Peptides, prescribed properly.
Anyone can sell peptides. Almost nobody prescribes them properly. We organize every molecule by the strength of its human evidence, use pharmacy-grade product only, and track results in your bloodwork, because the peptide is 5% of the result. Tracking is 95%.

Why people start here instead of a peptide website: screening before anything higher-risk, a licensed 503A/503B pharmacy instead of grey-market vials, and bloodwork that tracks effectiveness and safety instead of hoping. The peptide is 5% of the result. Tracking is 95%.

Peptides 101: A Physician's Honest Guide.
A clinician-written, jargon-free briefing on what each peptide actually does, what the human evidence really says, and the exact biomarkers to track before you spend a dollar. No hype, no grey-market sales pitch: just the honest version, from a physician who publishes on this.
- The five evidence tiers, and which peptides we won't sell you
- What to measure first, so a peptide accelerates health instead of dysfunction
- How GLP-1s, BPC-157, MOTS-c and NAD+ fit into a tracked plan
Ranked by evidence, not by hype.
Every peptide we prescribe sits in a tier based on the strength of its human evidence. Tier 5 exists so you know what we won't sell you.
| Tier | Category | Evidence | Molecules | What we track |
|---|---|---|---|---|
| 1 | Metabolic Foundation (GLP-1) | Strong human evidence | Semaglutide, tirzepatide | HbA1c, fasting insulin, hsCRP, body composition, epigenetic age |
| 2 | GH Secretagogues | Good, requires oversight | Tesamorelin | IGF-1, glucose & insulin (HOMA-IR), HbA1c, hsCRP |
| 3 | Healing & Recovery | Limited human data, short course only | BPC-157, TB-500 | Pre/post ultrasound, inflammatory markers, cancer screening clearance |
| 4 | Mitochondrial Support | Emerging, measure before you treat | SS-31, MOTS-c | Metabolic & thyroid panels, hormones, early-detection screening |
| 5 | Experimental | Not recommended | Injectable GHK-Cu, Melanotan I/II | Not offered until credible human evidence exists |
Why Tier 1 leads: a 2026 double-blind RCT in Nature Communications found semaglutide slowed the pace of biological aging by roughly 9% on DunedinPACE. That's the calibre of evidence we anchor to. On Tier 3, our own published analysis found a real efficacy signal for BPC-157 alongside a real neuropsychiatric risk, so it's short-course only, screened and monitored. Read the BPC-157 analysis →
We'd rather lose the sale than recommend something we can't stand behind. Research-phase compounds are not FDA- or Health Canada-approved for human use; eligibility is determined case by case with full informed consent.
