It is called "Liquid: Predigested Collagen - Protein" by Solgar.

The ingredients are: Soluble Protein Hydrolysate, Deionized Water, Sorbitol Solution, Citric Acid, Natural Cherry Flavor, Potassium Sorbate and Sodium Benzoate.

Each two tablespoon serving provide:

L-Alanine 1300mg
L-Arginine 1200mg
L-Aspartic Acid 900mg
L-Cystine 10mg
L-Glutamic Acid 1500mg
Glycine 3500mg
L-Histidine 110mg
L-Hydroxlysine 150mg
L-Hydroxproline 1000mg
L-Isoleucine 200mg
L-Leucine 450mg
L-Lysine 650mg
L-Methionine 110mg
L-Phenylalanine 35mg
L-Proline 2300mg
L-Serine 1000mg
L-Threonine 300mg
L-Tyrosine 100mg
L-Valine 350mg

It also has a warning about the fact it contains Phenylketonurics(PKU) since it has L-Phenylalnine. (What is bad about these anyhow?)

Since I know hardly anything about Amino Acid supplementation, it would be helpful if someone could let me know if this product is worth taking or if I should return it to the store and try to find something else.

Protein is amino acids linked to each other. What you need are single amino acids; free amino acids. And because they are acids, they never remain free under normal circumstances; they easily react upon eachother, so that is why real free ammin aids come in an acidic liquid that can only been maintained in glass tubes. they are completely glass, but you can break them at the top, (mostly) breaking without any small pieces braking off.

If the amino acids do not come in a liquid that needs to be maintained in glass tubes, they are notfe amino acids, but 'dirty' protein.

I'm looking for the right amino acid supplement as well since I am extremely active and am looking to increase my lean body mass by a significant amount. Searching on the web I haven't been able to find liquid free amino acids. Here are some links to what I have been able to find :

Gematria on free aminos

One of their products I was thinking of.
The 500mg/$50 better be a typo!

Individual ones in tablets and capsules :
Individual ones in tablets and capsules

More individual ones

Don't know much about this one

If I were to take them in capsule or tablet form I assume I would try to take them in ratios similiar to eggs? The price does not really bother me much. These links seem to be lacking in info a bit. Any ideas on what I should ask them?

Has anyone else found any links?

Once your skin is clear you can try these free (?) amino acids to test whether they cause acne in you or not.

First you only need:
L-methionine
L-cysteine

This because fruits already contain very much of all the other amino acids.
Not until you would take more than 1,000 mg of cysteine and methione daily, you would need to start supplementing with phenylalanine and tyrosine too.
Taking 1,000 mg cysteine and methionine this would already double the protein quality of the protein in 6 kg fruits (over 13 pounds; 1% protein in average fruits).
So, this 6 kg of fruit (including a handful of Brazil nuts, 100 gram dried dates and 100 gram dired figs; 10 gram protein in total) that contains about 67 gram protein, with a protein quality that equals that of soy-protein, now supplies you with as many valuable amino acids to build muscles as 134 gram soy protein!!!

Supplementing over 1,000 methionine and cystein, you would need equally much extra phenylalanine and tyrosine (so equally much minus 1,000 mg):

for example:
taking 3,000 methionine and cysteine, you would need 2,000 mg phenylalanine and tyrosine.
But you better start with 500 or 1,000 mg methionine and cysteine first.

Instead of 500 mg methionine and 500 mg cystein, you can aslo take 1,000 mg methionine only, since the body can easily convert methionine into cystein (not the other way around) according to its needs.

Instead of 500 mg phenyalanine and 500 mg tyrosine, you can also take 1,000 mg phenylalanine, since the body can convert phenylalanine into tyrosine easily (not the other way around).

So, summarizing, if you want to try them, you first only need methionine, and once you want to supplement more than 2,000 mg methionine a day, you would need equally much phenylalanine as the methionine consumed on top of the 2,000 mg.

But again, they may very well cause acne if they are not really free.

PS, if you want to learn more about protein quality and the amino acids in fruits, see http://www.13.waisays.com/protein.htm 

So here the results are less spectacular than in fruit, but this gain (8 to 13 gram "soy" protein extra) is on top of the results in fruit protein. (67 gram "soy" protein extra)

So a total daily supplementation of 2,500 mg methionine will increase the overall protein quality to such an extend that it's effect has the equivalent of 72 to 77 gram additional "soy" protein.
Maybe this one from Solgar is a good try?
Or this one of Solaray, that you had already found ($5.59)
Or this one from Twin Lab ($5.09)($4.62 at Nourishingfoods.com)

Of course you should open the capsules and not take the capsule itself. Best consumed with the fruits.

Please keep us updated about the results of this experiment!!!

If you want to supplement over 2,500 mg methionine, than you need to supplement with additional equal amounts of phenylalanine and methionine (and other ones the more you go up).

Consuming kilos of fruits (what we all do) we absorb about 30 to 65 gram protein from all these fruits in total (depending on your energy requirements)
These protein contain all required amino acids, but they are relatively low in methionine and cysteine, compared to all other amino acids, when compared to how much you need of every amino acid.
By supplementing with methionine you also fulfil your need for cysteine. And not until you supplement over 2,500 mg methionine, other amino acids need to be supplemented too (phenylalanine / tyrosine)

This means that when you eat so much fruits, you can very easily increase their protein quality by taking methionine only, because they are only very low in methionine.

If you would ingest much high quality protein from escargot for example (then you would not need extra protein, but anyway), then you would need to supplement with many different amino acids to increase its protein quality a bit.

so, that is the good thing about the combination fruits and single amino acids; you can very easily increase fruit-protein quality by taking only one: methionine.

Please take a look at http://www.13.waisays.com/protein.htm 
there you see the amounts of essential amino acids listed in 2kg, 4kg and 6kg fruits respectively (at the left) and the required amounts of amino acids (at the right). From this you can clearly see that all amino acids are abundantly present, except for methionine / cysteine.

it's ingredients are:

Enzymatic Hydrolyzed Whole Proteins, Pure Crystalline Fructose, Ascorbic Acid, Natural & ARt Flavors, Artificial Colors, Sodium Benzoate, Potassium Sorbate.

hmm.. do i have the right one? pls advise so i can replace it if it's not... thanks...

btw, all i can see at health food stores are liquid amino acids... is this the same as the liquid free amino acids?
