BulkGLP offers a full range of research-use peptide pen kits, providing precision hardware systems for laboratory applications.
Our pens are compatible with any peptide and ship with sterile vials, capped needles, and protective cases for organized handling.
Whether you require a Retatrutide Pen, Tirzepatide Pen,
Semaglutide Pen, or a Universal Pen Kit,
each option is designed to support reliable, repeatable workflows.

Universal Research Pen Kit

The Universal Research Pen Kit is a hardware-only option that includes a precision pen,
hard shell storage case, 5 empty vials, and 20 sterile needles. This configuration is peptide-agnostic, making it suitable for
research involving GLP-1 analogs (semaglutide, liraglutide), dual GLP-1/GIP agonists (tirzepatide),
tri-agonists (retatrutide), and peptide fragments such as BPC-157, TB-500,
GHK-Cu, KPV, and CJC-1295.

Peptide-Specific Pen Kits

For labs preferring pre-bundled solutions, BulkGLP supplies peptide-specific pen kits that include the selected compound, pen hardware, sterile vials, and case.
Each kit is verified by independent HPLC testing for purity and identity.

• Retatrutide Research Pen Kit (20mg) — GLP-1/GIP/glucagon tri-agonist research.
• Tirzepatide Research Pen Kit (30mg) — GLP-1/GIP dual agonist research.
• Semaglutide Research Pen Kit (20mg) — GLP-1 receptor analog research.
