How We Verify Every Compound Batch

Every batch of research compounds supplied by Lifestyle Peptides undergoes independent laboratory testing before it becomes available for purchase. Rather than relying on internal quality claims, each lot is sent to a third party analytical laboratory for verification. This process confirms that the material matches its labeled identity and meets the purity threshold expected of […]

Confirming Compound Identity Through Mass Spectrometry

Alongside purity testing, every batch of research peptides undergoes identity confirmation using liquid chromatography mass spectrometry, commonly referred to as LC-MS. This analytical method measures the precise molecular weight of the compound in a sample and compares it against the expected mass of the target sequence.  Because peptide sequences can differ from one another by […]

Measuring Compound Purity With HPLC Testing

In addition to identity confirmation, every batch of research peptides is analyzed by high performance liquid chromatography (HPLC) to determine its purity. This method separates the target compound from residual synthesis byproducts based on subtle differences in chemical behavior, then measures the proportion of the sample that consists of the target peptide.  Research grade compounds […]
