About Maddog Peps

At MADDOG Peps, we bring military precision to every vial we produce. As a proud veteran-owned company, we’re committed to delivering premium-grade research peptides with unmatched reliability, transparency, and consistency.

We built MADDOG Peps after seeing far too many inconsistent, low-quality suppliers in the peptide space. So we created a brand grounded in integrity, discipline, and the high standards we lived by in uniform. Every order is handled with care, packaged securely, and shipped fast — because excellence is never optional.

Whether your focus is research, performance, or recovery studies, we’ve got your six.

Join the MADPACK and be part of a community built on strength, loyalty, and a commitment to doing things the right way.

Strength. Loyalty. Quality.
That’s the MADDOG Promise.
