This guide explains how it compares with GHK-Cu and why safety matters. 23 Aug 2026 Read [AHK-Cu Peptide Guide: Skin, Hair and Research Use](https://peptidesupermarket.co.uk/research/ahk-cu-peptide-guide-skin-hair-and-research-use) Guides 6 min HMG ### HMG fertility guide: FSH, LH and how menotropins are discussed in research HMG, or human menopausal gonadotropin, is discussed in fertility research because it provides both FSH and LH activity. This guide explains the mechanism, comparisons and key cautions. 23 Aug 2026 Read [HMG fertility guide: FSH, LH and how menotropins are discussed in research](https://peptidesupermarket.co.uk/research/hmg-fertility-guide-fsh-lh-and-how-menotropins-are-discussed-in-research) Guides 11 min GHRP 2 ### GHRP-2 guide: mechanism, research uses and safety considerations A research-focused guide to GHRP-2, also called growth hormone releasing peptide 2, covering its ghrelin receptor mechanism, study findings, comparisons and safety signals. 23 Aug 2026 Read [GHRP-2 guide: mechanism, research uses and safety considerations](https://peptidesupermarket.co.uk/research/ghrp-2-guide-mechanism-research-uses-and-safety-considerations) Guides 9 min ARA-290 ### ARA290: how this EPO-derived peptide sends a repair signal without raising red blood cells ARA290, also known as cibinetide, is studied for tissue protection, inflammation signalling and small fibre neuropathy models. Its appeal is its separation from EPO's red blood cell effects. 23 Aug 2026 Read [ARA290: how this EPO-derived peptide sends a repair signal without raising red blood cells](https://peptidesupermarket.co.uk/research/ara290-how-this-epo-derived-peptide-sends-a-repair-signal-without-raising-red-blood-cells) Guides 7 min Adipotide ### Adipotide Guide: Research Mechanism, Uses and Safety A research-focused guide to Adipotide, covering its proposed fat-targeting mechanism, monitoring considerations, limitations and UK sourcing checks. 23 Aug 2026 Read [Adipotide Guide: Research Mechanism, Uses and Safety](https://peptidesupermarket.co.uk/research/adipotide-guide-research-mechanism-uses-and-safety) Guides 7 min Humanin ### Humanin peptide: what mitochondrial stress signalling research shows Humanin is a small mitochondrial-derived peptide studied for cell survival, stress signalling and metabolism. The strongest evidence remains preclinical, with human trials still limited. 23 Aug 2026 Read [Humanin peptide: what mitochondrial stress signalling research shows](https://peptidesupermarket.co.uk/research/humanin-peptide-what-mitochondrial-stress-signalling-research-shows) Guides 8 min IGF-1 Long R3 ### IGF-1 LR3 benefits: a research guide to mechanisms and risks IGF-1 LR3 is usually discussed for muscle signalling, but the research conversation also covers metabolism, cognition, bone health and safety questions. 13 Aug 2026 Read [IGF-1 LR3 benefits: a research guide to mechanisms and risks](https://peptidesupermarket.co.uk/research/igf-1-lr3-benefits-a-research-guide-to-mechanisms-and-risks) Guides 4 min Glutathione ### Glutathione Explained: What It Does and Why It Matters Glutathione is often called the body’s master antioxidant, but that description only tells part of the story. Here is what it actually does and why the conversation around it is more nuanced than most people realise. 29 Jun 2026 Read [Glutathione Explained: What It Does and Why It Matters](https://peptidesupermarket.co.uk/research/glutathione-explained-what-it-does-and-why-it-matters) Guides 5 min Cagrilintide ### Cagrilintide Explained: The Amylin Signal Behind Fullness Cagrilintide is often described as a peptide that supports satiety through the amylin pathway. Here is why that matters and why it is not just another GLP-1 conversation. 29 Jun 2026 Read [Cagrilintide Explained: The Amylin Signal Behind Fullness](https://peptidesupermarket.co.uk/research/cagrilintide-explained-the-amylin-signal-behind-fullness) Guides 5 min Abaloparatide ### How Abaloparatide Works to Rebuild Bone Abaloparatide is often discussed as a bone-building treatment because it helps stimulate osteoblast activity and improve bone mineral density in key fracture-prone areas. 24 Apr 2026 Read [How Abaloparatide Works to Rebuild Bone](https://peptidesupermarket.co.uk/research/how-abaloparatide-works-to-rebuild-bone) Guides 5 min ACE-031 ### Follistatin-344 vs ACE-031: How These Myostatin Inhibitors Differ Follistatin-344 and ACE-031 are both discussed as myostatin inhibitors, but they do not work in the same way and they do not carry the same research story. 15 Apr 2026 Read [Follistatin-344 vs ACE-031: How These Myostatin Inhibitors Differ](https://peptidesupermarket.co.uk/research/follistatin-344-vs-ace-031-how-these-myostatin-inhibitors-differ) --- *Add `.md` to any page URL on peptidesupermarket.co.uk for its Markdown version.
