There’s been a lot of buzz about peptides and what they can do for muscle growth, skin health, weight loss, anti-aging, and more. But what exactly are they, and do they live up to the hype?

Peptides are short chains of amino acids (the building blocks of proteins). Your body makes peptides, and you’ll also find them in some skincare products and dietary supplements. Lab-made peptides can mimic some of those found in the body, and they’re used in medications for conditions like diabetes and multiple sclerosis. They may even help boost muscle growth or speed up recovery from injuries.

While some people buy peptides without a prescription, it’s not recommended. Almost all online peptides for sale come from China, and research has shown that they’re often dosed in ineffective amounts or contain different compounds than they claim to have. To avoid these issues, you should always purchase peptides from a trusted source.

The best place to buy peptides is from a company that provides testing. You’ll want to look for a company that uses high-performance liquid chromatography to test every batch of their peptides. This is a common method of testing for quality and safety.

Another great option is to get a prescription from a wellness clinic that offers peptides for sale, such as Invigor Medical. These clinics can help you choose the right peptides and give you training, nutrition, and lifestyle guidance to maximize your results. They’re also able to provide you with a medical card for discounted or free treatment at a nearby healthcare provider.
