Medical science explained clearly
Evidence-based insights into bioactive peptides, hormone replacement therapy, GLP-1 mechanisms, and healthy aging protocols.
The science behind compounded GLP-1 medications: a clinical guide
What a GLP-1 receptor agonist does, how semaglutide and tirzepatide differ, and what “compounded” actually means in the US. Including the clarification the FDA publishes about 503A pharmacies.

Copper and collagen: how much food provides, how much the body needs, and where the limit sits
Copper is a cofactor of the enzyme that cross-links collagen. How much you need daily, what a real measured plate provides, and why the usual problem is not a shortage.

GHK-Cu: what the copper peptide does in skin, and what the evidence does not support
A copper-bound tripeptide that skin releases when damaged. What has been measured in collagen and elastin, what has only been seen in cells and animals, and what cannot be promised.

Hormone optimization: what the guidelines say about TRT and hormone therapy
“Balancing hormones” is not a measurable outcome. What the Endocrine Society requires to diagnose hypogonadism, what TRAVERSE showed about the cardiovascular safety of testosterone, and what NAMS says about hormone therapy at menopause.

Injectable or oral: why most peptides are injected
Why the digestive tract destroys peptides, what had to be invented to get the first oral one approved, and what alternatives are still in trials.

Sermorelin and NAD+: what has actually been measured in cellular longevity
Circulating NAD+ rises with oral precursors, but the clinical benefit remains variable. And sermorelin: what it is, what the one paper arguing for its use in longevity actually says, and why no current presentation appears in the FDA's public databases.

Therapeutic peptides: how they mimic hormones your body already makes
What a therapeutic peptide is, how it relates to the insulin and GLP-1 your body already makes, and why nearly all of them are modified before prescription.

Why some peptides are given once a week
The natural hormone lasts minutes and the treatment lasts a week. These are the two techniques used to achieve that, and the problem each one created.

What GLP-1 is and how it works in your body
The hormone your gut produces to regulate glucose: where its receptors sit, what it does, why it lasts minutes, and why analogues exist.

What a therapeutic peptide can and cannot do
A peptide is a size class, not a promise. What it can do with specificity, what it cannot cross, and why two peptides can have opposite effects.
