From your limited message, I can only suggest to do your DD and understand how the body operates better. Proteins are not the source of muscle gains - Proteins are made of smaller chain amino acids. To ingest proteins would only be a cause for your body to use energy to break these proteins down into smaller products that your body can actually use for muscle growth. To put it simply - If you are going to build a beautiful house, would you buy a pre-built house to then take apart and then reassemble it in the form you'd like?
As well, the "workers" read: enzymes, are vital to the construction of your muscle. Without the proper enzymes support, the house won't be built or be poorly put together.
I'd look into the Iron Men and other extremely large/strong individuals that have been either vegan/vegetarian at least during training... There is quite an extensive list of ppl who you wouldn't have expected that are vegetable made muscle. Bill Pearl is one... and there are quite a lot of sources for info from vege/vegan bodybuilders with a simple online search. Protein consumption is a huge myth purported by the money-mongers within the medical/food industries.
