Peptides Are Here to Stay: What Health-Minded People Need to Know in 2026

This article is part of the CrossFit BC journal, written by the coaching staff who run our classes in Olympic Village, Vancouver. We publish what we teach on the floor: training decisions, recovery, nutrition, and the honest tradeoffs behind them.

Common questions

What are peptides and how do they work?

Peptides are short chains of amino acids. Many act as signalling molecules involved in specific processes in the body. The term covers many different compounds, and evidence about one peptide should not be applied to another.

Are peptides safe to use?

Honest answer, we do not know enough yet. Most peptides have limited human trial data, and several of the popular ones are not approved by Health Canada for human use. Quality and purity in the grey market vary widely, so what is on the label is not always what is in the vial. This is a conversation for you and a licensed physician who knows your full health history, not something to decide from an article.

What is BPC-157 used for?

BPC-157 is discussed in connection with tissue repair, inflammation, and gut health. Most supporting evidence is preclinical, and BPC-157 is not authorized by Health Canada for human use.

Are peptides legal in Canada?

Several of the peptides discussed here, including BPC-157 and TB-500, are not authorized by Health Canada for human use. They are commonly sold as research chemicals, which sits outside the regulated supply chain and outside any quality oversight. CrossFit BC does not sell, supply, or recommend suppliers of peptides. If this is something you are considering, take it to a licensed physician.

What is the difference between peptides and steroids?

Peptides signal your body's own processes, such as stimulating growth hormone production or tissue repair. Anabolic steroids are synthetic hormones that override those systems. That is a real mechanical difference, but it does not make peptides risk free or well studied. Different is not the same as safer.
