What Are BPC-157 & TB-500?
A Recovery Peptide Guide

BPC-157 and TB-500 are the two peptides most associated with injury recovery and tissue repair. They have become popular with athletes and active people, but the science, the safety picture and the anti-doping rules are widely misunderstood. This guide explains what each one is, how they differ, what they are used for, the honest state of the evidence, and how to start on a doctor-led programme in South Africa.

Everything here was reviewed by Dr Chris van Zyl (registered as M.C. van Zyl, HPCSA MP0287067), who is licensed to both prescribe and dispense medicines under a Section 22C dispensing licence. Recovery peptides are dispensed on a valid script after a medical questionnaire, with a consultation arranged when your screening calls for one.

What is BPC-157?

BPC-157 stands for Body Protection Compound-157, a chain of 15 amino acids derived from a protein found naturally in the stomach. In laboratory and animal studies it appears to support the formation of new blood vessels and the repair of connective tissue, which is why it is used for tendon, ligament and muscle injuries and for gut health. It is important to be clear that most of this evidence is preclinical, so BPC-157 is best understood as recovery support rather than a proven cure for any condition.

What is TB-500?

TB-500 is a synthetic version of a fragment of thymosin beta-4, a protein your body produces that plays a role in cell repair, migration and building new tissue. Where BPC-157 is often thought of as targeted, TB-500 is used for broader, whole-body recovery, mobility and flexibility. As with BPC-157, the human evidence is limited, so it is used under medical guidance as recovery support.

What is the difference between BPC-157 and TB-500?

The simplest way to think about it: BPC-157 is local, TB-500 is systemic. BPC-157 is used to support repair at a specific site, such as an injured tendon or the gut lining. TB-500 circulates more widely and is used to support whole-body regeneration and flexibility. They work through different mechanisms, which is exactly why many people use them together rather than choosing one.

Why are BPC-157 and TB-500 used together?

Because they complement each other. BPC-157 supports focused, local repair while TB-500 supports broader, systemic recovery, so a combination covers more of the recovery picture than either alone. This is why mobivIVe offers a BPC-157/TB-500 combination pen alongside the single peptides. Your doctor will advise whether a single peptide or the combination suits your situation.

What injuries and conditions are recovery peptides used for?

The most common uses are soft-tissue injuries: muscle strains, tendon and ligament problems, and slow-healing niggles that limit training. BPC-157 is also used for gut-related support. People recovering from surgery or managing a stubborn injury use them as part of a structured recovery plan. They are support tools, not a replacement for physiotherapy, rest and proper rehabilitation.

Does BPC-157 help with gut health?

BPC-157 is derived from a protective stomach protein, and much of the early research looked at the digestive tract, which is why it is popular for gut support. People use it for general gut comfort and recovery. The same honesty applies here: the supportive evidence is largely from animal studies, so it should be used under medical guidance rather than as a treatment for a diagnosed gut condition.

How long does a recovery peptide protocol take?

Protocols are typically run over a number of weeks, with the doctor reviewing progress along the way rather than following a fixed calendar. Chronic or long-standing issues generally need longer than a fresh, minor strain. Consistency and pairing the peptides with proper rehabilitation matter more than any single dose.

Are BPC-157 and TB-500 safe, and what are the side effects?

In the available studies both are generally well tolerated, and with the prefilled pen side effects are usually limited to mild reactions at the injection site. The honest caveat is that long-term human safety data is limited, which is precisely why they are dispensed on a script after a doctor reviews your history, rather than sold over the counter.

Are BPC-157 and TB-500 allowed in sport?

No, not for competitive athletes. Both BPC-157 and TB-500 are on the WADA Prohibited List and are banned at all times under anti-doping rules. An athlete can face a ban even without a positive test, based on possession or admission. Recreational, non-competitive use is a separate matter, but if you compete under any anti-doping code you must not use them and should check with your governing body.

Who should avoid recovery peptides?

Recovery peptides need careful medical assessment, and may not be suitable, for anyone with an active or hormone-sensitive cancer, and for women who are pregnant or breastfeeding, unless a doctor advises otherwise. Competitive athletes bound by anti-doping rules should not use them. This is why they are dispensed on a script after a questionnaire and doctor review.

How do I get BPC-157 or TB-500 in South Africa?

Recovery peptides are prescription items, so it starts with a short medical questionnaire that our registered doctor reviews, with a consultation arranged when your screening calls for one. Once a script is issued, your prefilled pen is couriered anywhere in South Africa with clear dosing instructions. Pricing and the full options are on our recovery peptides (BPC-157 and TB-500) page.
