Peptide Angio-3 Attenuates Pulmonary Fibrosis Via Modulation of Coagulation Factor Xa-PAR-1 Signaling Axis
Angio-3, a 10-residue peptide derived from human plasminogen kringle 3, demonstrated significant antifibrotic activity in pulmonary fibrosis models by functioning as a PAR-1 antagonist that disrupts the coagulation factor Xa-PAR-1 signaling axis. The peptide inhibited fibroblast invasion and migration with a favorable safety profile—no adverse effects at 0.5 mg/kg/day and only mild hepatomegaly at supratherapeutic doses.
GHK-Cu vs Retinol vs Vitamin C for Skin Rejuvenation: Which Actually Works Best?
GHK-Cu vs retinol vs vitamin C compared for skin rejuvenation — efficacy data, mechanisms, side effects, and who should use what.
Large-Scale GWAS Identifies Genetic Predictors of GLP-1 Weight Loss Efficacy and Side Effects
A genome-wide association study of GLP-1 receptor agonist users published in Nature identifies genetic variants that predict weight loss response and side effects, laying groundwork for precision prescribing of semaglutide and tirzepatide.
Retatrutide Achieves 2.0% A1C Reduction and 16.8% Weight Loss in Phase 3 TRANSCEND-T2D-1 Trial
Eli Lilly's triple GIP/GLP-1/glucagon receptor agonist retatrutide met all primary and key secondary endpoints in its first Phase 3 diabetes trial, delivering superior A1C reduction and substantial weight loss over 40 weeks.
Early Tirzepatide and Semaglutide Intervention Shows Comparable Anti-Atherosclerotic Effects in Preclinical Models
A 2026 study in Nature Scientific Reports demonstrates that early intervention with tirzepatide produces anti-atherosclerotic effects comparable to semaglutide, supporting the concept that dual GIP/GLP-1 signaling confers vascular protection beyond glycemic control.

Game-changer for my knee recovery
After 6 weeks of subcutaneous injections, the chronic tendon pain I'd had for 2 years was down to almost nothing. Combined with PT, the results were remarkable.

Steady weight loss, minimal sides
Lost 14 lbs over 3 months on the titration schedule. Nausea was real the first 2 weeks but manageable. Worth it for the appetite control alone.

Best GH stack I've tried
Noticeably better sleep by week 2, improved recovery from training by week 4. Skin quality improved. No water retention like with GHRP-6.
