Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Thymogen is a synthetic dipeptide made of glutamic acid and tryptophan (Glu-Trp), also known as oglufanide. It was developed in Russia as a compound derived from thymus research and is thought to influence immune cell activity, particularly T-cell function. Its exact mechanism in humans is not well established.

What the evidence shows

Automatic summaryLimited human data

It is not FDA-approved, and no registered human trials are listed. About 97 published papers exist, many of them older Russian-language clinical and lab reports that are hard to evaluate by current standards, so any benefit in humans remains unconfirmed.

This name is shared with unrelated compounds in public databases, so trial and paper counts are not shown here, and the evidence score counts no registered trials. Treat this profile as a starting point only.
