Dihexa FAQ: Reconstitution, Storage, Purity & Sourcing
3 min read•Published 2025-11-17•Quality Peptide USA Research
Dihexa (PNB-0408 / N-hexanoic-Tyr-Ile-(6) aminohexanoic amide) is a small peptide derived from angiotensin IV. It is studied in synaptogenesis and cognitive research models for its reported potency in promoting hepatocyte growth factor (HGF) / c-Met signaling.. This guide covers faq for researchers for Dihexa — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.
Is Dihexa research-grade?
Yes. Every batch of Dihexa sold by Quality Peptide USA is released to a ≥ 99% HPLC purity specification, with mass-spec identity confirmation and LAL endotoxin testing on every lot. The certificate of analysis is published on the product page.
How should Dihexa be reconstituted?
Reconstitute Dihexa with bacteriostatic water (0.9% benzyl alcohol). Inject the water down the inside wall of the vial — do not inject directly onto the lyophilized cake. Swirl gently until fully dissolved. Refrigerate at 2–8°C after reconstitution.
What is the reported half-life?
Extended oral bioavailability profile (research models) Half-life figures from in-vitro models are not directly transferable to ex-vivo or in-vivo systems.
Where is Dihexa synthesized?
Dihexa is synthesized in the United States and ships from a US facility. No overseas drop-shipping, no customs delays, full domestic cold chain.
What testing is performed on each batch?
RP-HPLC purity (≥ 99% spec), ESI / MALDI-TOF mass spectrometry, Karl Fischer water content, LAL endotoxin screen, and bioburden. All results are published on the per-batch certificate of analysis.
Can Dihexa be stacked with other peptides?
Many research protocols pair Dihexa with complementary peptides — the Glow stack for dermal models, the Wolverine stack for tissue repair, or GHRH/GHRP secretagogue blends for somatotropic studies. Review the published literature for your specific endpoint before designing a stacked protocol.
