The worst service I’ve ever seen

The worst service I’ve ever seen. 1 day before I sent e-mail to check availability of one product. Next because I didn’t receive answer I contacted them by messenger. Normal message - hello I sent mail, don’t have answer so my question is… reply was really polite - are you think someone waiting for your mails? 😂
In my opinion yes - not only mails from me but for every potential customer. After this message - they wrote - “ We dont sell you anythink mate 😉 try this sh..t to another eShop 😇”

So don’t buy supplements from them. If they treat people in that way, I don’t want to know how much they are “polite” when real problem with order appear.

Fantastic costumer service

Fantastic costumer service. My order was shown as delivered, but it hadn't. I emailed MonsterKing and they responded straight away. The issue was with the delivery service company. Rectified straight away.

Be careful — they delete negative reviews on the products they sell.

I bought Hammer Labz SLU-PP-332 peptide from this store. The shipping from Slovakia to Spain cost €15 and it arrived in about a week.
Unfortunately, the supplement didn’t work for me. After buying it, I learned that peptide capsules are generally unlikely to be effective because peptides can be broken down in the digestive system. My mistake for not researching more beforehand, but I’m still very disappointed — in my opinion, this product shouldn’t be sold in this form.
I posted the product review on the seller’s website, and shortly afterward it was removed. I understand it’s my responsibility to research a product before purchasing, but if a seller deletes negative reviews, something isn’t right. I won’t be purchasing from them again.

I bought the Holy Grail TB 500 peptide

I bought the Holy Grail TB 500 peptide. The oral peptide isn't absorbed. Wasted money, all marketing.

… This isn't fake news. The peptide has arrived, but if you look into it more closely, scientific literature shows that TB 500 is destroyed in the stomach by gastric juices and isn't absorbed, so it's a waste of money.

Legit Insane Labz and Centurion labz products

I live in Italy and i was searching for some supplements to sleep (Insane Labz Nightmare, %5 nutrition Knock off, and others). I also bought God of Rage Unchained from Centurion Labz as i was running low on my actual tub. All products are legit and shipping was very fast. I really want to try also the Dark Labs products, but i have second doubts as on their Instagram Page Dark Labs claimed that all products that are present on European sites are fakes… don’t know what to think, so i would like a short feedback if possible. Anyways, super experience, will buy more.

Fake SARMs

I bought multiple SARMs from this site. I’m 100% sure that it was the right site. First I bought two times Dianabol, took it 3 times daily and no results, no side effects, nothing. I did gained some muscle but because of me constantly training and not this fake products. After that I bought Test Restore just in case if I had low testosterone production. But I had not. T Restore should boost your natural T but I did not feel anything. So that was the second scam. And then the last one that confirms everything. After all of that I bought S-23 which is on another level of SARMs. IT WAS DESIGNED TO SHUT DOWN YOUR NATURAL TESTOSTERONE. PURPOSE OF THIS SARM IS TO ACT AS MALE HORMONAL CONTRACEPTIVE, except that it should act as mild anabolics. I have took it 3 times daily for 6 weeks. Did it gave me any results, side effects or forced shut down? IT DID NOT!

Update on monsterking reply:
Woow you did some research on me but Im not an Slovak athlete. He just have a same name and is long distance family i think.

First of all, yes I claim that YOUR products did not help me and I was careful for the right time and sequence of taking them.

Second of all, your reply did not cover the legitimacy of products and proofs. Instead you started to talk about PCT and not the main reason S-23. You backfired me with not taking blood and urine tests on TST, I understand that but why don't YOU take LAB TEST on S-23? You are the owner of this big company (if not move this reply to higher-ups), you need to show people that your products are real with legit paperwork and not reply to reviews like a coward. I want lab test on S-23 within 2 months (think this should be enough). If not than than this should b enough for people to see the truth. I sent you email so you can send me lab test.

And for last of all, I'm not presenting you with delusions. And your reply was awfully childish. Instead of solving this problem with calm temper and proofs of legitimacy of products, you replied with not even solid reply that did not covered the main reason of my complaint. If you would ask, why don't I do lab test, that is because you are the seller claiming that products are legit and I was paying for those products.

Warning!! We have the first Slovak athlete in the world who gained muscle from training and not from special nutrition and diet!! This is called a Slovak expert!! Only a great expert can claim such "wisdom". He claims that a pH-based product did not help him, as well as SARMs and PCT.
For those who do not have a pH product, it is food for thought. With the right time sequence and sequence, every ph works 100%!
SARMs is a different chapter, if you have a messed up hormonal system, your kidneys and liver do not work properly, then even sarms may not work properly in your dysfunctional body.
PCT that really increases TST in the body. He supported his claims without blood tests or blood and urine analyses, and then he is going to present us with such "fantastic" claims that are based on delusions and nothing more.
Still can choose roids and use this underground products!

Update after SCAMER asnwer: He wrote up - I bought multiple SARMs from this site - this is SCAM!! Just buy only S-23 notning else!!
SCAMER wrote - First I bought two times Dianabol - this is wrong info!! He bought juts one Dianabol!!
S-23 buy one bottle 60cps, he wrote used 3 capsules this is only for 20 days not 6 weeks!! This is SCAM too!!
For other customers as you can see this is SCAMER!!
On email HE wrote us they want lab test, but it´s very simply if someone wants LAB TEST just write producents, they always have this info for customers. We are just seller, not producent.
"If you would ask, why don't I do lab test, that is because you are the seller claiming that products are legit and I was paying for those products." - We don´t claim anythink!! Claim only producents not sellers, so this is just misleading information!
