Brilliant product but big delivery issues

Great product and good company to deal with. I have been having big problems with delivery. I ordered Invictimune about 6 weeks ago and this Lemello order 21 days ago but neither have arrived. I believe it might be a local post issue, there seems to be something up with the supply issue.
I am giving 5 star review as I love products and company but delivery issues need to be resolved,

Don’t quite understand this put a bunch of herbs in there to energize it and then put a lack of caffeine in there. I guess it rocks some people boats

Express delivery

I ordered with express delivery, three weeks later and I still have not received the package. No update from Zenstra after contacting them multiple times. Very disappointed with the level of service as I bought from Zenstra many times before...

Unfortunately we have requested our order to be send by DHL but instead it was send by Royal Mail and this resulted that package went through Cyprus customs and is still held there for examination.

Zenergise - First Impressions

I've been using this product for around a month now and I've been really impressed. I'd been suffering brainfog, lethargy and a general loss of joie de vivre due to either a bad cold or Covid. This product has me back on point again; even colleagues have commented that I have more energy and focus and the communications I've issued have illicited several compliments. Based on this experience, I can see me being a repeat customer.

Jury’s still out on these

I will be honest, these are not proving to be as significant as ZEN1 or Lemello. My insomnia has become worse, but it’s unclear as to whether that’s directly attributed to Zenergise or not. I will be happy to review again in 6 weeks time

Taking the edge off.

When things get tricky these really help take the edge off things and make life not seem quite so serious. Don’t have any expectations of feeling anything or getting a mellow hit, I didn’t get those, but just an erosion of serious things. They’ve helped with sleep too, but I usually have them in the day and then don’t tend to need them in the evening.

Never Received Item

Purchased item several weeks ago, item was returned to sender by DHL, DHL say contact seller. seller customer service email bounces back, very disappointing because order regularly on this site and the products are genuine really good

Hi Raymond, we are terribly sorry about the issue with DHL. The EU recently changed customs labelling requirements and our UK fulfillment centre was unaware of the new changes. We have updated our package labelling and your order has been reshipped. We are so sorry once again Raymond.

My favourite supplement 5*

These supplements have massively improved my wellbeing through times that I have felt stressful. They massively help with brain fog, allowing me to get through the day with much more energy and an overall more optimistic view on life. I can’t thank the team at Zenstra enough for these life changing supplements

Amazing

Taking both zen1 and zenergize provided me with excellent concentration and focus throughout completing my degree. I feel sharp and clear without feeling jittery, and even improve my outlook on life, giving me a boost of serotonin whenever I need it.

Best night sleep

5* product that helps me calm within an hour and provides me with the best nights sleep whenever I am stressed. Cannot recommend these enough if you struggle with anxiety or stress.

Amazing supplement

A brilliant supplement that has been designed with evident in-depth scientific research. Full of fantastic ingredients that you do not get in other supplements. I take these any time I feel under the weather and within a few days I’m back to full health
