Best Peptides for Anxiety in 2026: Selank, Semax, and What Your COMT Gene Actually Predicts
Which peptides work best for anxiety? Selank and Semax target the same problem with opposite tools. Your COMT gene determines which one helps and which backfires.
Best Peptides for Sleep: DSIP vs Epithalon vs Ipamorelin (Which One Matches Your Biology)
Which peptides work best for sleep in 2026? DSIP, Epithalon, and ipamorelin each target different sleep problems. Your PER3 gene predicts which one you actually need.
AOD-9604 Fat Loss: What Six Human Trials Actually Showed
AOD-9604 ran more human trials than most research peptides and still failed its pivotal test. Here is what the data shows and whether your genes predict your response.
MOTS-c: The Mitochondrial Peptide Your Cells Lose With Age
Your mitochondria produce MOTS-c as a metabolic hormone. Levels fall with age and collapse in diabetes. One K14Q genetic variant changes your entire response profile.
Epithalon and Telomere Length: What the Research Shows
Epithalon broke the Hayflick limit in cultured human cells and cut cardiovascular mortality by 50% across a 12-year trial. Here is what 30 years of Russian data actually shows.
Selank for Anxiety: What 40% of Patients Felt in 3 Days
Selank matched medazepam in trials: 40% of patients hit sub-clinical anxiety in 3 days, with no withdrawal. Your BDNF and GABRA2 genes predict if you are a fast responder.
GHK-Cu Benefits: What the Science Says About the Copper Peptide Everyone's Talking About
GHK-Cu searches have surged over 500% in the past year. Here's what this copper peptide actually does, what it doesn't, and why your genetics determine whether it's worth trying.
Best Peptides for Weight Loss: A DNA-Guided Ranking (2026)
Semaglutide dominates the headlines, but it's not the only peptide that moves the scale. Here are the top 5 peptides for weight loss — ranked by evidence — and why your GLP1R and PPARG gene variants determine which one actually works for you.
Best Peptides for Skin: Anti-Aging, Collagen & What Your DNA Says (2026)
GHK-Cu, BPC-157, collagen peptides, Epithalon, Matrixyl — the skincare peptide market is exploding. Here's what actually works, what's marketing, and why your COL1A1 and SOD2 genes determine which peptide delivers results for your skin.
Best Peptides for Healing & Recovery: Ranked by Evidence (2026)
BPC-157, TB-500, GHK-Cu, KPV, Thymosin Alpha-1 — healing peptides cover everything from torn tendons to gut lining repair. Here's what the evidence actually supports, and how your NOS3, MMP3, and COL1A1 gene variants predict which one works best for your biology.
How BPC-157 Works in the Body: The Complete Mechanism Guide
BPC-157 is the most-researched healing peptide in the biohacking world. Here's exactly how it works — from nitric oxide signaling to tendon repair — and why your genetics determine how well it works for you.
How GHK-Cu Works: The Copper Peptide That Resets Your Skin's Gene Expression
GHK-Cu is the most scientifically validated anti-aging peptide in existence — 50 years of research, 4,048 genes modulated, and a direct SIRT1 binding mechanism discovered in 2025. Here's how it works and why your TGFB1 and COL1A1 variants determine your response.
