We serve the Texas Medical Center, researchers at MD Anderson, Baylor College of Medicine, and Rice University, and compounding pharmacies and wellness clinics throughout Greater Houston. Houston submissions are mostly GLP-1 peptides and research compounds sent in for independent purity and identity verification before use.
Houston submissions arrive from two very different sources. The first is the Texas Medical Center corridor, where groups at MD Anderson Cancer Center, Baylor College of Medicine, UTHealth Houston, Houston Methodist Research Institute and Rice University send custom-synthesised sequences for identity and purity confirmation before an in-vivo run. Those samples are usually small, sometimes a single vial, and what matters to the submitting lab is method detail: we state the column, gradient and detection wavelength on the Certificate of Analysis rather than reporting a bare purity figure.
The second source is commercial. Compounding pharmacies, men's health practices and wellness clinics across Greater Houston, The Woodlands, Sugar Land, Katy and Pearland send GLP-1 material for independent verification, most often because a client or a quality reviewer will not accept the supplier's own certificate. For those submissions we run purity by RP-HPLC, confirm molecular weight by LC-MS, and add net content when the label claims a specific milligram fill.
Logistically Houston is straightforward. Bush Intercontinental is a major FedEx and UPS air hub with late evening cutoffs, so a package handed over in the afternoon is logged in Sun City Center the next business morning. Ground service from Houston takes three to four days, which is fine for stable lyophilized powder but not for anything already reconstituted.
Transit
One business day by FedEx or UPS overnight from anywhere in Greater Houston.
Humidity
Gulf Coast humidity degrades exposed lyophilized peptide — keep vials sealed and add a cold pack in summer.
Hurricane season
June through November, avoid Thursday and Friday pickups so a storm delay does not park your samples over a weekend.
