They are great! I received a quick and good response. Products are on another level. The shipment is fast. They have tests for heavy metals and endotoxins for some of their products.

Rated 5 out of 5 stars

My research solutions turned out great, dissolved clear and fast. Communicative, attentive, decent pricing, very good website and order UI - what else could you want? give it a try.

Impressed with all the COA’s (HPLC, endotoxin, sterility and heavy metals)

I've really been into peptides in the past six months and I've tried a lot of different EU brands, but honestly I have had the best experience with Crystal so far. I've made a couple of purchases from them already and the delivery was fast, products seem to work especially the Reta and GHK-cu. I have only one complaint and that’s with the PT 141 nasal spray which I’m not really happy with, this one I don’t recommend, no effects for me at least. Objectively the thing that impressed me the most is that the not only have the HPLC test for purity and identity which is a must obviously, but they also have included endotoxins, purity and heavy metals lab test which I have never seen other brands incorporate. Also they work with Janoshik lab test which is the gold standard in the industry so that’s bonus points. Overall great experience other than the nasal spray.

Hello Gabriel,

We are very sorry for your experience. We have contacted Poste Italiane regarding the status of your package, but we have not yet received a reply, so there is unfortunately nothing further we can do at this moment.

We can reassure you that your order was sent out on the day it was placed. However, to be completely transparent, deliveries in Italy have proven to be among the most difficult to track for reasons beyond our control.

Please rest assured that we would never scam anyone. If we determine that there is an issue with the package, we always offer either a reshipment or a refund, as many of our clients can confirm.

Please feel free to email us so we can discuss this further. :)

Great support!

My order was unfortunately confiscated by customs. The seller refunded me fully and was very helpful. Will definitely try ordering again in the future!

In general, we do not experience customs issues with other EU countries. However, Estonia—despite being part of the Schengen Area tends to have stricter customs procedures, which can occasionally affect deliveries.
In your case, it appears this was simply a matter of bad luck. The vast majority of our previous orders to Estonia (around 95%) have gone through without any issues, so this situation is not typical.
We truly hope this will not discourage you, and we would be happy to see you place another order in the future :)

Fast delivery

Fast delivery, the products work, but for example, for the much-vaunted retartrutide, I started with 4 mg and it really killed my hunger in one day, the next day I was hungry again, so this product works but you need high doses, which is still very expensive.

Good quality peptides

Its exceptional finding a peptide vendor where almost all products have 99%+ purity and lab tests are recent.
Seems legitimate. Orders are delivered without customs troubles.

Only suggestion would be to use other laboratories then just Janoshik for 3rd party testing.

for some reason not all peptides have their lab tests posted, also the batch number is missing in every test and the thing that makes no sense is that for retatrutide 10mg the lab test shows a result of 14.35mg although having more product is good, if not labeled well this is extremely dangerous for overdosing ...

Hello, we constantly do interanl testing for every batch. It's just not realistic to have full janoshik test for every batch. When it comes to the overfilling, this was an one time exception, but we will soon update the test itself for more clearance

You're claiming 99% purity with lab tests, but there's no batch number to verify it.
Without traceability, a certificate means nothing. Stop fooling people!

We fully understand that traceability and transparency are critical when it comes to laboratory testing and product quality. That’s exactly why we provide every customer with the option to independently verify our products. Any customer is welcome to send their vial to a laboratory of their choice for independent analysis. If the test result does not match the purity specification we state (≥99%), we provide a full refund — no exceptions. We stand behind our quality claims with complete confidence.

Regarding batch numbers: you are correct that some of the very first test reports did not include batch numbers. This was part of our initial testing phase. Since then, we have implemented full batch traceability. All newer test reports are now clearly linked to specific batch numbers, and every new batch is tested and documented accordingly
