Key Takeaways: “While both SARMs and peptides are used in performance and therapeutic research, they are chemically and mechanistically distinct. SARMs are non-peptidic, small-molecule ligands designed to selectively modulate androgen receptors, whereas peptides are amino acid chains that typically act through hormonal signalling pathways. Conflating the two reflects a misunderstanding of fundamental molecular biology.”– Dr. …

Glossary: Peptide – What It Is & Why It Matters in Research and Fitness
Definition: A peptide is a short chain of amino acids linked by peptide bonds. In the body, peptides act as signalling molecules, controlling everything from hormone release to tissue repair. They’re smaller than proteins and are either naturally produced or synthetically engineered for therapeutic or research use. Quick Summary Term Peptide Type Short amino acid …

Is MK-677 a Steroid or a SARM? Here’s What Science (and Experts) Say
Key Takeaways The Confusion Around MK‑677: Why So Many People Get It Wrong If you’ve browsed fitness forums or supplement sites, you’ve probably seen MK‑677 (Ibutamoren) grouped with SARMs – or even called a “non‑steroidal steroid.” But here’s the truth: MK‑677 is not a SARM, not a steroid, and not a peptide. So why the …

Can Enclomiphene Cause Erectile Dysfunction?
Short answer:No – enclomiphene is unlikely to cause erectile dysfunction (ED).In most cases, it does the opposite. But let’s unpack why people ask this, what the science actually shows, and when problems canhappen. “It is generally accepted that nitric oxide (NO) is the principal agent responsible for relaxation of penile smooth muscle.” PMC The Core …

Glossary: Tissue Selectivity
What Is Tissue Selectivity? (Simple Definition) Tissue selectivity is the ability of a drug or compound to activate receptors in some tissues while avoiding others.With SARMs, this means switching on muscle- and bone-building signals without strongly activating androgenic pathways in the prostate, skin, or hair follicles. It’s the core scientific reason SARMs exist. Why Tissue …

Can SARMs Cause Infertility? What the Science Really Shows
Short answer: Yes – SARMs can cause temporary infertility, and in some cases, prolonged suppression. While they’re often marketed as “safer than steroids,” the endocrine disruption risk is very real. Note: All information provided is in reference to authorised trials and theoretical data. This not health advice. SARMs are not authorised for use outside of …
