Longevity, Skin & Cognitive Peptides
Skin cosmetics, cognitive peptides, sexual health, sleep, and mitochondrial topics — mixed evidence, careful Canadian framing.
Detail pages coming soon Individual compound profiles will be published after clinical review.
Who this category is for
Patients curious about skin quality, focus/anxiety-adjacent nootropics, sleep peptides, sexual desire therapies, or “longevity” mitochondrial agents. Expectations often come from social media; we slow the conversation down to mechanism, evidence grade, and whether a labelled medicine already exists.
How this differs from other peptide categories
Unlike GLP-1 weight-management medicines (strong RCTs) or GH secretagogues (endocrine axis), this category spans cosmetics, neurology traditions, sexual medicine, and highly experimental longevity claims. Topical cosmetic peptides are not the same as injectable research chemicals. Labelled sexual-medicine peptides (where available) are not interchangeable with gray-market “wellness” vials.
Compounds on the education menu
| Compound | Evidence tier | Notes |
|---|---|---|
| GHK-Cu | C topical / D injectable | Cosmetic vs injectable contexts are different risk and evidence worlds |
| Epitalon | D | Longevity marketing often ahead of rigorous human evidence |
| Matrixyl | B–C | Topical cosmetic peptide — not an injectable therapy |
| Selank | D–C | Anxiety/nootropic tradition; limited Canadian authorization |
| Semax | D–C | Cognitive/neuro tradition; limited Western pivotal proof |
| PT-141 (Bremelanotide) | A (US labelled) | Vyleesi — confirm Canadian availability and indication fit |
| SS-31 (Elamipretide) | A Barth only / D wellness | Approved Barth syndrome use is not the same as gray-market “SS-31” wellness vials |
| DSIP | D | Sleep peptide with limited supporting evidence |
Safety snapshot
Common pitfalls
Assuming a U.S. label applies in Canada; treating topical cosmetic data as proof for injectables; buying mitochondrial or nootropic peptides as RUO powders; ignoring nausea/flushing profiles of melanocortin agonists.
Tri-Health approach
Separate cosmetic, labelled sexual medicine, and experimental longevity lanes. Prefer sleep hygiene and cognitive fundamentals. Escalate only with consent, monitoring, and lawful pharmacy sourcing when a therapy is appropriate.
How Tri-Health approaches this category
- Define the goal — skin, sleep, cognition, libido, or “anti-aging” curiosity.
- Offer higher-evidence paths first (skincare basics, sleep medicine, sexual-health workup, metabolic care).
- Explain SS-31 / Forzinity nuance: Barth-indicated therapy ≠ wellness vial.
- Discuss PT-141 only in sexual-health context with regulatory clarity.
- Decline unsupervised experimental stacks marketed for longevity online.
