This incredible supplement contains THE BEST 3 muscle building and recovery amino acids in the perfect ratios meaning guaranteed noticeable results in strength, muscle recovery and muscle building.

Amino acids for muscle mass and speedy recovery

Branch Chain Amino Acids are scientifically proven to reduce muscle damage as a result of exercise (1). LA Muscle Branch Chain Amino Acids 311 BCAAs contain the 3 most important amino acids for muscle building and muscle recovery. 311 BCAAs contain Leucine, Isoleucine and Valine in the exact ratios as shown in scientific studies to build muscle recovery.

BCAAs taken in any other ratio other than 3-1-1, will not work to aid recovery or build muscle. You may get other Branch Chain Amino Acid formulas which have just thrown in amino acids for good measure. Only the 3-1-1 ratio has proven to dramatically aid muscle recovery and muscle growth. This ratio stimulates increased protein synthesis meaning you are not at risk of muscle breakdown (catabolism), which can often happen especially when dieting and calories are restricted.

Optimal times to take LA Muscle's 311 BCAAs are in-between meals and intra-workout. LA Muscle guarantees noticeable and fast results from this scientific formula. This is THE BCAA FORMULA for guaranteed results.

Recent research heavily favours the benefits of leucine supplementation between meals (leucine pulsing). This dramatically increases protein synthesis and leads to muscle growth.

Supplements not medicines
LA Muscle supplements are "Nutritional Supplements". They are not medicines or drugs. They do not prevent, diagnose, restore, correct or modify any physiological condition or function in human beings. They will not treat diseases; they are not medicines. If you have a medical condition, please refer to your physician. If you get "any" side effects at all, stop use and refer to your doctor immediately. Never take more than the recommended dosage. Male hormone boosters are for people over 18 and mature for their age. If in doubt about anything at all, please contact LA Muscle.

LA Muscle Tubs

In line with LA Muscle’s Green Policy and reducing carbon footprint, LA Muscle is using a “ONE SIZE” tub for most supplements. This is to reduce the use of plastic tubs by having tens of different sizes for various products and having to over-manufacture plastics. As a result, you may find that in many LA Muscle supplements, the tub is much bigger than the total size of all pills. You are still getting the exact number of pills/capsules/powder you have paid for, however there will be extra space at the top, giving the impression to some people that the tub is not full. This is solely because of our commitment to reducing the need for making extra plastic tubs. LA Muscle does not use cotton wool to fill up the extra space because cotton wool can attract microbes. Your safety AND the protection of the planet are big parts of the LA Muscle ethos.

COVID Impact
Please note as a result of the pandemic, some products may come in different packaging than what is advertised. This is due to a global shortage of tubs and lids. LA Muscle manufactures worldwide and has made a conscious decision to use alternative packaging where necessary in order to avoid running out of stock. So for example, instead of a black LA Whey Tub, you may receive a gold tub.
