Research
Stability, salt forms, bioavailability, certificates of analysis and what cGMP requires. The parts of the category that are engineering rather than marketing.
Heat, light, oxygen, pH and freeze-thaw all degrade peptides through specific chemical routes. Here is what actually happens to the molecule.
Read article →Skin is an excellent barrier, and peptides are exactly the kind of molecule it is built to exclude. What patch technology can realistically achieve.
Read article →Counter-ion selection changes solubility, hygroscopicity and stability without changing the active molecule. What the arginate salt is for.
Read article →A COA is a real document with real limits. How to read one, and which absences should bother you.
Read article →The phrase appears on almost every label. Here is the substance behind it, and why dietary supplement cGMP is a different standard from drug cGMP.
Read article →Why oral peptide bioavailability is usually reported in fractions of a percent, and what that implies for dosing claims.
Read article →Rice powder, magnesium stearate, silicon dioxide, hypromellose. What each is doing, and why removing them is not an upgrade.
Read article →Where the molecule in the bottle comes from, why longer sequences cost more, and what impurities the process leaves behind.
Read article →A 99 percent pure peptide can still deliver far less active than the label claims. The two figures answer different questions.
Read article →An old compound with genuine pharmacology, a strongly dose-dependent effect, and one interaction that is not negotiable.
