MASI Longevity Science Avaliações 

Third party testing. Independent reviews backing up statements and claims of purity. Service. Ships on time. Arrives on time. This in spite of torturous journey from manufacture to third party testing to customer.
Five stars!

I cannot assess the real benefit vs. price. Moreover, as I also have to take other substances ( selenium, zinc, magnesium, Vitamin B and D3) to support my tyroid, I fear that I take these substances twice.

FedEx dumped my order in the driveway where my dogs were. I lost half my order since they opened the box and ate 2 bags. Fedex failed to put my order in the designated box as always done in the

One of the best products on the market. Also, most importantly when you place an order that arrives in a timely manner. My opinion, this product is top tier with great Customer service.

The product is great, but I've had to cut back my budget and can't afford the subscription any more. I've tried multiple times to cancel my subscription but once I hit the button to cancel it just spins and never cancels. I'd give it more stars but I'm frustrated.

Product is great, but took months to arrive if it even cleared customs at all I got a call from FedEx telling me * have to sign special customs forms to clear it for delivery? No thanks

I mistakenly took two in the morning and two at night 😳 for the summer my blood work in the fall was lower sugar better cholesterol and my eye sight was improved . I am now taking the proper amount one morning and one at night but hmmmmmm

Excelente producto

Good products. Both me and my husband have been on the MASI regimen and we are not going back to living without them.

MASI should improve their shipping times but it's not a dealbreaker for the quality that you are getting.

All the products are great, thoroughly researched and tested, and always arrive on time!

Good Ad, tested elsewhere!

Muy buenos productos. Desde que me los he empezado a tomar he notado cambios directamente.

Fantastic!!!! I feel alive again, nmn has changed my life. Been on MASI nmn for the past 3 months, I've been struggling with anxiety for over 10 years and this supplement is the best thing I've ever added to my routine. It took about a month to TRULY kick in but once it did my I was finally able to sustain conversations without rising anxiety regularly! Love everything about this brand!!!

Wow! Absolutely amazing Spermidine from MASI EU is top quality. I've taken it now for a month, the supplement overdelivered above my expectations, I was not expecting skin smoothness so fast! I first bought it after watching a clip online about spermidine cleaning your cells and now I can see the effects.

I would give zero. I had bought the gift for my wife expecting her to enjoy as it was already second by without any visibal effet, but believing that maybe after some tim ether will be some positive effect. When she opened the box, carton inside was crubled, as if someone had already opened the box before her. After few days of trying to use it she told me taht I feeel very bad like usežing someone had used it already. I have photos beu I do not have time tio waste, I was planning to buy for her more things from Masi, but after this experience it's absolutelly disappointing

It is my recommendation that anybody over 40 years of age starts supplementing with NMN, it has been proven to boost the NAD molecule which is responsible for all energy production in our body. This is something that naturally declines with age so supplementing with its pre cursor which is NMN works to lower your biological age in return. You can still get younger as you get older and that's fascinating. Great efforts from MASI brand, highest quality I've tested.

Good product that makes you feel alive again, effects last all day

Its great. I've been taking NMN for multiple years, with many different suppliers and MASI has been my go-to for the past 6 months. The dosages are high but most important are the batch results, with so much fake NMN it's hard to know exactly what you're getting, this brand eliminates that. Hands down the best NMN on the market!

Unfortunately, I'm not receiving any replies to my messages. The packaging is indeed very nice, with the same number of layers as expensive creams. I think this is completely unnecessary for tablets and generates a lot of waste. I wrote to ask if they have an alternative option for those who don't want to produce unnecessary waste, but no one responded. The same thing happened with orders. I placed two orders and they were being shipped simultaneously. I sent an inquiry about combining orders, but I didn't receive a response. Besides, my first order was delayed by almost two months. Only reporting this and threatening to cancel the order had any effect.
