Introduction: The Rise of Peptide Science
Peptides and longevity compounds are rapidly becoming one of the most talked-about categories in biohacking, regenerative medicine, and performance optimisation. From GLP-1 receptor agonists to cellular repair peptides, these molecules are at the forefront of a new era in human health. At SONOCOUTURE, we offer a curated range of research-grade freeze-dried peptides and compounds — each with a unique mechanism of action and a growing body of scientific literature behind it.
In this guide, we break down each compound in our Metabo GLP-3 Peptide collection, explaining what it is, how it works, and why researchers and biohackers are paying close attention.
GLP-1 & Metabolic Peptides
Semaglutide
Semaglutide is a GLP-1 receptor agonist originally developed for type 2 diabetes management. It mimics the hormone glucagon-like peptide-1, which regulates insulin secretion, slows gastric emptying, and reduces appetite. Research has shown significant effects on body weight reduction, cardiovascular risk markers, and metabolic health. It has become one of the most studied peptides in modern metabolic science.
Tirzepatide
Tirzepatide is a dual GIP and GLP-1 receptor agonist — a next-generation metabolic peptide that activates two incretin hormone pathways simultaneously. Clinical trials have demonstrated superior weight loss outcomes compared to single-receptor agonists, along with improvements in blood glucose control and lipid profiles. It represents a significant advancement in metabolic peptide research.
RETA (Retatrutide)
RETA, or Retatrutide, is a triple agonist targeting GLP-1, GIP, and glucagon receptors. As a triple incretin mimetic, it is being studied for its potential in obesity, metabolic syndrome, and non-alcoholic fatty liver disease (NAFLD). Early research suggests it may offer even greater metabolic benefits than dual agonists.
Tissue Repair & Recovery Peptides
BPC-157 (Body Protection Compound)
BPC-157 is a pentadecapeptide derived from a protein found in human gastric juice. It has been extensively studied for its regenerative properties, including tendon and ligament healing, gut mucosal repair, and neuroprotection. Research suggests it promotes angiogenesis (new blood vessel formation) and upregulates growth hormone receptors in tendon fibroblasts, making it a popular subject in sports medicine and wound healing research.
TB-500 (Thymosin Beta-4)
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide found in virtually all human and animal cells. It plays a key role in actin regulation, cell migration, and tissue repair. Research has highlighted its potential in accelerating wound healing, reducing inflammation, and promoting muscle repair — particularly relevant in the context of injury recovery and regenerative medicine.
CJC-1295
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH). It stimulates the pituitary gland to release growth hormone in a sustained manner. Research has explored its role in increasing lean muscle mass, reducing body fat, improving sleep quality, and supporting recovery. It is often studied in the context of anti-aging and performance research.
Tesamorelin 5mg
Tesamorelin is a stabilised analogue of GHRH that has been studied for its ability to reduce visceral adipose tissue (VAT) — the metabolically active fat stored around internal organs. It is one of the few peptides with significant clinical trial data supporting its effects on body composition, particularly in the context of metabolic and hormonal health research.
Cellular Health & Longevity Compounds
NAD+ (Nicotinamide Adenine Dinucleotide)
NAD+ is a coenzyme found in every living cell and is essential for energy metabolism, DNA repair, and cellular signalling. Levels of NAD+ decline significantly with age, and research into NAD+ supplementation has exploded in recent years. Studies suggest it may support mitochondrial function, activate sirtuins (longevity proteins), and improve cellular resilience — making it a cornerstone of longevity science.
GHK-Cu (Copper Peptide)
GHK-Cu is a naturally occurring copper peptide with a remarkable range of biological activities. Research has shown it can stimulate collagen and elastin synthesis, promote wound healing, activate antioxidant enzymes, and even modulate gene expression related to inflammation and tissue remodelling. It is widely studied in dermatology, wound care, and anti-aging research.
Most-C
Most-C is a cutting-edge peptide compound being explored for its role in cellular signalling and metabolic regulation. As research in this area continues to evolve, it represents the frontier of peptide science — with potential applications in longevity, metabolic health, and cellular optimisation.
Skin, Pigmentation & Aesthetic Peptides
Melanotan II
Melanotan II is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH). It acts on melanocortin receptors and has been studied for its effects on skin pigmentation, libido, and appetite suppression. Research has also explored its potential role in photoprotection — the idea that increased melanin production may offer some protection against UV-induced skin damage.
Snap-8 (Acetyl Octapeptide-3)
Snap-8 is an octapeptide that works by inhibiting the SNARE complex — the same mechanism targeted by botulinum toxin, but through a topical, non-invasive pathway. Research suggests it can reduce the depth of expression lines and wrinkles by limiting muscle contraction at the neuromuscular junction. It is a popular subject in cosmetic peptide research and anti-aging skincare science.
Immune & Anti-Inflammatory Peptides
KPV 10mg
KPV is a tripeptide (Lys-Pro-Val) derived from the C-terminal sequence of alpha-MSH. It has been studied for its potent anti-inflammatory properties, particularly in the context of gut inflammation, skin conditions, and immune modulation. Research suggests KPV can inhibit pro-inflammatory cytokines and may have applications in inflammatory bowel disease and wound healing.
Glutathione 600mg
Glutathione is the body's master antioxidant — a tripeptide composed of glutamine, cysteine, and glycine. It plays a central role in neutralising free radicals, supporting immune function, and detoxifying the liver. Research into glutathione supplementation has explored its role in skin brightening, heavy metal detoxification, and cellular protection against oxidative stress. At 600mg, this is a research-grade dose aligned with clinical study protocols.
Why Freeze-Dried Peptides?
All compounds in our Metabo GLP-3 Peptide range are available in freeze-dried (lyophilised) powder form. Lyophilisation preserves the structural integrity and bioactivity of peptides far more effectively than liquid formulations, ensuring maximum stability and shelf life. This is the gold standard format used in research settings worldwide.
