Prof. Vladimir Khavinson’s bioregulator peptides — Epitalon, Pinealon, Prostamax, and a family of other short-chain compounds — represent four decades of Russian geroscience that Western researchers are now engaging with seriously.

This comparison breaks down their mechanisms, selectivity profiles, and distinct research applications to help investigators understand what each compound brings to the table.

A research guide on PT-141 (Bremelanotide), covering MC1R–MC5R receptor system overview, hypothalamic-limbic circuit activation, and 2026 melanocortin research landscape.

Dihexa doesn’t fit neatly into any of the existing peptide categories researchers typically work with. It’s not a neurotransmitter precursor like much of the racetam-adjacent literature. It’s not a growth factor receptor agonist in the conventional sense. The origin story is worth knowing. Joseph Harding and Don Benson’s laboratory at Washington State University had been […]

Getting a handle on the longevity peptide landscape in 2026 is genuinely harder than it was five years ago. More compounds, more papers, more mechanistic complexity — and frankly, more noise mixed in with the legitimate findings. Some things that looked promising in 2020 haven’t replicated cleanly. Other compounds that were being largely ignored by […]

The peptide research landscape has shifted considerably over the past several years. CagriSema is one of the more compelling answers to that question. It pairs cagrilintide, an amylin analogue, with semaglutide, the well-characterized GLP-1 receptor agonist, into a single co-formulated compound. The rationale is straightforward on paper — hit two distinct receptor systems simultaneously and […]

Peptide research rarely happens in a vacuum. The body—or a cell culture in a petri dish—is a symphony of overlapping signals. So the logical question becomes: what happens when researchers combine peptides that target complementary mechanisms? That’s the central premise behind peptide stacking in a laboratory context. It’s not a new idea. Combination approaches have […]

AOD 9604 occupies a fascinating corner of peptide research — a molecule small enough to synthesize reliably in the lab, yet structurally derived from one of the most complex hormones in the human endocrine system. What makes it particularly compelling? AOD 9604 isolates just the C-terminal fragment responsible for lipid-related activity, essentially giving investigators a […]
