  • The correct ratios of ingredients meaning they work in synergy and don't cancel each other out
  • A must for anyone taking anabolics, Testosterone boosters or anyone worried about the effects of excess estrogen

Not many sports nutrition companies have the high-tech manufacturing capabilities of LA Muscle laboratories. This is why you only get supplements like Estro Star from LA Muscle. Many men also have very high levels of Estrogen these days that they don't know about - and this is a major reason why they don't build muscles mass. Lots of things such as plastic and estrogen in the water are contributing to these high levels of estrogen.

Make sure you take this supplement alongside your Testosterone boosters for the very best results. Even if you are not taking Testosterone boosters, you will still benefit from Estro Star especially if you live in the Western World, which is polluted by plastic and estrogen in the water.

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.


Please note that LA Muscle cannot guarantee its products from being free of certain allergens. If you have a severe allergy to any ingredient including milk, soya, nuts, fruit or anything else that can cause you a life-threatening condition, we strongly advise you NOT to take LA Muscle supplements (or any supplements for that matter). If you are not sure or suspect an allergy, please see your doctor immediately.
