Your guide to peptides in 2026
GHK-Cu — The Copper Peptide That Touches Everything GHK-Cu Some compounds in the research peptide world do one thing exceptionally well. GHK-Cu does many things and does most of them with an evidence base that is, by the standards of this library, genuinely remarkable. GHK — glycyl-L-histidyl-L-lysine — is a tripeptide that occurs naturally in…
Selank and N-Acetyl Selank — The Anxiolytic That Leaves Your Mind Intact Anxiety is one of the most cognitively expensive experiences the brain can have. The rumination, the hypervigilance, the constant low-level threat assessment — all of it consumes the prefrontal cortex’s limited processing capacity, leaving less available for the thinking, learning and creative work…
CJC-1295 with Ipamorelin — The Growth Hormone Stack That Works Better Together There is an elegant piece of biology at the heart of why CJC-1295 and Ipamorelin are almost always used together rather than alone. The pituitary gland — the small structure at the base of the brain responsible for releasing growth hormone — has…
BPC-157 — The Body Protection Compound That Heals From the Inside Out BPC-157 In 1993 a Croatian research team were studying something that had puzzled scientists for years — why the human stomach can heal extreme acid damage that would destroy almost any other tissue in the body. The stomach lining faces conditions that would…
TB-500 and Thymosin Beta-4 — The Complete Systemic Recovery Guide TB-500 and Thymosin Beta-4 If you have researched recovery peptides for any length of time you will have encountered both of these names — sometimes used interchangeably, sometimes as if they are completely separate compounds. The confusion is understandable but the distinction matters, and getting…
MGF and PEG-MGF — The Muscle Repair Signal and Its Longer Lasting Partner MGF and PEG-MGF Every time you train hard enough to create meaningful muscle stress, your body launches a repair response within minutes. Before the soreness arrives, before the inflammation peaks, before the satellite cells that will rebuild the damaged tissue begin to…
Cerebrolysin — The Neuropeptide Mixture With 50 Years of Clinical History Behind It Cerebrolysin — The Neuropeptide Mixture With 50 Years of Clinical History Behind It Every compound in the Brain and Mood section of this library works through a mechanism that is, to varying degrees, still being characterised. Semax has decades of Russian clinical…
DSIP — The Peptide That Works With Your Sleep Architecture Rather Than Overriding It There is a meaningful difference between compounds that make you unconscious and compounds that make you sleep better. Most conventional sleep aids — benzodiazepines, Z-drugs, antihistamines — belong in the first category. They work by sedating the central nervous system, forcing…
Semaglutide — The Most Extensively Studied Weight Loss Peptide Available Semaglutide There are very few compounds in the history of metabolic medicine that have changed the conversation as completely as semaglutide. In clinical settings, the results it produces have surprised even the researchers running the trials. In the broader public, it has become one of…
Tirzepatide — The Dual Action Weight Loss Peptide That Outperformed Semaglutide Tirzepatide For years, semaglutide held the position as the most effective pharmacological weight loss compound available. Then tirzepatide arrived — and the clinical trials changed the conversation again. In the first ever direct head-to-head comparison of the two compounds, published in the New England…
