AI Review Summary
Based on recent customer reviews, Leolab generates strongly polarised feedback within the South African peptide and GLP1 space. Satisfied customers consistently mention impressive weight loss results, fast delivery, and responsive pre-sale support, with several describing the product quality as life-changing. However, a recurring theme among critical reviews is concern around reconstitution materials being sent in place of bacteriostatic water, hand-applied or missing vial labels, alleged false advertising, and unanswered post-purchase queries. Trust, safety, and after-sales communication emerge as the central tensions shaping the customer experience.

⚠️ WARNING: LEOLAB Dangerous Reconstitution Supplies. Do not use
If you are buying peptides from Leolab, note that they are one of the most dangerous suppliers I have dealt with. They send you items which, according to all research, SHOULD NOT BE USED to reconstitute the peptides. The water increases the risk of bacterial growth. I ordered 3 vials of peptides. They sent me 1 vial of bacteriostatic water and 2 vials of sterile water. STERILE WATER LIKELY LEADS TO BACTERIAL GROWTH WITH MULTI-USE. IT IS NOT INTENDED FOR MULTIPLE USE, BUT RATHER SINGLE USE WITHIN A DAY. Here is a quote (multiple sources state it is not suitable): "Sterile water is primarily intended for single-dose applications, often packaged in small, single-use vials. Once the seal is broken, the water is immediately susceptible to microbial contamination from the surrounding air or the syringe used for withdrawal." https://scienceinsights.org/can-i-use-sterile-water-instead-of-bacteriostatic-water/ This is the SECOND TIME this has occurred. In the last order, they sent saline water, which is also only meant for single use and does not stop bacterial growth. If you are ordering from them ensure you confirm they are sending you BAC WATER, or make sure you get BAC Water, as it is not safe to be reconstituting with what they send you. There are only a few peptidwa where the recommendation is to not use BAC WATER. oxytocin , desmopressin:, Vasopressin, HCG, GLP1

Poor poor poor and very dangerous to even regard them as professional.
They sent me Vials with labels hand pressed on to the vials. One vial without a label. First they say it is Acetic Acid then i ask where is the product i ordered. Then after back and forth emails they say no it is the product i ordered they ran out of labels. Labels are skew. Nothing Pharmaceutical about these guys sending stuff from Hartbee****rt But listed as a SANDTON company. I have no trust to use this stuff that looks like a 7 year old put a label on. Poor poor communication! Look at their other reviews. Should have come and checked there first. Waste of R9000 - Their response is pathetical and slow. One person **** MILKING people!!!

Unbeatable service quality wherever i travel
Leolab has delivered consistently excellent service for me in South Africa, the UK, and the US. As a frequent business traveler, I really value that the service quality stays the same everywhere—fast, reliable, and unbeatable. Their support team is highly skilled and responsive, even on weekends and holidays, and the peptide quality is top-notch.

Best peptide vendor i’ve used in SA
Most reliable peptide vendor in SA, in my experience. I’ve been a peptide user for 2+ years and have tried multiple sellers — I’ve even been ****med once, and other issues took weeks to resolve. With Leolab I’ve done 10+ orders and only had one issue, and they replaced it within 2 days. Solid service and consistent delivery.

Leolab **** ????
I decided to rather support a local company than an overseas company and after looking at reviews on multiple sites I decided to go with Leolab. They advertised the 30gm peptide I was interested in as 3 x 10mg vials and even though I knew the product would be less effective, it made financial sense to purchase 3 x 10mg vials. When I enquired about the dosage I should take on the 10gm vials, Leolab informed me that it was only 1 x 30gm vial. This is not what they are advertising on their website hence I cancelled my order. Leolab informed me that they will cancel my order immediately and refund me asap, even though they didn't even ask me for my banking details. I mailed them back with my banking details and since then I haven't received any feedback from them and no need to say I haven't received my refund. I've tried to mail them, What's App them and phone them on the only number available on their website, without any response. Have I been ****med or is Leolab legit and they just don't care about after sales service and taking liability for false advertising. No wonder the public rather support overseas companies.

Life-changing peptides with minor transparency gaps
Leolab has delivered excellent results for me, especially in terms of weight loss. Their peptides have honestly been a life-changer and made a noticeable difference in how I feel and perform day to day. The only downside is that the third-party test results published on their site appear to be outdated. If having the most current lab tests is important to you, you’ll need to reach out to them directly through their contact channels to request the latest ones. Overall, great results and a strong product, with some room for improvement on transparency and updates.

Dangerous to purchase from here
Beware dangerous to purchase from here. So I have previously purchased from a few suppliers, leolab unfortunately service is lacking, but even worse it could also be dangerous. I ordered CJC/ipamorlin & AOD9604 , two vials. Previously I had confirmed with them that you get everything necessary. So they sent me one vial of 3ml bariostatic water, and Sabax Sodium Chloride at 0.9%. No instructions included with the item, or on email. In any case I thought maybe AOD9604 needs to be reconstituted with the Sodium Chloride. I thought I would check Gemini for details. Here is the result “This ampoule contains preservative-free saline, not bacteriostatic water. Once opened and used for reconstitution, it provides no protection against bacterial growth, making multi-dose storage unsafe and increasing infection risk. Additionally, saline can reduce peptide stability, and with peptides like AOD-9604, it may cause cloudiness or clumping, indicating poor dissolution and potential degradation.” The issue was mailed through on Saturday, and it’s Tuesday and yet to get a response. Next, before I purchased I inquired if they provide everything for the full course. this meant 1. Bariostatic water for reconstitution 2. The needle for constituting 3. Insulin syringes for the course 3, alcohols swabs They confirmed via email , yet I did not receive everything. When I followed up (multiple times), I received no response.

Avoid!
Customer service is absolutely terrible! They only reply before you buy a peptide. And this is not even the worst thing about them. My peptides arrived yesterday afternoon, after being out for delivery for the entire day. They should be kept 2-8c while in lyophilized form, they were warm when i received them. It’s summer now. I tried to reach out, no reply. I reconstituted the peptide, pinned in the evening. Allergic reaction. Itchy hands and feet, with also allergic reaction around injection site. One day after, i again try to reach out. No reply. I messaged again explaining what happened to me, no reply. I am being ignored, while i paid for the peptide, had allergic reaction to it, and trying to talk to them. So their business is all about money, they don’t care about customers at all. They even send peptides without any instruction on how to reconstitute them or how to use them, so you have to do all the research yourself.
