etc.

I prefer egg and hemp protein. Whey makes me bloated and increases acne.

Bad methodologies show nothing, unfortunately.

I think this should be a meme, you can do a search, it's called, "the usual nonsense" (=very badly designed studies)

Just from my reading of various forums and research, I would have to agree that excess protein intake (whether from powders or other sources) is not good for life extension. I wouldn't say for sure that it is a negative either. If you want to build huge muscles, well then sure, you will want more protein (from whatever source), and you will want to make sure it is a good protein.

Most evidence points toward lower calories, lower metabolism, less weight, as being the best CURRENT method(s) of slowing aging and extending lifespan. This makes a lot of sense if you give credence to the damage (SENS) theory of aging.

...except that the "higher calories are deleterious to lifespan" evidence is probably irrelevant to us, since none of the animal studies combines higher calories with compensating resistance exercise, so it is not surprising that the excess uncompensated calories would limit lifespan. But consuming more uncompensated calories is not what we are proposing.

Resistance training has never been properly studied in the context of life extension. Certainly the animal studies tell us nothing with respect to weight training, and even if someone could figure out a way to make rats do bench presses, say, their physiology is so different that is is questionable whether that would tell us anything about humans. Almost all the human studies suggest that weight training is overall good for health markers, and anecdotally weight training lets humans maintain a younger appearance for much longer than their sedentary (or even endurance-training) peers.
