Wrong address

Hello,

I am contacting you regarding my order that was shipped from the UK to Portugal. The parcel is now being returned to the country of origin because the door number was missing from the address.

I would like to ask if it is possible for you to resend the parcel back to Portugal, this time adding the correct door number to the address. I can provide all the necessary details, including the order number, as soon as you respond.

If reshipment is not possible, I kindly request a full refund, as the order cost me €80.

I have already tried contacting your support by email, but I have not received any reply. I would really appreciate your help in resolving this issue as soon as possible.

Thank you,

Hi, I'm a bit confused by the two stars. You've already said the address was incorrect and we printed the label exactly as it was entered at checkout. Our system prints everything automatically so we rely on the customer details being right.

I've replied to your email as well. We can't resend a parcel until it comes back to us. Once it's returned we'll get in touch and you can choose either a resend and just cover the postage, or a refund minus the shipping cost.

We sent your order out on time and followed everything as normal, so it's a bit disappointing to be rated low for something caused by the address details. Happy to sort it for you as soon as it lands back with us.

Very Happy..Peptides work as they should.

Used this company a few times.. started with a big batch of semorelin to get my feet wet.. and then moved on through to to CJC with Dac stacked with Ipamorelin.. I'm 60 and over a few months cycling on and off you def see substantial improvement across the board.. sleep.. especially strength and now body recomposition.. The Peptides work when used correctly with diet and training and proper disciplined sleep protocol. I want to step up to tesamorelin for my next cycle in a few weeks just a shame they're out of stock and their tesamorelin is very expensive..I'm sure you get what you pay for though.. searching other sights hope to find one as good a UK PEPTIDES

Be Careful with the precedence - I got allergy reaction

I have been buying CJC-1295 and Ipamorelin from this company for about 3 weeks. Th first week I got a strong allergy reaction in my left leg, where I applied the product. I had to go to the doctor and gave me an antibiotic (because it was the first time, we thought it was an infection).
However, today straightforward when I applied, my entire body started to itch, got swollen, red rash entire body, face, and it was like burning.
I took an anti-allergy tablet, and I went to the hospital immediately. Due to the case that was urgent, the doctor saw me very quickly. The doctor said it was an allergic reaction since the first time I applied because of the substance inside.

Now is the question, (real) peptides are not supposed to give any allergic reaction. Now I am totally in doubt about the precedence of these labs.

I handled and stored everything properly. The problem is with the product. For the first time, I bought CFC1295 with DAC, to avoid many injections. But after the first allergy reaction, I decided to buy without DAC. But now, it was in ht entire body.

I found a clinic in London that does Peptide Therapy, I will try them, probably it will be safer. I am totally disappointed with this situation and what I have gone through today.

Hi Brian,

We’re sorry to hear about your experience, but as explained in our emails, customs delays are completely outside our control. We always work with customers who follow our process, offering a refund or reshipment once the parcel’s status is confirmed.

We have many customers in Ireland who receive their orders without issue, and it’s disappointing to have our reputation affected by postal or customs problems that no business can control. We always make sure no one goes empty-handed.

Rated 1 out of 5 stars

Fake.

Nothing worked for me i can't help but think they are all fake or at least a majority are. I'm going back to my old supplier. The third party test certificates are easier to fake than the peptides. I've been taking bpc157 and related peptides for a while along with motc, and pt141. I had no suttle effects from any of them. I won't be back.

Not a completely bad experience

Not a completely bad experience. The products might work. Haven’t used them long enough. My only concerns are when I asked the fella where he sourced them from. He said he couldn’t tell me when every other company I called had told me directly. Also COAs are in-house which is very shady in my opinion because those machines are worth 10s of thousands of pounds. So why not just go to an external source or provide COA services to other company’s to make back your money.

Hi,

We’re disappointed to see the 2-star review, especially considering your order was dispatched quickly and arrived without issue.

Just to clarify, we’ve been selling research peptides for over 15 years and don’t source from resellers or underground labs. The testing is carried out by our long-term compounding facilities, which we’ve partnered with for over a decade. No professional company in this industry would disclose their exact source, as NDAs are in place for compliance and confidentiality reasons. It’s the same principle as a pharmacy you wouldn’t expect them to reveal which facility compounds their products.

The COAs we provide are created using raw data from our compounding partners. These represent the minimum purity level we would accept before approving a batch for sale, meaning the actual quality is often higher. In 2026, we plan to install our own analytical equipment, valued at over £150,000, to further expand our on-site testing capabilities.

As we move through batches weekly, sometimes daily, it wouldn’t make sense to pay £300+ per test to third-party labs when our trusted facilities already perform full analytical work. Transparency has never been an issue for us in fact, we always encourage researchers to send samples for independent verification if they wish.

It’s a shame the review didn’t mention the professional setup we operate from, including temperature-controlled storage and walk-in freezers, all shown on our About page. One vial will rarely show noticeable results in short-term studies, so we hope future reviews focus on actual research findings rather than assumptions.

We take pride in the quality of our products, service, and aftercare. Best of luck with your ongoing research.

Let me know if there’s anything else you need.

Very good company

Very good company, discreet packaging which is very well packaged too. Quick delivery and no issues with the products. If I have to say anything, which isn't a negative but something to think about, need more products at 10mg or more. Things like Tesa at 2mg isn't viable seeing as most research is done at 2mg. Same with other items where a higher dose is needed.

European shipment not possible

I wasn’t planning on writing a review, but seeing that they’re still selling peptides to countries where they’re outright banned, I feel I need to warn others before they make the same mistake.

I honestly wasn’t aware — most places online describe peptides as a “grey area,” where they’re not really legal but not really illegal either. However, in Europe they are banned.

After ordering GHK-Cu, BPC-157 and CJC-1295 (No DAC) + Ipamorelin, I was contacted by the police, hit with a massive fine, and officially warned that trying to import again would lead to severe consequences for illegal import of doping/medicine.

So if you’re in Europe and considering ordering, be aware: this can get you in serious legal trouble.

Thank you for your review.

We understand your frustration, but customs laws vary by country and it’s always the customer’s responsibility to check local regulations before ordering. We ship hundreds of parcels each week to international research clients without issue, and these products are not classed as medicines.

We did reach out at the time and advised how you could appeal the customs notice, but you chose not to proceed. Had you sent them our response, the parcel would likely have been returned and we could have refunded you.

We dispatched your order the same day payment was received and kept you updated throughout, so it’s disappointing to receive a 1-star review for something outside our control.

Let me know if there’s anything else you need.
