  1. How to Mix Peptides

    Peptides are currently being used around the world for countless types of scientific research. Some of these peptides are used singly within the research, but other experiments require numerous peptides to be mixed together in order to see what type of results the experiment will yield. When it comes to mixing peptides, researchers have to be quite careful so as not to mix them the wrong way, as that could have dangerous results. Here are some tips on mixing peptides properly.

    How to Properly Mix Different Peptides

    When peptides need to be mixed, they have to be in like forms. This means that if a researcher is trying to mix two (or more) peptides, for example, he or she must use both peptides in a liquid state. When shipped, most peptides are in a solid, dry state. This allows for the best preservation, and keeps the integrity of the peptides the highest, thus ensuring the most accurate results possible for each type of experiment. The peptides must then be diluted into their proper states, typically liquid, before any combination can begin. If the peptides were shipped in a non-concentrated form, diluting into a different state is unnecessary. However, peptides shipped like this often have a very short storage life before they begin to lose integrity for research. This makes time become the essence during any type of experiment so that the results are accurate and repeatable. If too much time elapses between receipt of the peptide and the experiment, the results may not only be wrong, but the peptides could begin to degrade enough to where a normally standard experiment could become dangerous. When combining two liquid peptides, both liquids should be extracted by using separate sterile syringes, in the proper quantities. Once both liquids have been extracted into the syringes, they should be combined according to the manufacturer's instructions in a sterile dish or container. Typically the liquids will need to be gently swirled together, but some with thicker viscosity may need a little agitation to combine. Once the peptides are together in a homogeneous solution, they can be used for research into what the combined properties of the peptides do during the experiment.

    Safety When Mixing Peptides is Key

    While no method of peptide mixing is completely safe 100% of the time, following the manufacturer's instructions exactly is the only way to ensure the safest results when mixing peptides. These are always included with the purchase of a peptide from a reputable company, and should be followed precisely. Even skipping a single step can not only give false research results, but it could also lead to unsafe conditions. No matter what types of peptides are being mixed, care must be taken to ensure the safety of everyone around the experiment. This includes those that are mixing the peptides directly, and those that are in the vicinity. Peptides that are mixed improperly have the potential of exposing researchers to dangerous conditions, on top of the humiliation that could come with inaccurate results should another researcher try and recreate the experiment and prove the initial results wrong. Each type of peptide is going to have different requirements, depending on the quality, quantity, and manufacturer. This is why following the specific instructions from each manufacturer is so vital. Researchers that take the time to read through the instructions before setting up any type of an experiment are going to save time, money, and potentially a lot more should they miss any special instructions that the manufacturer included. Making sure to combine when the peptides are in similar states and under the safest of circumstances will allow for researchers to have the most dependable and reliable experiments possible.
  2. What is Anastrozole?

    Anastrozole has been in the news a lot over the last couple of years. This is due to the advancements it has shown in research at helping avoid breast cancer in test subjects that are prone to the disease. Scientists have been able to learn a lot about how this enzyme works recently, which may open up new research opportunities in the future in breakthroughs for breast cancer treatment. Here is some information on how Anastrozole has come into the spotlight.

    What Exactly is Anastrozole?

    Anastrozole is a drug that is currently being studied to see how effective it is at reducing the amounts of different hormones within female test subjects. The focus is currently surrounding hormones that are typically responsible for reproduction in female test subjects, and how those hormones can be inhibited or stopped altogether. There has been a significant link found between higher hormone levels and increased risk for breast cancer, so scientists are trying to focus their experiments on test subjects that have gotten past their reproductive years, but there is also a lot of promise being shown in subjects that are also undergoing other types of cancer treatment. What has been found so far is that the inhibiting factor that comes with consistent doses of Anastrozole is lowering the growth potential for certain types of tumors that are often a part of a breast cancer diagnosis. When Anastrozole is not given consistently, the test subjects are not seeing the same type of progress or decreases in tumor size, but a standardized dose has not yet been discovered. Researchers are working mostly on female rats at this point in time, but the research has shown a lot of promise at helping scientists map out what these tumors need to grow successfully.

