Batch B003
Brief Description

Full-length 44-amino acid GHRH analog with a trans-3-hexenoic acid modification that improves stability and receptor binding. One of the most extensively studied GHRH analogs in published literature, with research focused on visceral adipose tissue, lipodystrophy models, IGF-1 axis modulation, and cognitive function in aging populations. For research use only — not for human consumption.

Batch 002 Transparency Note
Transparency update

Due to recent supply chain and international shipping disruptions, some Batch 002 inventory may include vials produced at different points within our supplier’s production cycle. As a result, researchers may notice minor packaging variations, including differences in vial caps.

These products were sourced from the same established manufacturers we have worked with for ongoing quality and third-party testing. That said, we want to be transparent that Batch 002 may not represent a single uninterrupted production run.

We are already working with our suppliers to strengthen batch-control, packaging, and documentation protocols before Batch 003.
