BPC-157 is one of the most studied healing peptides in research. This complete guide covers its mechanisms, benefits for gut healing, tendon repair and neuroprotection, dosing protocols.
GLP-1
On April 1, 2026, the FDA approved Foundayo (orforglipron) — and the GLP-1 landscape changed overnight. For the first time, patients can take an oral GLP-1 receptor agonist without any food or water restrictions. No 30-minute fasting window. No injection. Just a daily pill, taken whenever is convenient. But what exactly
Peptides
If you've spent time in longevity circles, you've almost certainly encountered the name Epithalon. Marketed as an anti-aging breakthrough, this synthetic tetrapeptide has drawn both serious scientific interest and a passionate community of biohackers looking to slow the clock. But what does the research actually say?
Peptides
If you've spent any time in the world of peptides, you've almost certainly encountered TB-500 — often discussed alongside BPC-157 as one half of the so-called "wolverine stack." But TB-500 is more than a supporting player. It's a synthetic analog of Thymosin Beta-4,

GLP-1
Retatrutide targets three hormones — GLP-1, GIP, and glucagon — and has achieved 28.7% body weight loss in Phase 3 trials, rivaling bariatric surgery. Here's what you need to know.
GLP-1
For a moment in 2023 and 2024, Pfizer's danuglipron looked like it might democratize the GLP-1 revolution. An oral pill — no injections, no refrigeration, no weekly shot schedules — that could help millions lose significant weight. Then, in April 2025, Pfizer pulled the plug. One patient. One liver injury
Peptides
Semax is one of the most studied cognitive-enhancing peptides in existence — yet outside of Russia, most people have never heard of it. Originally developed at the Institute of Molecular Genetics of the Russian Academy of Sciences in the 1980s, Semax has been a registered pharmaceutical in Russia for decades, prescribed
Peptides
Kisspeptin is the master switch of the human reproductive system. A single peptide that sits at the very top of the hormonal cascade — controlling testosterone, fertility, libido, and more — yet remains largely unknown outside specialist clinics and biohacker communities. That's changing fast. With multiple Phase 2 clinical trials
Peptides
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that has captured significant interest among researchers, athletes, and longevity-focused individuals. As one of the earliest and most studied growth hormone secretagogues, GHRP-6 offers a unique profile that extends well beyond simple GH stimulation — including striking cytoprotective, cardioprotective, and wound-healing properties
PT-141, the research name for the compound now marketed as Vyleesi (bremelanotide), occupies a unique position in the world of sexual health medicine. It's the only FDA-approved drug for low sexual desire in women that works through the brain rather than the body — and it's the
Tirzepatide has redefined what's possible in metabolic medicine. Marketed as Mounjaro for type 2 diabetes and Zepbound for obesity, this once-weekly injectable has produced weight loss results that no drug in history has matched in a phase 3 trial. If you're trying to understand what tirzepatide
