Research Guides

Everything UK researchers need to know about tirzepatide in 2026 — what it is, research-grade vs Mounjaro, UK status, how to choose a reliable supplier, vial sizes and prices, reconstitution and storage.

Everything UK researchers need to know about retatrutide in 2026 — what it is, its UK status, the Phase 3 research, how to choose a reliable UK supplier, pricing, reconstitution and storage.

Bacteriostatic water is the standard solvent for reconstituting research peptides. This guide covers what it is, how much to add to a vial, how concentration works, shelf life once opened, storage, and how it differs from sterile water.

The Glow Stack is one of the most searched-for peptide blends in the UK. Here is what is in it, why the three compounds are combined, how the ratio works, and how to reconstitute and source it for research.

Across 23–24 July 2026 an FDA advisory committee recommended six peptides — BPC-157, KPV, TB-500, MOTS-C, Epitalon and Semax — for the 503A compounding list, rejecting DSIP. What the vote means, and what it does not.

HGH and HGH Fragment 176-191 are easily confused but structurally distinct. A research-context guide to the difference between the full hormone and the tail fragment, plus what IU means and how it affects reconstitution.

Metabolic peptide research is moving from single and dual agonists toward triple agonists that engage three receptors at once. A research-context overview of the shift, from Tirzepatide to Retatrutide.

BPC-157 and TB-500 are the most commonly paired peptides in research discussion. A research-context look at their different origins, why their mechanisms are studied side by side, and the limits of the evidence.

A plain-English, research-context explainer of the 2026 FDA peptide reclassification: what came off Category 2 in April, what it does and does not mean, and what the July PCAC review decides next.

Research peptides are available in two formats: lyophilised vials and pre-filled multi-dose pens. This guide examines why the two formats carry fundamentally different stability profiles — and what that means for your research.
