Which analysis do I need?
Up to three questions, one recommendation.
Peptide macromolecule characterization
This division identifies the structure and assays the concentration of biologically active peptide polymers in complex matrices, including high-demand active ingredients such as semaglutide and tirzepatide, across lyophilized, injectable, or nutritional formulations. High-resolution methods deliver objective technical findings, essential for batch validation and purity verification.
Chromatographic assays of regulated hormonal compounds
This section screens, separates, and quantifies synthetic anabolic and androgenic agents in solid, liquid, or oil-based samples. Precise fractionation delimits the exact chemical identity and dosage of the steroids present, documenting cross-contamination risk or undeclared substances.
SARMs and related compounds
Identity confirmation and dosage quantification for selective androgen receptor modulators, using the same GC-MS, NMR, and HPLC methods applied across our other compound categories.
SERMs and related compounds
Identity confirmation and dosage quantification for estrogen receptor modulators, using the same GC-MS, NMR, and HPLC methods applied across our other compound categories.
Sexual health pharmaceuticals
Independent identity, purity, and quantification analysis of sexual health pharmaceutical ingredients and blends, on the sample submitted.
Ancillary & supportive compounds
Identity confirmation and dosage quantification for cardiovascular, metabolic, and thyroid-support compounds commonly used alongside other research protocols, using the same GC-MS, NMR, and HPLC methods applied across our other compound categories.