    How Does Anastrozole Work?

    So far research has shown the most promise in female test subjects that are beyond their reproductive years. It works specifically by reducing the production of female hormones, which are thought to be one of the main contributors to breast cancer in older female subjects. Anastrozole is given in different dosages depending on how large the animal is, and has shown promise in keeping breast cancer cells from forming. This is especially true in those who have some sort of predisposition or genetic predilection to cancer before the trials began. Anastrozole also inhibits how much of the hormone that is left in the body is able to be absorbed by the body. So far, this has shown scientists that breast cancer tumors are not able to grow as quickly or as large. This has led to additional types of research where scientists have been trying to see what happens to the cancerous tumor if more types of hormones are removed or decreased from the bodies of test subjects. This is helping researchers map out the requirements each type of tumor has in order to flourish. Anastrozole has the potential to teach scientists a lot about how breast cancer forms and what types of cells and hormones it requires in order to take over the body of a test subject. The more research that is able to be done on different test subjects, the more potential information scientists could come up with for battling the disease on a larger scale. Warning: Peptides are never intended for any type of human consumption, and could be dangerous if used improperly. Peptides are solely intended for scientific research, and should not be used in any fashion other than how they were intended. Care must be taken to avoid exposure, including but not limited to protective eyewear and clothing, and proper research techniques.  
  3. How to Properly Store Peptides

    When it comes to properly storing peptides, each one is different. Some peptides need to be stored in dry forms, while others remain in a liquid form for ideal storage. When a researcher uses different forms of peptides, it becomes imperative to know which type is being used so the peptides remain fresh and dependable. Here is a breakdown of proper storage procedures for both dry and liquid peptides.

    Storing a Dry Peptide

    When a peptide is shipped in a dry form, there are two storage options. First is leaving the peptide at room temperature for a short-term storage solution, but this only works if the peptide is room temperature stable. This should be something included from the manufacturer when the peptide is sent. If the peptide is not stable for room temperature storage, the next option is cool storage for the short-term. Typically keeping peptides below four degrees centigrade is cool enough for storage for a few months. However, if your dry peptide needs to be stored for longer than that, the temperature should remain below -20 degrees centigrade. Dry peptides should also be stored out of direct light, no matter if they are stored at room temperature or if they are stored at a refrigerated temperature. Lights of all kinds decay peptides, some faster than others, and can cause them to become unstable and unreliable in a very short amount of time.

    Storing Peptides as Solutions

    Liquid peptides are a bit more difficult to store for the long term. Typically short-term refrigerated storage is enough for liquid peptides, but if long-term storage is required, most peptides require freezing in a freezer kept at or below -20 degrees centigrade. This helps keep peptides from oxidation and degradation, allowing the peptide to remain more stable and research to be conducted without the concern of skewed results. However, researchers may want to freeze peptides in the quantities they experiment with so that the peptide does not undergo consistent freezing and thawing cycles, as this can cause permanent damage and degradation to all frozen peptides. Frost-free freezers repeatedly cycle on and off to keep frost from building up on the inside of the freezer, making the temperature unstable. Due to the damage this can cause the peptide, this type of freezer should also be avoided. In order to give liquid peptides the longest available shelf-life for use, storage must be a careful consideration prior to ordering peptides so that there is no lapse in temperature stability during the shipment and receipt process.

