Most HGH peptide compounds — including HGH Fragment 176–191, MOD-GRF 1–29, IGF-1 LR3, IGF-1 DES 1–3, and MGF — are not classified as controlled substances under current UK law. They may be legally purchased and possessed for legitimate laboratory research purposes. Full-sequence recombinant HGH (somatropin) is a Class C controlled substance and Prescription Only Medicine, and is illegal to supply without a valid prescription. See our full UK legal guide.

Yes. Full-sequence recombinant HGH (somatropin) is listed in Schedule 4 Part II of the Misuse of Drugs Act 1971 as a Class C controlled substance, and is also a Prescription Only Medicine under the Human Medicines Regulations 2012. Possessing somatropin without a prescription or supplying it without authorisation is a criminal offence in the UK.

Our products are available to qualified researchers, scientists, and professionals who intend to use them for in-vitro laboratory research only. By purchasing, customers confirm they are acting in compliance with all applicable UK laws and that products will not be used for human or veterinary consumption, self-administration, or clinical application.

Yes. HGH Peptides UK Ltd is a company registered in England and Wales. Our company registration number is listed in the website footer and on our About page. We operate in compliance with MHRA guidelines for the supply of research compounds and UK e-commerce regulations.

No. All products are sold strictly for in-vitro laboratory research and scientific study. They are not approved, tested, or intended for human or veterinary consumption, self-administration, or clinical use. They are not medicines or supplements. Purchasing for personal use or self-administration is a misuse of these products and may constitute a legal offence depending on the compound.

Every batch is independently HPLC-verified to ≥99% purity before being listed for sale. We hold certificates of analysis for every batch of every product. We do not list any compound that has not passed independent third-party testing. Certificates are available on request for any product.

Yes. Batch-level certificates of analysis are available for every product on request. Email us at [email protected] with your order number and the specific product(s) you need documentation for. We will supply the relevant CoA documents within one business day.

Lyophilised (freeze-dried) peptide vials should be stored at -20°C unopened. Once reconstituted with bacteriostatic water, store at 2–8°C and use within 4 weeks. Avoid prolonged exposure to light, heat, or repeated freeze-thaw cycles. Bacteriostatic water is not included with peptide vials and should be ordered separately if required.

Full HGH (somatropin) is the complete 191-amino acid growth hormone molecule. HGH peptides are shorter sequences that either stimulate the pituitary to release its own GH (secretagogues like MOD-GRF), or target a specific function of the HGH molecule (fragments like Fragment 176–191). Peptides are typically not classified as controlled substances, unlike somatropin. See our HGH vs Peptides guide.

We stock injectable HGH from: Syncom Labs (Syntropin, rDNA Syntropin), Evotech (Evotropin), Beligas Pharmaceuticals (Beltropin), Deus Medical (Deustropin), SOMA-TEX, Pharmaqo Labs (Qomatropin), and Adelphi Research (Tropin). All brands are independently HPLC-tested to ≥99% purity before listing. See the full injectable HGH category.

Our products are research-grade, not pharmaceutical-grade (pharmaceutical grade implies regulatory approval for clinical use, which none of these products have). Research-grade means independently verified purity to ≥99% by HPLC, suitable for laboratory research applications. This is the standard used across the research compound industry.

Our HGH injection prices range from £25 (Fragment 176–191 5mg) to £270 (rDNA Syntropin 100iu). Full 100–120iu injectable somatropin kits cost between £160 and £270 depending on brand. Peptide fragments start from £25. All prices are in GBP with no hidden fees. Free shipping on orders over £75. See our full HGH price guide.

We accept Visa, Mastercard, American Express, PayPal, and cryptocurrency (Bitcoin and other major coins). All card payments are processed via an SSL-encrypted checkout. Cryptocurrency payments offer additional privacy and are processed at the checkout conversion rate on the day of payment.

No. All prices are displayed in GBP inclusive of VAT where applicable. The only additional charge is shipping on orders under £75. There are no transaction fees, conversion charges, or surprise costs. What you see on the product page is what you pay at checkout.

Yes. Volume discounts are available for qualifying research institutions and repeat purchasers. Contact us at [email protected] with details of the products and quantities you require and we will provide a tailored quote.

Due to the nature of research compounds, we are unable to accept returns of opened or used products. If you receive a damaged, incorrect, or defective order, contact us within 48 hours of delivery with photos and your order number. We will arrange a replacement or refund as appropriate at no cost to you.

HGH Fragment 176–191 is the C-terminal fragment of the human growth hormone molecule (amino acids 176–191). Research has focused on its lipolytic (fat-breakdown) activity in adipose tissue models. It activates beta-3 adrenergic receptors and inhibits lipogenesis without the blood glucose-raising effects of full-length HGH, making it useful for research specifically targeting fat metabolism pathways.

MOD-GRF 1–29 (also called CJC-1295 without DAC) is a GHRH analogue with a short active window (~30 minutes), producing pulsatile GH release via the pituitary. CJC-1295 with DAC attaches to plasma albumin, extending half-life to ~8 days and producing continuous GH elevation. MOD-GRF preserves the physiological pulsatile GH pattern; CJC-1295 with DAC produces a continuous bleed. Most research protocols prefer MOD-GRF for its more physiological profile.

IGF-1 LR3 has an extended half-life (~20–30 hours) due to reduced IGFBP binding, making it suitable for systemic or sustained-exposure research protocols. IGF-1 DES 1–3 is a truncated variant lacking the first three N-terminal amino acids, resulting in approximately 3x higher IGF-1 receptor binding affinity. DES is preferred for local tissue studies requiring higher potency; LR3 for longer-duration systemic investigations.

Multi-compound research protocols are common in published GH axis research. MOD-GRF 1–29 is frequently combined with a GHRP compound (GHRP-2, GHRP-6, or Ipamorelin) to achieve synergistic GH output through complementary receptor mechanisms (GHRH-R + GHS-R1a). IGF-1 compounds are sometimes used in combination with anabolic signalling research. Always review published literature for your specific research question before designing a multi-compound protocol.

MGF is a splice variant of IGF-1 produced locally in muscle tissue in response to mechanical loading or damage. Its E-peptide domain is distinct from other IGF-1 isoforms and has been shown to activate muscle satellite cells (myogenic stem cells) in research models. It is used in research investigating muscle repair, satellite cell activation, and local IGF-1 signalling, independently of systemic GH/IGF-1 axis activity.
