Tretonin

"Ground Goa'uld?"

- Jack O'Neill

Tretonin is a substance that provides the perfect health of a Goa'uld symbiote in the form of a drug. Using a Goa'uld Queen, the Pangarans used her prim'ta to make symbiotes that they could use to make a chemical capable of giving near perfect health. However, the drug suppresses the natural human immune system, and requires daily injections. Worse, the Queen that was being used was Egeria, Queen Mother of the Tok'ra, who was sabotaging her prim'ta to make the Pangarans stop experimenting on her. After she was able to acquire a host, Egeria gave the Pangarans the key to restoring their natural immune systems, and died.

Though horrified that their Queen had been used in such a manner, the Tok'ra were nevertheless intrigued by the Pangarans use of Symbiotes to make a drug capable of perfect health. When Teal'c and Bra'tac were forced to share Junior between each other after the Ambush of the Kresh'ta, Jacob Carter brought a refined version of Tretonin to the SGC, using it to save Teal'c and Bra'tac, as Junior was overtaxed and died soon after. Teal'c was at first somewhat unsure of its benefits, but soon realized that it was the Jaffa's only hope for freedom from the System Lords. Later, SG-1 gave the Hak'tyl Tretonin so that they would no longer be forced to make raids for symbiotes.

It is indicated later by Major Samantha Carter, that due to the fact that Tretonin replaced the Jaffa's need for a symboite, Teal'c and Bra'tac's symboite pouches had begun to close up. Whether this is the case with all Jaffa remains to be seen.
