Product Info
Amino acids are the chemical units or "building blocks" that make up proteins. Protein provides the structure for all living things. Next to water, protein makes up the greatest portion of our body weight.
Protein make up the muscles, ligaments, tendons, organs, glands, nails, hair and are essential for bone growth. Enzymes and hormones that catalyze and regulate all bodily processes are protein.
USN Aminos provides all the amino acids needed to support protein synthesis.

- Very goodReview by Zziwa (11 January 2022)
- It’s much more better
- AlrightReview by Ty (16 June 2020)
- This supplement is for women who can swallow big pills.
In my opinion the dosage of the aminos are too small to see significant changes.
Need at least triple of the dosage.
People be supplementing with 10 grams glutamine where you only getting 170 mgs here just not enough.
I would rather cough the money out and go for animal pak all aminos, vitamins minerals and a lot extra at high potency. - KhauoeReview by Tshepo (18 December 2019)

- badReview by faheez (12 August 2018)
- i tried it...at first it was cool..today i took 5 pills before training and this had a bad effect on me.. am feeling unwell and i could not train as i felt my head heavy as i finish a specific training..
i think this is a bit dangerous and not to take too much.. - No pain no gainReview by 50 Quadrant (18 July 2018)

- Best build and recoveryReview by Noni (29 May 2018)
- Helped me gain muscle mass. With great diet of course. I take 2 pre and post work and 2 before bed time. Taste is bad but better when mixed with whey protein.
- Dnt needReview by Sanza (10 May 2018)
- I want to feel the pain after a workout. I want to feel my gains. Not only see them.
- initially I saw my muslces getting bulkyReview by jehu (22 February 2018)
- But now it seems my muscle is getting bigger again
- I feel it worksReview by LEE (7 January 2018)
- I've been on this for a month now... Definitely helps with recovery and soreness.... Tablets almost killed me... Got stuck in my throat as it's dry and sticks... I eventually started crushing then whole and breaking them down then drinking my Pre workout... I only use them pre workout but could see results eventually.... I've always wondered why the small pimples on my arms and now I know cause I've never had acne before... Small side effect for the gain in my opinion... No cramps or any other side effect... All in all a good bang for buck product... If only they could make the pills smaller to swallow.

http://www.livestrong.com/article/172674-side-effects-of-amino-supplements/ - REMOVE THIS PRODUCT FROM THE MARKET IMMEDIATELY. Do not use this product at all !!!!Review by Ann (6 February 2017)
- My Husband has been actively involved in the Body Building and Fitness Insustry for many years, Today he landed up in the Medicross Emergency Unit in Boksburg, after taking the recommended dosage before his training. It's the 1st time he tried to use this product.
Its been 8 hrs and he is still suffering from severe abdominal pain, extreme diarrhea, and he can't stop vomiting. His blood pressure has dropped and must be monitored every few hours until he has stabilized. How can this product still be sold to the public?
Is anybody at USN going to take responsibility and remove this product from the market?????

- First time i have used a Bcaa, and could actually feel a difference. Helps create and hold a good pump, and my recovery has improved a lot... Full range of Bcaa, a pretty decent quality and not expensive for what you get.
- Good productReview by Izak (2 October 2013)
- Really helped to minimise sore muscles after an intense training session. Not a fan of the huge tablets. really struggled to get them down. Only way I could take them was by breaking them up in smaller bits and mixing it with my whey shake.
- Nit of a reaction but workedReview by asb (19 February 2013)
- Bought the 120 tab pack.Tablets a bit hard to swallow so started with 4 pre-workout.Worked as not I did not experience any post workout muscle fatigue.I do not take anything else and I got some rash and acne after using for a few times so I reduced the dosage to two tablets before workout and two after which was better and settled the acne.

- Good to keep muscle mass, but won't recommend it to a hardgainer unless u are already using a mass-gainer, but its a good product! Its a perfect recovery and muscle building supplement, but good carbohydrates is essential!

- i bought this used it seen it work but then i started to get a rash on my arms it was like a heat rash but i would recommend this product it works, but it dont agree with me
- essentialReview by johan (4 October 2011)
- huge pills, hard to swallow, however if you are serious about building you have to take these up to support your recovery. however there are vast amounts of post gym shakes that provide these amino acids... Hell at these prices you can afford to take a little extra, I am currently using, results will be posted.
- Not BadReview by watch this space (14 September 2011)
- Great to supplement with your Protein, however I got bad reaction to skin (acne) not experienced by other supplements.. did anyone have a similar reaction?
