as a salt of at least one pharmaceutically acceptable acid, wherein the pharmaceutically acceptable acid has the following formula:

2. A method for making a pharmaceutically acceptable salt, the salt comprising the following compound:

as a salt of at least one pharmaceutically acceptable acid, wherein the acid has the following formula:

the method comprising contacting the compound and at least the acid, to form the salt.

3. A pharmaceutically acceptable composition, comprising the following compound:

as a salt of at least one pharmaceutically acceptable acid, wherein the pharmaceutically acceptable acid has the following formula:

and at least one pharmaceutically acceptable carrier.

4. A method for making a pharmaceutically acceptable composition, the composition comprising the following compound:

as a salt of at least one pharmaceutically acceptable acid, wherein the pharmaceutically acceptable acid has the following formula:

and at least one pharmaceutically acceptable carrier;

the method comprising contacting the salt and the pharmaceutically acceptable carrier, to form the composition.

5. The pharmaceutically acceptable salt of claim 1 , wherein the pharmaceutically acceptable salt is a mono salt, having a guanylhydrazone:counterion ratio of 1:1.

6. The pharmaceutically acceptable salt of claim 1 , wherein the pharmaceutically acceptable salt is a di salt, having a guanylhydrazone:counterion ratio of 1:2.

7. The pharmaceutically acceptable salt of claim 1 , wherein the pharmaceutically acceptable acid salt is a tri salt, having a guanylhydrazone:counterion ratio of 1:3.

8. The pharmaceutically acceptable salt of claim 1 , wherein the pharmaceutically acceptable salt is a tetra salt, having a guanylhydrazone counterion ratio of 1:4.

9. The pharmaceutically acceptable composition of claim 3 , wherein the pharmaceutically acceptable salt is a mono salt, having a guanylhydrazone:counterion ratio of 1:1.

10. The pharmaceutically acceptable composition of claim 3 , wherein the pharmaceutically acceptable salt is a di salt, having a guanylhydrazone:counterion ratio of 1:2.

11. The pharmaceutically acceptable composition of claim 3 , wherein the pharmaceutically acceptable salt is a tri salt, having a guanylhydrazone:counterion ratio of 1:3.

12. The pharmaceutically acceptable composition of claim 3 , wherein the pharmaceutically acceptable salt is a tetra salt, having a guanylhydrazone:counterion ratio of 1:4.
