BioTech Pharma is a laboratory-research peptide and active pharmaceutical ingredient (API) supplier. Analytical methods and documentation are scoped per product and confirmed on enquiry.
Featured Research Compounds
Our most requested catalogue peptides. Analytical methods and documentation are scoped per product and confirmed on enquiry.

Retatrutide
Triple agonist of GIP, GLP-1, and glucagon receptors — the leading next-generation compound in multi-receptor metabolic research.

Tirzepatide
Dual GIP/GLP-1 receptor agonist peptide studied in incretin-pathway and metabolic research, supplied as a lyophilized powder.

GHK-Cu
Naturally occurring copper tripeptide complex, central to dermal-matrix, collagen-synthesis, and cosmetic-formulation research.

Tesamorelin
Stabilized GHRH analog used in growth-hormone-axis research, engineered for resistance to enzymatic degradation.

In-depth guides to peptide quality, analytical data, manufacturing, procurement, and strategic supply.
Incretin Multi-Agonist Research Peptides: Sequence Design and Analytical Considerations
How single-, dual-, and triple-agonist incretin research peptides differ at the level of sequence engineering, lipidation, and molecular identity — and why those differences complicate impurity resolution, handling, and cross-lot comparability.
GHK-Cu as a Copper-Binding Peptide: Identity, Handling, and Research Context
GHK and its copper complex are not the same material. This profile separates the free tripeptide from GHK-Cu, examines stoichiometry and form, and explains why color and spectroscopy provide context rather than proof of release.
How to Read an HPLC Chromatogram
A working guide to the axes, baseline, integration, and system suitability behind a chromatogram — and the questions a buyer should ask before trusting the number printed on a certificate.
How to Compare Peptide Suppliers Beyond Unit Price
Unit price is the easiest number to compare and the most misleading. Normalizing specification, terms, testing, yield, and lead time turns a spread of quotes into a decision you can defend.

- 01
Solid-Phase Synthesis (SPPS)
Automated Fmoc chemistry assembles the sequence residue by residue on solid resin, with in-process coupling checks.
- 02
Preparative HPLC Purification
Reverse-phase chromatography separates the target peptide from deletion variants and synthesis byproducts.
- 03
LC-MS Identity & Purity Release
Mass spectrometry confirms molecular identity; analytical HPLC verifies the purity specification before release.
- 04
Lyophilization & Filling
The purified pool is freeze-dried into a stable powder, then filled into Type I glass vials.
