Welcome to Pharma Tides Learn — the peptide research library
Why we built a dedicated long-form research library for peptide researchers — and what to expect from it.
Peptide Research, Decoded
An evidence-led library of every research peptide we supply.
Mechanism. Half-life. Receptor targets. Regulatory framing where it matters. The state of the current research and what it actually means at the laboratory bench — written and kept up to date by the Pharma Tides research team.
Peptide-by-peptide
Every research peptide we supply gets a dedicated page covering its mechanism, receptor targets, half-life and dosing context drawn from the published literature.
Research updates
Plain-English summaries of new peptide literature, trial read-outs and longevity science — with regulatory context where it matters, posted whenever something genuinely useful is published.
Honest framing
We flag what is solid, what is still emerging and what is outright speculation, so researchers can read the field instead of the marketing.

Regenerative5 min
BPC-157 — Mechanism, Evidence and Half-Life
A 15-amino-acid fragment derived from a human gastric protein and the most-studied 'body-protective' peptide in animal models. What the published literature actually shows and what it still does not.
- Half-life
- ~4 hours (subcutaneous, animal models)
- MW
- 1419.5 g/mol
Aesthetic4 min
Melanotan-2 — A Synthetic Melanocortin Agonist
A truncated cyclic analogue of α-MSH developed at the University of Arizona in the 1980s. A look at its melanocortin pharmacology and pigmentation effects for the research bench.
- Half-life
- ~1 hour (subcutaneous, animal models)
- MW
- 1024.2 g/mol
Metabolic5 min
Retatrutide — The Triple Agonist Re-Defining the Incretin Class
A GLP-1 / GIP / glucagon triple receptor agonist with the most dramatic weight-loss read-outs in any incretin trial to date. Mechanism, the published evidence, and what the literature still does not know.
- Half-life
- ~6 days (humans, phase 2 PK data)
- MW
- 4731.4 g/mol
Regenerative4 min
TB-500 — Thymosin Beta-4 Fragment Mechanism and Evidence
A synthetic fragment of thymosin beta-4, the actin-binding protein that orchestrates cell migration. The cleanest mechanism story of any 'recovery' peptide.
- Half-life
- ~2 hours (active fragment, animal models)
- MW
- 888.0 g/mol (TB-500 fragment) / 4960 g/mol (full TB4)
Metabolic5 min
Tirzepatide — The First Dual GIP / GLP-1 Agonist
An engineered 39-residue peptide that activates GIP and GLP-1 receptors with a single molecule — the first approved drug to do so, and the new benchmark for incretin pharmacology.
- Half-life
- ~5 days (humans)
- MW
- 4813.5 g/mol
