The short version: I'm giving White Rabbit Labs 4 out of 10. Their disclaimer is thorough, one product page is a model of honesty, and the one study they summarise in detail is quoted accurately. But the site says it gives no dosing guidance and then gives it, in its own guides and on product pages. Dozens of listings read like health claims, there's no lab report anywhere, and the “sources” sections list topics instead of studies.
What I looked at: whiterabbitlabs.co.za, all 4 PDF guides on their Education page (22 pages), 35 pages in full including product, category and policy pages, and the text of all 124 products in their catalogue. All on 14 October 2026. They have no blog, so the guides and product pages are what I graded.
The score, broken down
| What I marked | Score | Why |
|---|---|---|
| Is it clear? | 1 / 2 | The handling guides are plain and well laid out. But pages contradict each other and themselves, and the guide titles on the Education page don't match the PDFs you download. |
| Is it useful? | 1 / 2 | Mixing and storage basics are explained properly. The growth hormone guide is mostly “best for” and “best stacks”, and the tirzepatide pages have no description at all, just a benefit line. |
| Are the facts right? | 1 / 2 | The study figures they quote are right. Their absorption claim is wrong for two products they sell, and the cancer guide stretches a mouse study further than it went. |
| Does it show the evidence? | 0 / 2 | Two real citations across the whole site. The “Citations and Sources” sections list research topics, not studies. |
| Is it honest about downsides? | 1 / 2 | The AHK-Cu page is honest about thin evidence. But side-effect sections say “not applicable”, and the growth hormone guide promises “fewer side effects” with no risks listed. |
| Total | 4 / 10 | Careful in places, contradictory everywhere else. |
The supplier checks
| Check | Result | Why |
|---|---|---|
| Lab reports | Red | The home page mentions “COAs where available”. I found none: no lab name, batch, date or verify link on any product. |
| Claims & dosing | Red | Benefit lists like “Lung Repair” and “ADHD relief”, categories named after conditions, dose schedules on product pages and injection technique in the guides, all on research-use products. |
| Basics | Amber | Email, WhatsApp, refund policy and terms. But no street address, company name, registration or VAT number, no shipping policy, and terms that name a different company. |
What they got right
A disclaimer that means it. Every page carries a clear notice that the products aren't approved and aren't for human or animal use, and many product pages repeat it in detail. Most shops do a one-liner.
One properly honest page. The AHK-Cu page says published work on it “is limited”, names the one study behind it, says there are no human trials, and warns not to borrow evidence from the better-studied GHK-Cu. I checked that study: they describe it accurately. More pages like this would change the grade.
The study they summarise is quoted right. Their cancer guide reports a 2025 mouse study of retatrutide, and the headline tumour numbers match the paper. The mixing and storage guide is also clear and sensible.
What dragged it down
“We don't give dosing guidance”, then dosing guidance. 56 of their 124 product descriptions say White Rabbit Labs “does not provide dosing, usage, administration” or reconstitution guidance. The Education page calls its guides resources “without personal-use guidance”. But the HCG page sets out dose schedules for use alongside testosterone therapy, the GHRP-6 page says how often it's injected, and the guides cover injection angles, needle sizes, rotating injection sites and this line, from the mixing guide:
“Start with a low dose on your first injection to test tolerance.”
Listings that read like health claims. 44 of the 124 products have a short description that's just a list of benefits, with no research framing at all. Chonluten: “Lung Repair”. Thymosin Alpha-1: “Viral Relief, Vaccine Booster”. Tesofensine: “ADHD relief”. Every tirzepatide strength: “Fat-Loss Reduced Cravings” and “Improved Insulin Resistance”. The shop also has categories called “Anxiety and Depression”, “Neuropathy” and “Lung Damage”. On the HGH page, the benefit list sits right above a paragraph saying those same things “must not be understood as claims”.
No lab reports. The home page offers “COAs where available”. I didn't find one on any product page, and the text of all 124 products never names a lab, a batch or a test date. The cancer guide promises products “manufactured under strict quality control standards” without saying which.
Facts that don't hold up.
| What they say | What I found |
|---|---|
| Injections under the skin give “approximately 95-100% bioavailability” with “almost zero loss” (E13) | Not for the products they sell. The official labels put tirzepatide at 80% and injected semaglutide at 89%. |
| The researchers concluded triple agonists may protect against “non-obesity-linked cancers” (E18) | The study only used obese mice, so it couldn't show anything about cancers in lean bodies. Some of the protection also faded once the drug was stopped, which the guide doesn't mention. |
| “Why We Don't Supply AOD-9604” (E15) | AOD-9604 is listed in their shop, under Fat-Loss (E16). |
Sources that aren't sources. The retatrutide pages have a “Citations and Sources” section that lists research areas like “GIP receptor pathway research”, with no study, author or link (E11b). Across the site I found two real citations. A claim that “nearly 76% of users” preferred a thinner needle names no survey at all.
Copy-paste errors. The retatrutide 10mg page talks about “Reta 15mg” (E11). The AHK-Cu 100mg page describes “a 50 g vial”. Retatrutide 30mg is listed as “Retatutride”. Small things, but on a page about measuring milligrams, they matter.
The basics. There's an email, a WhatsApp number and a contact form, but no street address, no company name, no registration or VAT number, and no shipping policy. The terms say “Modern Aminos may update these Terms at any time”, which is another company's name, and use US legal wording about federal and state law (E19). The terms say you must be 21 to buy, while their WhatsApp group page says 18. Peptides can't be returned, refunds carry a 15% restocking fee, and the refund policy says chargebacks “will be treated as fraud” (E20).
What would get them a better grade
- Make the pages match the disclaimer: take out the dose schedules, injection technique and “first injection” advice, or stop calling it research use only.
- Replace the benefit lists and condition-named categories with neutral research descriptions.
- Publish real lab reports from a named lab, per batch, with a way to check them.
- Turn “Citations and Sources” into actual citations, and fix the absorption claim.
- Do the AHK-Cu treatment for every product: what's known, what isn't, and the main study.
- Publish an address, company details and a shipping policy, and fix the terms that name another company.
Do that and I'll grade it again, here, in public.
Their side
White Rabbit Labs 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.