    Peptide Storage Containers

    When it comes to storing any type of peptide, one must also keep the container in mind. The container should be clear or translucent, resistant to chemical breakdown, strong enough to withstand moving the peptide around when using it, and made in a size that is fitting for the amount of peptide being stored. Most researchers choose glass; however, some types of plastics are also suitable for peptide storage. If peptides are stored properly, they are able to remain fresh for a longer period of time. The fresher the peptide, the more accurate of research results will come from all experiments using the peptides. If any peptide is used beyond its ideal freshness time frame, it could throw off all of the results and make the experiment unable to be duplicated. Every peptide requires careful storage so make sure that each peptide is stored according to the specified instructions, and if a peptide is not stored properly, do not use it in any form of research. Instead, dispose of the peptide in the method recommended by the manufacturer and order a new supply. It is important to read the manufacturer’s guidelines and ensure you are following the recommended storage guidelines.
  4. 7 Reasons Peptides Made in the USA Are Better

    Hormone glucagon 3D molecular structure Peptides are short chains of amino acids, and can be thought of as smaller versions of proteins, which are also made up of linked amino acids. Peptides have been identified as and are increasingly utilized in several scientific areas. Peptides can be used to isolate protein antibodies in animal research, or small, synthetic peptides can be used to test protein interaction with other peptides. Recently peptides are also being studied as potential candidates for use in treating prostate cancer by inhibiting the uptake of growth hormones. Researchers are beginning to understand the possibilities inherent in peptide experimentation. As such, peptides are increasingly in demand and under elevated levels of scrutiny by regulatory authorities. Key among the decisions that researchers make during experimental design is the source of their peptides. Peptide manufacturer selection is crucial, as it can significantly affect the outcome of an experiment if the test substance is impure or diluted. In this highly competitive research landscape, American-made peptide manufacturers are differentiating themselves in a variety of ways, and are standing out as the producers of the highest-quality research-grade peptide products currently available. Put simply, among the other reasons for choosing an American peptide manufacturer is the notion that the scientist, with a US-made peptide test substance, researchers can expect:

    1) Rigorous Certification:

    All peptide manufacturers in the United States are required to undergo a rigorous and thorough assessment of manufacturing processes to ensure only the highest quality product is produced. This assessment, which usually results in a standing and renewable certification for the manufacturer, ensures that all purchasers know and are comfortable with the standards under which the manufacturer operates.

    2) Testing and Auditing:

    Similar to the certification process, which establishes that a manufacturer operates under guidelines at least as stringent as the baseline of the certification requirements, testing and auditing procedures are performed on US peptide labs to ensure quality as well. Despite clean facilities and good intentions, processes, procedures, and equipment can drift from their originally intended uses, resulting in errors and contamination. Regular testing and auditing as required by US regulatory agencies will ensure that there is no drift.

    3) Supporting American Science:

    In a world where cost is often the bottom line, US-made peptides are produced in the United States by American scientists. Not only does your purchase of US-made peptides ensure the continued viability of manufacturing in the United States, but it also supports science and educational research initiatives both by employing trained American scientists and by making US-produced peptides available to American researchers for testing and experimentation.

    4) Dilution:

    US-made peptides are as strong and potent as researchers might expect. One concern for manufacturers outside the United States is reduced oversight, which can lead to significant cost avoidance in the form of product dilution; making the product less potent by adding other agents influences the research being done in potentially catastrophic ways.

    5) Shipping and Customer Service:

    Manufacturers of peptides outside the United States may cost less, but purchasing peptides from US-based manufacturers often results in drastically reduced shipping fees and shipping times, with your peptides ending up in your hands more cost-effectively and in a more timely manner than other solutions outside the United States. Additionally, many US manufacturers provide US customer service solutions to their customers.

    6) The Process:

    The best of the best of United States peptide producers utilize not only American raw materials, but also American equipment and American packing materials. Each of these components undergoes the same stringent quality standards, resulting in a purer and purer end product.

    7) Purity:

    In order to be confident of experimental results, purity is key. Contamination by other substances can be harmful to the research being done, and can introduce errors or distracting results into a study. The rigorous American certification processes undergone by US manufacturers ensure that product purity will be of the highest order possible and exactly as advertised. For many researchers, cost is the bottom line when determining study design and the application of funding. But ensuring that only US-produced peptides are used in research represents a valuable investment in the integrity of data and of the results, and in the end can prove much more valuable.
