    Testagen

    Description

    A bioregulator peptide supporting male hormonal health and testicular function. Used in male optimization and longevity protocols.

    Dose:2 mg
    Frequency:30 days in a row, 2-3x per year
    Administration Method: SQ
    CategoryBioregulator
    Half-LifeVery short (minutes); typical of Khavinson short peptides.

    Overview

    Testagen is being studied for its role in modulating endocrine function, including possible normalization of thyroid hormones and modulation of male reproductive hormones. It is typically administered in short cycles, not as continuous long-term therapy.

    Mechanism of Action

    Testagen is a synthetic tetrapeptide (Lys-Glu-Asp-Gly, KEDG) proposed as an anterior-pituitary-derived bioregulator that modulates endocrine function, particularly the pituitary-gonadal axis, via a transcriptional 'nudge' rather than sustained pharmacological action.

    Benefits

    • •Male hormones
    • •Testosterone support
    • •Testicular health
    • •Hormonal optimization

    Dosing Notes

    Commonly cited regimens: ~10 mg/day oral or 100-300 mcg/day SQ, in cycles of 10-20 days, 2-4 cycles/year spaced 3-6 months apart.

    Reported Side Effects

    • •Limited human safety data
    • •Possible injection site reactions

    Safety Notes

    Not FDA-approved.
