Textos prácticos sobre analítica de péptidos, control de calidad y manipulación: lo que determina si un ensayo es fiable.
Ipamorelin & CJC-1295 (DAC vs. No DAC): Pulsatile GH Release vs. Continuous Elevation in Preclinical Research
A technical analysis of Ipamorelin and CJC-1295 (DAC vs. No DAC). Compare GHS-R1a affinity, GHRH kinetics, pulsatile pituitary secretion, and reconstitution.
BPC-157 and TB-500: The Molecular Synergy of Angiogenesis and Actin Upregulation
A technical comparison of BPC-157 and TB-500 in tissue regeneration models. Explore angiogenic signaling, actin regulation, and reconstitution guidelines.
AnalyticsSemaglutide vs. Tirzepatide: Comparing Mono-GLP-1 and Dual GLP-1/GIP Agonism in Laboratory Models
A technical comparison of Semaglutide vs. Tirzepatide in research models. Explore receptor kinetics, structural biochemistry, and laboratory reconstitution data.
QualityHow to read a peptide certificate of analysis
Purity, identity, endotoxin, residual solvents — what each number on a peptide COA actually proves, and the four fields to check before you trust it.
AnalyticsHPLC purity vs mass spec identity: what each assay actually proves
Purity and identity are different questions with different answers. Why a peptide needs both, what each instrument measures, and why one number cannot substitute for the other.
QualityEndotoxin testing: the assay that decides whether a batch is usable
What a kinetic LAL endotoxin test measures, why lipopolysaccharide ruins cell-culture results, and how to read an EU/mg limit before you order.
HandlingStorage, reconstitution and cold chain: keeping peptides stable
Why lyophilized peptides are stored frozen, what actually degrades them, how to handle freeze–thaw cycles, and what to look for when a parcel arrives.
ReferenceThe five research categories, and what distinguishes them
Recovery, growth, metabolic, longevity and tanning — how the catalogue is organised, which receptor families each category maps to, and where the overlaps are.
BuyingChoosing a fill size: 5 mg, 10 mg or 20 mg
Why the same compound is sold in several vial sizes, what changes between them beyond the label, and how to pick the format that fits your work.
Por dónde empezar
Si estás aquí para comprar más que para leer, el catálogo completo enumera cada compuesto y cada formato, con su propio certificado de análisis. Si estás comprobando un compuesto concreto, el registro de lotes muestra los resultados del lote actual, y nuestro sistema de calidad explica qué significan esos resultados.
