The global pursuit of effective weight management solutions has entered a new, sophisticated era. Moving beyond traditional diet and exercise paradigms, the scientific community is now focused on targeted biochemical interventions. Among the most promising of these are peptide supplements for weight loss. Unlike broad-spectrum stimulants, peptides like 158861 67 7 (GHRP-2) offer a highly specific mechanism of action, tapping into the body's natural regulatory systems to optimize metabolism, promote fat loss, and encourage lean muscle development.
Recent market analysis indicates a compound annual growth rate (CAGR) of over 8.5% in the therapeutic peptide market, with metabolic and weight loss applications being a significant driver. This surge is fueled by a deeper understanding of the endocrine system and the role of growth hormone secretagogues. Researchers and institutions are increasingly choosing high-purity peptides to investigate novel peptide therapy for weight loss, aiming for results that are both effective and aligned with the body's intrinsic physiological pathways. The demand for reliable suppliers of research-grade peptides for weight loss for sale, such as Weimiao Bio, has never been higher, reflecting a clear industry trend towards precision and quality in metabolic research.
To ensure reproducible and reliable research outcomes, understanding the precise technical parameters of a peptide is paramount. Our Ghrp-2, identified by CAS number 158861 67 7, is synthesized and purified to meet the highest industry standards. Below is a comprehensive data sheet detailing its key characteristics.

This level of detail and transparency ensures that researchers using our peptides for fat loss and muscle gain can proceed with confidence, knowing the exact nature of the compound they are working with.
Our GHRP-2 is supplied as a lyophilized powder to ensure maximum stability and shelf-life.
The efficacy and safety of any weight loss peptide supplement are directly tied to its purity and the precision of its manufacturing process. At Weimiao Bio, we utilize state-of-the-art Solid-Phase Peptide Synthesis (SPPS) to produce our GHRP-2. This method, unlike less controlled liquid-phase synthesis, allows for superior purity, scalability, and batch-to-batch consistency. The entire process is conducted under strict laboratory conditions adhering to quality management principles akin to ISO 9001 standards.

In the expanding field of research chemicals for metabolic modulation, it's crucial to understand the distinct profiles of different compounds. GHRP-2, while a powerful growth hormone secretagogue, has unique characteristics when compared to other peptides like Ipamorelin or even SARMs like LGD-3303 (CAS 917891-35-1). The following chart visualizes the key performance indicators for researchers investigating peptides for belly fat and muscle gain.
Attribute: Growth Hormone Release Potency
This chart illustrates that while all compounds are studied for body composition changes, they operate differently. GHRP-2 provides one of the strongest GH pulses, making it a focal point for studies on peptide weight loss therapy. In contrast, Ipamorelin offers a more controlled release with fewer potential side effects like increased cortisol or prolactin, and LGD-3303 acts via androgen receptors, not the ghrelin receptor. Choosing the right compound depends entirely on the specific goals of the research project.
Each vial from Weimiao Bio is a testament to our commitment to quality in the field of peptide treatment for weight loss research.
GHRP-2 (158861 67 7) is a cornerstone compound for in-vitro and in-vivo studies exploring the ghrelin/growth hormone secretagogue receptor axis. Its primary application is in academic and private research labs investigating:
Client: A leading university's Endocrinology Department.
Objective: To assess the impact of GHRP-2 on visceral adipose tissue (VAT) reduction and lean mass preservation in a rodent model of diet-induced obesity.
Solution Provided by Weimiao Bio: We supplied three batches of 158861 67 7 with a guaranteed purity of >99.5%, complete with individual COAs and batch-to-batch consistency data. We also provided consultation on reconstitution and storage protocols to ensure the peptide's integrity throughout the long-term study.
Outcome (Simulated): The research team observed a statistically significant reduction in VAT (p peptide therapy for weight loss research.
GHRP-2 (Growth Hormone Releasing Peptide-2), with CAS 158861-67-7, is a synthetic peptide known as a growth hormone secretagogue. It acts as an agonist of the ghrelin/growth hormone secretagogue receptor (GHSR-1a). By binding to this receptor in the pituitary gland and hypothalamus, it potently stimulates the body to release its own endogenous Growth Hormone (GH). This mechanism makes it a key subject in studies on peptide weight loss therapy.
Our purity verification is a multi-step process conforming to rigorous scientific standards. The primary method is High-Performance Liquid Chromatography (HPLC), which separates the target peptide from any synthesis-related impurities. We guarantee a purity of ≥99.0%. Additionally, we use Mass Spectrometry (MS) to confirm the molecular weight and identity of the peptide, ensuring you receive the correct compound. A Certificate of Analysis (COA) detailing these results is provided with every order.
While all are GH secretagogues, they have different profiles. GHRP-2 provides a very strong GH pulse but can also slightly increase prolactin and cortisol. GHRP-6 also gives a strong GH pulse but is well-known for significantly increasing appetite (a ghrelin-like effect). Ipamorelin is more selective; it stimulates GH release with minimal to no effect on cortisol, prolactin, or appetite, making it a "cleaner" but potentially less potent pulse. The choice between them depends on the specific variables a researcher wants to study.
Storage: The lyophilized (freeze-dried) powder is stable at room temperature for short periods but should be stored at 2-8°C for up to several weeks. For long-term storage (months to years), it must be kept at -20°C.
Reconstitution: To prepare for research use, reconstitute the vial with bacteriostatic water. Gently inject the water down the side of the vial and swirl, do not shake. Once reconstituted, the solution should be kept refrigerated at 2-8°C and used within a specified timeframe (typically a few weeks) to maintain potency.
