Optimum Nutrition Gold Standard Pre-Workout Energy Shot, Ready to Drink Food Supplement with Beta Alanine, Caffeine, PerforMelon Boost and Vitamin B6 and B12, Mixed Berry Flavour, 12-Pack, 12 x 60 ml

"Is it effective if you lack energy or before a workout? The taste is nice and I don't have any side effects, but I consume a lot of coffee, so maybe that's why I'm okay. However, my husband, who doesn't drink coffee, experiences side effects from using these shots. He feels sick and sweats. Be careful when consuming it."

I've tried a number of pre work out options, from powders, caffeine chews, monster drinks etc. These are by far the best option I've come across personally. A little on the synthetic side taste wise but give you a great boost pre workout, don't mess my stomach up or give me the jitters. I'd even go as far as to say I feel stronger!

Gives a wee buzz for a workout! Tingling fingers & face- I don’t take caffeine so it certainly gives me a wee get up n go I got cherry 🍒 and the lime - I preferred the cherry flavour xExUpdate!!! I had to stop drinking these I developed heart burn 🔥 (I have never had before and after a few tests with/without drink, I have reliably identified these as the culprit (the lime one gave more severe symptoms) sadly they are no longer for me! 🔥🔥🔥🔥xEx🔥🔥🔥🔥🔥

While there are undoubtedly stronger or perhaps better pre-workouts available for the serious gym-goer. These are more than up to the task of giving you a bit of energy and motivation to get to the gym and do your workout and sustain you while working out.You can feel the skin tingles kick in about 20mins after drinking and there seems to be no crash afterwards, just a nice pleasant energy boost. I like the nice "shot size" as it means it can stay in my bag and i never forget to have one before heading to the gym.

I initially found these quite sour the first few I had but realised they work great and quickly got used to the flavour soon after. My morning routine is to run between 5-10km before work and I take one of these shots 20-25 mins before I start. Considering I am finishing upto a 10k run by 8am I’d say they do the trick! I do get a tingly/itchy sensation in my face and hands about 10-15 mins after I take the shot but it doesn’t last too long and it’s not too severe. Certainly worth having one of these than not. I have tried a couple other pre work out shots from the gym vending machines but this is still my preferred brand and flavour and get this on subscribe and save.

The taste of this makes it hard to swallow, like it's some medicine, too chemical. If I didn't know what it is, I would've thought it's some washing up liquid... Anyway, performance is what matters in the end, so after a few minutes of taking it, you can feel some tingling to the face, ears, hands etc., but this fades in like 20-30 min. The energysing effect for me is very random, sometimes it gives me enough energy to have a fast 30 min workout, other times it's useless for a workout, it may only wake you up when tired or sleepy. Nevertheless, this proved to be stronger than ON pre-workout in powder form.

Tasty, got a nice zing to it!

This is exactly what you want from a pre-workout. I drink a fair bit of coffee on normal days, but none when I drink this in the morning before workouts. I wouldn't use it for anything other than intense hour plus training. Makes my face and ears tingle and feel very buzzed for several hours. Great quality, tastes good.
