I cannot assess the real benefit vs

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.

Resposta da MASI Longevity Science

Here is a professional and reassuring reply:

Thank you for sharing your concerns. We understand that it can be difficult to assess the value when several supplements are taken at the same time. Clinical research suggests that at least three months of consistent use may be needed before the potential benefits can be properly evaluated.

To avoid taking overlapping nutrients, we recommend comparing the ingredient amounts on each product label and discussing your full supplement routine with your doctor, especially when supporting a thyroid condition.

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

Resposta da MASI Longevity Science

We’re very sorry this happened. Your order should have been left in the designated delivery box, not in the driveway. Please contact us at info@masi.eu with your order number so we can investigate this with FedEx and find a solution for the damaged items.

As your dogs may have consumed some of the supplements, please contact your veterinarian as soon as possible and share the product names and estimated amounts they may have eaten.

The product is great, but.....

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.

Thank you for your feedback. We’re glad to hear that you liked the product, but we’re very sorry about the delivery and customs experience.

Your case was resolved and the order was fully refunded. MASI prepays applicable taxes and duties and works closely with FedEx and US Customs, but unfortunately, customs may still occasionally request additional documentation from the recipient. We understand how frustrating this was and sincerely apologize for the inconvenience.

Thank you for sharing your experience! We’re delighted to hear about the improvements in your blood sugar, cholesterol, and eyesight. Those are wonderful results.

Please continue with the recommended dosage of one capsule in the morning and one in the evening. Many customers also combine NMN with Resveratrol as part of their longevity routine, as NMN supports cellular energy while Resveratrol provides additional antioxidant and healthy-aging support.

We truly appreciate your trust in MASI!

Loving it!!!!

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.

Fantastic!!!

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!

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 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

A real Supplement

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.

Best NMN on the market

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!

I love NMN

I love NMN, been taking it for 3 months now and its been amazing! The energy I get is truly caffeine level, but it's different. Rather than a bump its an equal line of energy throughout the day that feels more natural. I'm a complete fan, it eliminated my brain fog, balanced out my day routine due to more energy, and the packaging makes it all feel premium. An incredible supplement for anyone feeling the energy related effects of aging.

Inefficient logistics and excessive packaging production – lack of response to reported issues

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.
