Quick links: Why This Matters MK-677 has sparked widespread interest in scientific and performance research for its role in stimulating growth hormone (GH) and insulin-like growth factor 1 (IGF-1). But let’s set the record straight: MK-677 is not approved for human use anywhere in the UK, EU, or US. Its use is strictly limited to …

Are SARMs Peptides? Here’s the Clear Science-Based Answer
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. …
MoreIs 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 …
MoreHow to Verify SARMs Quality in 10 Steps (A Researcher’s Checklist)
Are the SARMs you’re using really what they claim to be? In an industry flooded with underdosed, mislabeled, or outright fake compounds, knowing how to verify SARMs quality is critical – especially for researchers who rely on consistency, purity, and safety. Here’s your step-by-step checklist to ensure you’re working with legitimate, research-grade SARMs. Key Takeaways …
MoreWhat Is RAD-140? Updated Guidance for Researchers
If you’ve ever searched for SARMs, one name shows up everywhere: RAD-140, often called Testolone.But what is RAD-140, really?And why has it become one of the most talked-about research compounds of the last decade? Key Takeaways Let’s break it down using the latest data, a clear explanation of mechanisms, and what researchers should actually know …
MoreHow Long Do SARMs Stay In Your System? What the New Research Says (Case Study)
Key Takeaways You’ve probably seen this question asked everywhere – Reddit threads, research forums, even gym locker rooms: Whether you’re designing a compliant research protocol, preparing for bloodwork, or just trying to understand metabolic timelines, the answer is more complex than you might think. Let’s break it down by compound, half-life, detection methods, and the …
MoreCan 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 …
MoreCan 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 …
MoreDoes RAD140 Increase or Decrease Testosterone?
Evidence from Human Clinical Trials TL;DR:Clinical trial data shows that RAD140 decreases natural testosterone levels through suppression of the hypothalamic-pituitary-gonadal (HPG) axis. Despite its anabolic properties, it does not raise testosterone, and suppression has been observed even at therapeutic doses. Key Takeaways: Does RAD140 Increase or Decrease Testosterone? What Clinical Trials Say About RAD140 and …
