The compound moved from a promising signal to a late-stage asset with data across obesity, diabetes, and CVD.Research TB-500 and Thymosin Beta-4: Why the Fragment Isn't the Moleculehttps://biohackhealth.uk/blog/tb-500-thymosin-beta-4/https://biohackhealth.uk/blog/tb-500-thymosin-beta-4/Mon, 24 Aug 2026 23:00:00 GMTMost writing about TB-500 cites research about Thymosin Beta-4. Those are not the same thing, and the gap between them is the most important fact about this compound.Research Peptide Regulation in 2026: What Actually Changedhttps://biohackhealth.uk/blog/peptide-regulation-2026/https://biohackhealth.uk/blog/peptide-regulation-2026/Mon, 24 Aug 2026 23:00:00 GMTThe regulatory landscape shifted through three separate mechanisms: a compounding decision in 2023, shortage resolutions in 2024-25, and an enforcement campaign in 2026.News Collagen Peptides: The One With Actual Human Trialshttps://biohackhealth.uk/blog/collagen-peptides-human-trials/https://biohackhealth.uk/blog/collagen-peptides-human-trials/Mon, 24 Aug 2026 23:00:00 GMTUnusually for this space, the core findings come from controlled trials in people. Effect sizes are modest, and the protocol matters more than the product.Research GLP-1 Agonists and the Metabolic Flexibility Questionhttps://biohackhealth.uk/blog/glp1-metabolic-flexibility/https://biohackhealth.uk/blog/glp1-metabolic-flexibility/Mon, 24 Aug 2026 23:00:00 GMTThe open question isn't whether these drugs work—it's what they leave behind. Do they improve underlying flexibility or just reduce the load on a broken system?Research BPC-157: A Deep Preclinical File and an Empty Clinical Onehttps://biohackhealth.uk/blog/bpc-157-preclinical-file/https://biohackhealth.uk/blog/bpc-157-preclinical-file/Mon, 24 Aug 2026 23:00:00 GMTNo completed modern controlled human trial exists. Everything describing efficacy comes from animal models or cell culture. Both of these facts are true at once.Research
