Optimum Nutrition ON Gold Standard Pre-Workout Advanced with l-Citrulline, Beta-Alanine and Caffeine, Blue Raspberry, 20 Servings, 420 g

6ft 16 stone 10-15% bodyfat. After 10 years (of near consistent as allows) 7 days a week gym use and using almost every pre workout you can name from cheap to very expensive this is definitely up there in my top 3 if not the best I have ever tried, but do try with caution as it is very powerful and read on for my usage. Today I did my first ever in 10 years 2 x 2 hours intense weight lifting in an 8 hour period with 15mins cardio in each (Supersets with minimal break) no sitting on phone etc, 30 seconds on, 20 seconds off, jumping from machine to machine, sweat dripping everywhere, sets until faure, heart rate 100-150 constantly, veins popping out, felt like the hulk, everyone looking at me like "what the **** is he taking" crawled out the gym to my car. usage: I use the full 3 scoops per 2 hour workout mixed into a FULL lucosade 900ml bottle filled with water. I do not like itching so I drink 1/4 soon as get the gym / on the way while on the way then top the water back up to full to dilute, then drink another 1/3 slowly while working out then fill to top to dilute again. By now its really kicking in but take it easy to avoid itching, keep drinking and diluting 50% per 10-15mins and you'll have no itching and be on fire for 2 hours solid and come out the gym like wow that was insane. Can't rate it enough, they have put alot of research into this product and it tells. Reminds me of product I used before about 9 years ago but ended up diluted over time to save cost, if this product stays the same forever I'll never change other than the flavour. Thank you for transforming my workouts!!

Beta alanine is possibly a bit too high for my tastes - it feels like ants in pants. Also idk what they’ve put in it compared to the other stuff but 200mg caffeine in three scoops vs 175mg in one scoop seems like you’re consuming more bulking agents to me. Taste is not there compared to the other stuff they make either. Four stars because it still gets you going in the gym

When they say advanced they mean it. If you're used to regular gold standard or other pre workouts try 1 or 2 scoops first and DO NOT BE A HERO with the recommended 3 scoops. I genuinely feel like a 2/3 scoop of this is more intense than a double dose of some others I've used. Everyone who I've given some to try has told me that night was sleepless and the workout was intense and focused, and I agree. This let's you push harder than you thought, and the pump is crazy. I recommend if you are used to your regular scoop and feel like you're up to it. Stay hydrated. The taste however, it's safe to say that I won't be tempted to sip on this for the flavour. If the energy it puts into you had a taste, it's this. This tastes like a lightning strike and not in a good way, but the results are worth pushing through it and drinking it fast, if you're at this stage of buying advanced/expensive pre workouts you're probably more than used to bad tasting supplements anyway, but if flavour matters to you, this really is not the one for you.

Great product and the taste of the blue raspberry is lovely, product arrived well packaged and sealed, so far I would say it's a very effective product and I have had no side effects, definitely found my brand and will continue to purchase them as the boost to energy and quality ingredients, just make sure you read the description correctly as it had a high strength of caffeine

This has a very artificial taste and colour ,not for me im afraid!

Worst taste like a medicins, no doubt it have a good results but the taste is hateful. Never going to buy this flavour , raseberry.

I think by the time you get halfway through the tub your body will become too used to the caffeine dose to feel a kick, (I use 4x a week and don't have caffeine anywhere else in my diet) but I do feel it can help sometimes when I am exhausted from work and need to play a match or workout. There is a fishy smell that sometimes comes when I use it or at least in the container so this can be off putting but the taste is fine and easy to shot.

Plenty of kick for proper workout. Tastes good Mixes well
