Peptides Explained: A Plain-English Guide for South Africans
Peptides are all over social media, from skincare serums to injectable “recovery pens”.Â
The word covers everything from collagen powder to prescription medicine, which makes it all kind of confusing, but one thing that isn’t confusing, is how the term is dominating headlines and really creating a buzz in health-conscious circles.
In this guide, we’re talking about what peptides are, the main types you’ll see, and what to know before you buy.
What are Peptides?
Peptides are short chains of amino acids, the building blocks of protein.
Your body makes thousands of them, and they act as messengers that tell cells what to do.
Insulin is a peptide, and so are some modern weight-loss medicines.Â
Calling something a “peptide”, however, says nothing about whether it’s safe, effective or legal, which is why if you are curious about buying such products, you need to have a full understanding of the finer details written on the label.
The Three Types You'll Come Across
The Peptide industry is a burgeoning one, and it is hard to keep up with all of the products coming on the market. To keep things simple, products are categorised by how they are taken and these are the three types you will come across most:
1. Oral collagen peptides
These are the powders and capsules made from broken-down collagen, usually from cattle or marine sources and they're sold as food supplements. Some small studies suggest taking them can give you modest improvements in skin hydration and elasticity with daily use, though results vary and the research isn't conclusive. When shopping for these products, look for those that clearly states its source and the amount per serving.
2. Topical (skincare) peptides
Serums and creams containing ingredients like copper peptide (GHK-Cu) are cosmetics. They're applied to the skin surface, and the evidence for them is early and mostly from small studies. You should be really realistic with your expectations with these products, since while a good serum can support a routine but won't replace sunscreen, sleep or good nutrition. Always do a patch-test first, especially if your skin is sensitive.
3. Injectable "research" peptides
This is the category currently making headlines, and if you’ve been doing some reading up you might already be familiar with names like BPC-157, TB-500, CJC-1295, Ipamorelin, Melanotan II, Selank and Semax. They're typically sold as pens or vials and promoted for recovery, anti-ageing, tanning, focus or fat loss. Most of the research behind them comes from animal or early-stage studies, and long-term human safety data is limited (which is partly why there is such a big debate going on).
What South African Law Says
The South African Health Products Regulatory Authority (SAHPRA) has issued a public warning about unregistered peptide products.Â
It lists BPC-157, TB-500, Melanotan II, CJC-1295, Ipamorelin, PT-141, AOD-9604, Selank and Semax as illegally marketed peptides.Â
Under the Medicines and Substances Act, any product intended to treat, prevent or alter bodily functions must be registered with SAHPRA before it can be sold.Â
SAHPRA also warns against self-administration without medical supervision, especially for products bought online or from unverified sources.Â
An injectable peptide that isn’t SAHPRA-registered hasn’t been assessed for quality, purity or safety, so technically you can’t be sure what’s in the pen.
How to be a Smart Peptide Shopper
The goal of any supplement is to improve your health and to help you age beautifully, but naturally. When you are shopping around for peptides you should:
- Ask what category it is. Supplement, cosmetic or unregistered injectable are three very different things.
- Be sceptical of big promises. Phrases like “heals”, “reverses ageing” or “safe for everyone” aren’t backed by solid evidence.
- Look for transparency. Reputable brands share ingredients, amounts, manufacturing details and third-party testing.
- Check the claims against the research. A study on oral collagen doesn’t prove anything about an injectable.
- Speak to a doctor or pharmacist first. This matters most if you’re pregnant, on medication, managing a health condition, or considering anything injectable.
- Report side effects. SAHPRA accepts reports at adr@sahpra.org.za.
Peptides aren’t a miracle or a menace.Â
Some, like collagen powders and cosmetic serums, are low-risk additions to a healthy lifestyle when your expectations are realistic. Others sit in a legal grey area and carry real unknowns.Â
Understanding the difference will help you spend your money wisely and protect your health.

Frequently Asked Questions
What are peptides?
Peptides are short chains of amino acids, the building blocks of protein. Your body makes them naturally, and they act as chemical messengers between cells. They also appear in supplements, skincare and some prescription medicines, which is why the term covers products with very different safety and legal standing.
Are peptides legal in South Africa?
It depends on the type. Collagen powders and cosmetic serums are sold as supplements or skincare. SAHPRA, however, warns that unregistered peptides such as BPC-157, TB-500, Melanotan II, CJC-1295 and Ipamorelin are being unlawfully marketed, because health products must be registered before sale under the Medicines and Substances Act.
Do collagen peptides work?
Some small studies suggest daily oral collagen peptides may modestly improve skin hydration and elasticity, but results vary and the research is not conclusive. They work best as part of a routine that includes sunscreen, a balanced diet and good sleep, rather than as a standalone fix.
Is BPC-157 safe and legal in South Africa?
SAHPRA lists BPC-157 among peptides that are illegally marketed in South Africa. Most research on it comes from animal or early-stage studies, so long-term human safety data is limited. Anyone considering it should speak to a doctor first, as quality and purity of unregistered products cannot be assured.
How can I buy peptide products safely?
Check whether the product is a supplement, a cosmetic or an unregistered injectable, and be wary of claims that it heals or reverses ageing. Look for clear ingredient amounts, manufacturing details and third-party testing. Speak to a doctor or pharmacist first, especially if you are pregnant, on medication or considering injections.
