STACK

My first time in the realm of supplements I’ve been on a bit of health kick and lost 4 stone through weight training , low impact cardio on cross trainer and super clean diet , I’m 59 and wanted to improve my physique and was recommended SD Matrix from a work colleague who has been into power lifting and body building his whole life , so I took the plunge and ordered up SD Matrix and added it to my morning and evening supplement routine , after a couple of weeks I hadn’t noticed anything and being impatient I had a chat with Stef and asked him if I could boost my progression, so after this I added LGD4033 as a stack on top of SD Matrix and another week went by and I thought it’s all bs 😂 but OMG was I pleasantly surprised as I had some very noticeable skin tight pump and looking quite ripped across my shoulders and arms , if I’m honest I’ve not had any improvement strength wise but I think my test is none existent as I’m an older dude so will be looking into trying to get that sorted and hopefully strength will improve once I’m sorted , so guess my take on it all is be patient and give it time and keep on top of your diet and training and you will definitely notice more definition. It’s definitely not snake oil and the SD Matrix & LGD4033 stack is highly recommend

An honest review of SD Matrix…

This is an honest review of SD Matrix Black.

I didn't feel anything for the first 2 weeks. But during the 3rd and 4th weeks I ve gained 11 lbs of muscle while losing a significant amount of fat. Also my strength levels were through the roof. Also you get this insane pump throughout the day. It just doesn't go away.

Sides

Lethargy. Sleepy throughout the day.
Appetite suppression. I dont get hungry at all and found it super difficult to eat.

Luckily all these sides left once I was done with the cycle. I ve lost almost all of the muscle and strength gains I ve made but my test levels weren't suppressed much and returned back to normal soon. I am on the last day of my PCT and feel normal.

As far as the product goes it definitely works but takes time so be patient. And lastly Stef is amazing. Always ready to help.

Hey Norris, as you can see in the tracking information we shipped your order immediately on 4th July. We ship it 'Royal Mail Tracked 48' which means Royal Mail should normally deliver it within 2-3 days (you can check this on the tracking information provided). However, we did notice indeed that it took them a bit longer to actually deliver the items; luckily this is unusual. As you know from your multiple previous orders we always try to deliver as soon as possible. Furthermore, because of the same reason, we assume you're actually very pleased with the products themselves?

SD Matrix Supplement Review

SD Matrix Supplement Review

I’ve been using SD Matrix for a while now, and the results have been nothing short of impressive. From the very first cycle, I noticed a significant increase in muscle fullness and an incredible pump during my workouts. My overall strength has improved noticeably, allowing me to push through heavier lifts and more intense sessions with ease.

One of the most unexpected but welcome changes was the positive shift in my mental state. Seeing and feeling the results firsthand gave me a massive confidence boost and kept me motivated to stay consistent in my training.

The customer service from SD Matrix has been top-notch as well. Shipping is always fast and reliable, and communication with the team has been excellent. Any questions or concerns I had were addressed promptly and professionally.

If you’re serious about your fitness goals and looking for a supplement that delivers both physical and mental benefits, SD Matrix is definitely worth considering.

Hello Rodney, thanks for your review.
We noticed that your ordered from us on 7 September of which you received an email confirmation immediately after your order. We shipped your product - with a delay - on the 15th of September. You received an email of this with tracking details from Royal Mail. The reason for the delay was that the product was temporarily out of stock. You can see on the official website of Royal Mail that your order is currently being handled by Royal Mail. It doesn't mention anything about being in transit which also doesn't make sense since your order is for the UK (and we ship from the UK) so I'm not sure where you got this information but I'm afraid it's incorrect. Please only rely on the official information from Royal Mail. So, we're happy to admit that not everything went well with the delivery so far and we sincerely apologies for this and accept your complaint in this respect. However, we would appreciate that you are also honest in your review and mentioning that we would use fake tracking numbers is not a correct statement. Kind regards, Stef

Midway through my first cycle, noticing better moods which is helping me stay more focused on my training, not had much gains in strength but still early days on my first cycle, had no side effects so overall happy with how it's going look forward to seeing if I notice any changes after the end of my cycle

Hello Leon, we did indeed have issues with one specific product - T Matrix Testo Booster - that went out of stock unexpected. Once it became clear that it wouldn't come back into stock soon, we sent you an email to notify you and to give you the option to get a partial refund (for the T Matrix Testo Booster) or to cancel your order (with a full refund). As you can see from the other reviews, we always try to give a good customer service and experience but we understand this was not what you expected. Regards, Stef

Been taking lgd4033 for three weeks and the results are great. Loosing fat and gaining muscle. Not bad for being 56yrs old. I would highly recommend for fast results.
