Been using this for about 5 days and what a change! Feel so much energy in the gym and my will power has sky rocketed!! Very very good, I am only using one pill per day due the the ultra high caffeine content xx

Amazing product, have been on them since the start of January and lost over 2st with a healthy diet and exercising 4/5 days a week. For me, i only take 1 caps everyday and i can really see a difference in my performance! Definitely recommend!! Thankyou x

Have definitely noticed an improvement in losing weight since take these, only after just a week I've been seeing results, they give me lots of energy for work outs and I don't feel as hungry anymore and feel fuller quicker. Only downside is that sometimes I get stomach ache and it can keep you awake at night.

Love semtex! Only been taking them for 5 days and instantly felt heaps of energy from the first day which helps me to workout for longer than usual. Lost 6lb in 5 days by eating well, exercising and taking semtex. Would recommend to anyone and everyone!

A great product. If you use correctly, don't eat crap and expect this to do the work for you! You must exercise and sort your diet out too! This helps as you sweat like a mad beatch when working out and I find it suppresses my appetite. I find 1 is enough for me rather than 2! And if you feel lightheaded then you've not drunk enough water!

This stuff has worked really well for me, quite a good appetite suppressant and pep's me up before I go gym, I would defo recommend it.

Date Added: 01/22/2014     by Terese Blaggit Walker
Amazing! 6lb down in a week! mega happy! Only downside is not being able to sleep. Advise not to take any after 4pm, I take my last one at 2pm and still can't sleep at night but apart from that, this is an amazing product. Worth the buy :) xx

Brilliant! My workouts last more than twice what I use to do, gives you so much more energy!

I took Semtex for about a month & I think it definitely helped with the weight loss. I lost half a stone in about 4 months but I also exercised and ate healthy. Some days I feel it helped me feel energetic and motivated and other days not so much. The only bad thing is I literally couldn't sleep at night after taking these! I would recommend taking them early in the day if possible.

Date Added: 10/31/2013     by Emma Bryson
Absolutely brilliant! Only been using Semtex for a week but I can already see results. I am training harder and for longer. Brilliant energy boost and I would highly recommend!

I have bought this product in the past and is amazing, you can defiantly see and feel the difference not long after you start taking them, I did sadly stop taking them and now I will be buying some more and will be sticking to it! I am just wondering what types of foods people eat when taking these tablets? thanks xx

Great product, defo improves my work out sessions & makes me look forward to the gym!! Lol

Date Added: 08/27/2013     by Stacey Jones
Took this for a month now, as directed sometimes both tablets before workout or 1 in morning 1 in afternoon. I am thrilled with result. No side effects at all. Weight loss is much faster then it was without.I strongly recommend Semtex; in combination with sport and diet it works really well.

Amazing product, after taking this i feel the energy run through me! I feel that i can last longer and train harder in the gym when using Semtex, and so far have lost 4lbs! I couldn't recommend it enough!

Date Added: 06/24/2013     by EMILY SAHIN
What can I say about Semtex that isnt WOW! I read lots of reviews on lots of websites and decided to give them a try. I work 13 hours days and dont feel up to a work out afterwards. however, if i take Semtex about 30 min before Ileave work I feel i could run a marathon. Excellent product - Cant wait to buy it again. ONLY BAD THING is that I dont have caffiene in my diet so on the 1st day when I took two, I had a fluttery heart and my hands were shaking. Since then I have stuck to one and have been fine :) LOVE THIS PRODUCT

Date Added: 06/20/2013     by Vicky Stanton
I spent months reading the reviews before I decided to buy any Semtex, and every single one of them was positive, so I took the leap and got some. On day 1 of taking them, I weighed 120kg (18stone 9lbs) and 4 weeks later I now weigh 110kg (17stone 3lbs). I am so so impressed and happy with these that I am converted for life!

I have been taking Semtex combined with Hebex for 2 weeks now, along with a clean diet and daily exercise, I am over the moon with the results! Toned skin, reduced stretch marks, and already lost 7lbs. So excited to find a product that works, highly recommended! The only down side is that the pills are quite large to swallow!! :) I will keep up with taking these and I am going to look into start using Neptox after hearing great things :)

Hey all amazing delivery and i love the extra energy gained from semtex

Date Added: 06/06/2013     by sarah tongue
7 weeks ago I was 1 1st 4lbs. I now weigh 9st 13lbs. It has been a consistent loss, maintained by gym, power hoop, squats, decent diet and determination. I had never been able to lose more than a few pounds and then gain it back again. Something clicked in my head and Semtex has really aided it. I can feel it working and it makes m more determined. The semtex community is fantastic and supportive. Just click add to cart!

Bought this the other day and delivery was so quick! So please as I have lost 5 lbs already from taking them Tues-Thurs. That is with exercise and a healthy diet. Only thing I would suggest is not to take them later on in the day. I took them at 5pm before the gym. And couldn't sleep that night. Thats the only thing really x

Date Added: 05/23/2013     by carly urwin
Wow!! the product is amazing - twenty minutes after taking it I can feel the buzz and the urge to train train train - and I am able to do push further with cardio and weight training. go for longer, feel fitter and feel stronger. It really works!!

Actually works and helps me lose more weight than usually, however massive headache during workout due to the high amount of caffeine and didn't feel that much more energized. Although this product isn't that expensive and I would recommend for weight loss

Since taking semtex I've lost 8 plbs, still got quite a lot to lose so ordered some more. Noticed that when I miss a day I feel tired. Even though I've lost over half a stone I don't actually feel it or see it on myself but going to keep it up and hope to get the results I'm after for summer. Oh and no side effects at all

I have nearly finished my 1st lot and just ordered another lot. I don't have much to lose and at my weight loss class I have been struggling. I bought these and I have lost 8lbs. that may not seem much to some but I am a slow looser and I don't have much left to lose and this is a massive amount for me! could never have done it without semtex and couldn't be happier, fab product!!!

Date Added: 01/17/2013     by Tammy Wright
So far so good. Been taking these nearly a week now, and lost lbs that I wouldn't have shifted normally. It's made me feel a bit like I have a gastric band! Not hungry at all really, try forcing food in at meal times but can hardly eat anything. Suffered no side affects as yet, apart from went a bit shaky and clammy when I took the first 2. Also found I can do a bit more than normal at the gym, but I don't know if that's in my head or the actual semtex!

Date Added: 01/14/2013     by Sarah oldfield
Amazing! been using this for a week- usually feel tired every day and struggle to walk without wanting to sit down, but in the week that I have been on it I have felt so good, full on energy and motivated to do anything! I have lost 6lbs with a fairly good diet- been eating under 1500cal a day, and I have only exercised a few times. If I manage to lose the same amount in this next week then that will be almost a stone lost in 2 weeks with the help of semtex!

Date Added: 01/12/2013     by Jessica Howard
Sounds great!!! Just ordered my 1st lot. Cant wait to start taking and watching the weight come off! I'm 15 stone 9lbs and a size 18. I have until April to get to a size 10!! Fingers crossed.

Very good for curbing appetite and giving energy boost and I have lost weight, the only downside for me is that I get really bad spots. I don't normally get spots either.

I was amazed to finally find a product that actually works! I ordered this a week before my 19th birthday and was hitting the gym as usual but it gave me so much more energy! I weighed myself the night before my birthday and was so ecstatic that I had lost half a stone. I know go to boxercise classes as well as the gym, something I never thought I would have the energy to do and I can't weight to weigh myself again at the end of the month. x
