5 peptides everyone
should understand.

Your stomach makes a tiny protein that heals damage. This is the synthetic version.

The most researched healing peptide with over 100 animal studies. Unique because it's stable in stomach acid — one of the only peptides you can take orally. If you're dealing with any kind of tissue injury, this is where most people start.

The Ozempic/Wegovy drug. Mimics your gut's "I'm full" hormone.

FDA-approved as Ozempic and Wegovy. 15% average body weight loss in clinical trials. Tens of thousands of patients studied. The most validated peptide therapeutic in modern medicine. If you're interested in metabolic peptides, understand this one first — everything else (Tirzepatide, Retatrutide) builds on it.

A copper molecule in your blood that resets gene expression. You lose most of it by 60.

A naturally occurring copper peptide that declines with age. Research shows it modulates over 4,000 genes, shifting expression patterns toward younger profiles. Used topically in skincare (with real data) and researched as an injectable for systemic anti-aging. The broadest evidence base of any longevity peptide.

A nasal spray that fertilizes your neurons. Prescription drug in Russia for 30 years.

A prescription nootropic used in Russia since 1994. Rapidly upregulates BDNF — the brain's primary growth factor for new connections. Intranasal, fast-acting, and one of the few cognitive peptides with actual clinical use history (albeit in Russia, not the US).

The cleanest way to boost growth hormone. Does one thing with no side effects.

The most selective GH secretagogue — it stimulates growth hormone release without touching cortisol, prolactin, or appetite. The "default choice" for GH protocols. Usually combined with CJC-1295 (no DAC) for synergistic release. Understand Ipamorelin and you understand the entire GH secretagogue category.
