Aggregation-induced assay artefacts
Distinguish a response associated with molecular assemblies from evidence of a specific peptide–target interaction.
Read the article →Fluorescence interference from peptide reagents
Read fluorescent peptide measurements without assuming that a brighter signal always means more peptide or a larger biological response.
Read the article →Time-course measurements versus a single endpoint
Distinguish response size at one moment from onset, duration and recovery across an assay’s observation period.
Read the article →Orthogonal assays for a proposed peptide mechanism
Assess whether several experiments provide independent support for a peptide mechanism or repeat the same unresolved assumption.
Read the article →Concentration-response curves and non-monotonic patterns
Interpret rising, falling and turning assay responses without forcing every dataset into a single sigmoid or inferring an optimal human dose.
Read the article →BPC-157: identity and the published research landscape
A bounded guide to BPC-157 identity, selected tendon studies and a small human pilot, with clear limits on what each can establish.
Read the article →TB-500: naming ambiguity and the published literature
Separate full-length thymosin beta-4, its unmodified fragment and acetylated TB-500 when deciding which research applies to a named material.
Read the article →Semax: molecular identity and research context
Identify Semax and distinguish selected rat brain studies from a small human performance study without turning either into a general cognitive claim.
Read the article →Selank: molecular identity and research context
A precise introduction to Selank, with a rat neurotransmission study and a human comparative report kept within their actual evidence boundaries.
Read the article →GHK-Cu: complex identity and research context
Separate the GHK peptide from its copper complex and read selected chemistry and fibroblast papers without turning them into product efficacy claims.
Read the article →Retatrutide: molecular identity and the research record
Identify retatrutide as LY3437943 and distinguish discovery studies, published clinical trials and newer sponsor announcements from claims about research vials.
