CJC-1295 and GHRH: sustained exposure versus pulsatile secretion
Separate persistence of a releasing-hormone stimulus from the timing, trough level and total output of growth hormone.
Read the article →Semax and its fragments: following the measured molecule
Distinguish intact Semax from shorter products in degradation studies and avoid treating a labelled signal as proof of intact peptide.
Read the article →Selank and tuftsin: what a sequence extension does not prove
Compare Selank with its shorter structural relative using direct animal experiments, while keeping the measured outcomes and evidence gaps explicit.
Read the article →Thymosin Alpha 1 and Thymosin Beta 4: unrelated naming assumptions
Use precursor and gene records to separate two thymosin identities before carrying a molecular finding between them.
Read the article →NAD+ and NADH: oxidised and reduced forms
Distinguish redox identity from protonation state and understand why a total NAD measurement cannot determine a redox ratio.
Read the article →GLOW and KLOW: comparing declared blend compositions
Compare the supplied GLOW and KLOW compositions on a component basis, keeping total mass, component fractions and evidence for the mixture separate.
Read the article →How to read a peptide certificate of analysis
A practical guide to checking a peptide COA: match the sample, separate identity from purity and content, and read each result against its stated limit.
Read the article →Matching a certificate to a vial and lot
A step-by-step way to connect a product, vial size, lot and laboratory report—and resolve a mismatch before relying on the results.
Read the article →Analysis dates, issue dates and expiry dates on certificates
How to distinguish receipt, testing, preparation, approval, retest and expiry dates without inventing a shelf life from a certificate.
Read the article →Reported result, specification and acceptance limit
Read a certificate row correctly: identify the measured attribute, its units, the applicable limit and the laboratory's decision rule.
Read the article →What does not detected mean on a certificate?
Understand ND, detection limits, quantitation limits and less-than results—and why none should be casually rewritten as zero.
