Carl grades Lekker Peptides: careful guides, then dosing schedules in the shop, 6/10

The short version: I'm giving Lekker Peptides 6 out of 10. Every one of the 28 papers its blog links to is the paper it names, every trial number I checked holds, and its legal guide is blunt: research peptides can't lawfully be sold for human use, and a “research use only” label isn't a loophole. Then the shop puts injection schedules on 48 “research use only” products, runs a protocols page with an “Add to My schedule” button, and has an open “Add to cart” on medicines its own guide says need a prescription. That's why both product checks are red.

What I looked at: lekkerpeptides.co.za, all 40 blog posts (16 read in full), all 189 product pages, the protocols page, goal pages, FAQ, regulatory page and policies. All on 15 October 2026. Before grading, I checked that Lekker Peptides has no link to us. It doesn't: the only overlap with our Lekker Latte brand is the word “Lekker”.

The score, broken down

The supplier checks

What they got right

Citations that check out. All 28 linked papers are the ones named, and every trial figure I checked against the original holds, from the retatrutide phase 2 trial to the semaglutide and tirzepatide weight-loss trials. The retatrutide post says it plainly: “Retatrutide is still investigational.”

It won't oversell in the blog. “anyone describing BPC-157 as proven is describing a rat”. Its side-effects guide says repair peptides have “few reported side effects, but also little human data”, and its COA guide warns that “A wall of perfect 100.0% figures is a warning, not a reassurance.”

It states the law against its own interest. Research compounds “have not been assessed for human safety, and it would be unlawful to sell them for human consumption.” And: “A supplier cannot make a research compound into an approved human product by describing it warmly.”

Honest about whose certificates they are, no fake reviews, careful shipping. The COA guide says its certificates are “copied exactly as the manufacturer printed them”. There are no reviews or testimonials anywhere, so none to fake. Cold packs and a 48-hour dispatch promise are the same on every page.

What dragged it down

The shop does what the blog says it can't. 48 product pages ending “For research use only.” carry injection schedules, “This is the dosing schedule supplied with the product”, missed-dose rules or “The supplied protocol is”. A protocols page gathers them under “How to use, as supplied with this product”, with an “Add to My schedule” button and “Speak to a doctor before starting anything new.” I'm not repeating any of their doses here.

Saved copies: protocols page (L11, L12, L13, L14, L15), tirzepatide page (L16, L17), Wolverine pen (L19), “ask us” (L22). All seen 15 Oct 2026.

Medicines with an open “Add to cart”. Its own legal guide says that if a compound is a registered medicine, buying it without a prescription isn't lawful, and its regulatory page defines “Prescription only, may only be supplied against a valid prescription.” The shop lists “Duromine 30”, described on the page as a “prescription appetite suppressant medication”, an “Elitox 100iu” listing with no description at all, growth hormone kits, and 27 semaglutide and tirzepatide listings, the molecules registered in South Africa as Ozempic and Mounjaro. None shows a prescription step on the page. I didn't open the checkout, so I can't say whether it asks for one there.

Names on SAHPRA's falsified-products list. In 2024 SAHPRA published a list of falsified or unauthorised GLP-1 products, including “Body Pharm Tirzepatide 30 Pen”, “Body Pharm Semaglutide 6 Pen”, HD Labs products, “Izempic” and iPharma tirzepatide. Lekker sells 9 listings with matching brand and product names, including “Tirzepatide 30mg Pen (Body Pharm)” and “iZempic 5mg”, the second described as having “the same active ingredient that made Ozempic and Wegovy household names”. A matching name doesn't prove it's the same product SAHPRA examined. But no post mentions SAHPRA's list, or its peptide warning naming all nine of the peptides SAHPRA calls illegally marketed, which Lekker also sells.

Benefit copy the blog would reject. Product pages say “Calms inflammation” (25 products), “Proven fat loss” (22) and “Accelerates recovery” (15). A menopause page sells growth hormone for “firmer skin, a leaner body and better energy” and calls its picks “the peptides women most often use to feel like themselves again”, then ends “All products are sold for research use only. Product pages carry guideline dosing”.

Facts that don't hold up.

The basics. No company name, registration number, address, phone or named person anywhere. The terms say “Our only contact channel is email” (L38). SA's online-selling law requires all of those details. The returns page says “We do not accept returns.” (L37) with no mention of the 7-day cooling-off right. 14 posts are dated before the domain was registered on 1 September 2026, with no note explaining why.

What would get them a better grade

• Take the injection schedules, missed-dose rules and “Add to My schedule” off research-use products, or stop calling them research use only.
• Remove prescription medicines from open sale, as their own legal guide says.
• Check the GLP-1 listings against SAHPRA's falsified list, and tell buyers about it.
• Publish the company details, and an independent lab report for each product, starting with the GLP-1s.
• Show the classification on every listing, as promised, and fix the retatrutide posts.

The writing is already good enough for a 9. The shop is what holds it back.

Their side

Lekker Peptides can reply any time through this form. If they do, I'll add it here word for word.

Spotted something I got wrong? Tell me. I fix facts fast and say what changed. I don't change a grade because someone complains, only when I've got a fact wrong or the supplier changes what they publish.
