So, does Muscle Milk affect penis size? Hahaha! I find the question laughable but since it gets asked so much on various forums, it must be a concern for a number of men out there.

First what is muscle milk? Muscle Milk is a popular muscle building protein supplement created by CytoSport, a company founded by the father and son team of Greg and Mike Pickett.

Like most protein drinks Muscle Milk is primarily made from whey protein—the protein found in milk but also includes casein. This is the reason that it is said to be ‘evolutionary’.

Whey protein is absorbed into the blood stream relatively fast but also gets burned up just as fast and so much of the whey that one consumes after a workout will not actually be used in protein synthesis.

On the other hand, casein takes longer to get absorbed but also stays in the body much longer. This duality of having both quick absorption and slow release proteins improves the muscle building process since some form of protein will always be available—the whey during the first few hours and casein over the next several hours.

The reasoning is sound but whether this is what actually happens in practice is less clear. The three different studies I have seen all seem inconclusive. All I can say is that Muscle Milk is at least as good as any regular whey protein.

It derives its name ‘Muscle Milk’ from the effect that a human mother’s milk has on a baby i.e. nourishing and providing immunity.

In addition to the proteins Muscle Milk contains compounds like bovine colostrum which has important anabolic properties.

Colostrum is the milk produced by a human female 24-48hrs after birth. Bovine colostrum is from cows and is thought to have even more of these anabolic (growth) properties.

And now the all important question: Does Muscle Milk affect penis size?

As I noted earlier the question is laughable but on closer consideration maybe it is plausible. After all it contains anabolic properties that aid in muscle growth. Shouldn’t they aid in penis growth as well?

Unfortunately not. The muscle growth that results from taking Muscle Milk only happens when you engage in intense training. Intense training causes micro-tears to your muscle tissues.

The healing of these micro-tears aided by excess protein calories (from Muscle Milk) is what actually causes growth.

There are no micro-tears caused to the penis and therefore no increase in size. Also understand that the penis is mostly made up of cartilage and fibrous tissue.

Even if you somehow managed to subject it to the kind of intense training you do to your biceps and chest, it would not grow.

So again, let me be crystal clear. Muscle Milk does not affect penis size.
