The peptides have good shelf lives especially when kept in the fridge, so just make sure the peptides dont change colour and use sterile techniques and the injections will be safe and effective. And if you are interested in the technique of injecting peptides, we have a video on the website, which goes through the details of how to do it safely and effectively. We supply needles and syringes with our peptides for your convenience. We provide our peptides premixed and that way we can maintain sterility and have a good shelf life. In Australia, it’s illegal to provide them as a powder as this relies on people mixing it themselves which are oftentimes contaminated in the process.
