Great product!

I've been drinking it recently, as a booster 2 hours after taking collagen, usually late at night, before bed. I combine it with other amino acids, but it's very, very bitter. Just to keep in mind, in order to be able to swallow it somehow, I add a few drops of vinegar or lemon juice to neutralize the bitter taste at least a little. However, I personally have very good results from it.

Great muscle gainer but beware the taste

L-Leucine works great for me to boost muscle gains. Makes training progress very satisfying. Another great benefit, price per dose is very cheap. Make sure you take this one strictly right after work out and strictly on days you have workouts for best results and optimal longevity impact. Biggest downside is taste. I tried different brands, they all have terrible taste. I drink it separately mixed with water like vodka shot. Nothing seems to be able to hide this taste.

Nutricost, L-Leucine, Unflavored, 17.9 oz (500 g)

I purchased this L-Leucine powder for its role in muscle protein synthesis, a key benefit for anyone serious about fitness. The quality is excellent, and as an unflavored powder, it mixes perfectly into my shakes without altering the taste. I appreciate that it dissolves so well, leaving no clumps or residue. The large bag is a great value, and it has an adequate expiry date, which is great for a product I use daily. I really like this product for its high quality and effectiveness.

I hate protein shake, diary or red meat. So my diet lacks this amino acid which seems to be working when supplementing it.

Very great benifit

Cheapest lucine on the market with trustable source and creditable lab test. You can mix it in your protein shake or with creatine or rub it on your medium rare ribeye after it is grilled. The quality is very great, properly sealed and no clump or wet moist. Ingredient contain L-Leucine at 500g per bottle.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!

I’ve been using this Black Maca supplement for a few days now and I’m genuinely impressed. The quality of the ingredients feels premium, and the package arrived in great condition. I noticed a real improvement in my energy levels and mental clarity. It’s definitely adaptogenic, helping with my stress and focus throughout the day. I also like the taste—neutral and easy to swallow with no aftertaste. The benefits seem to be cumulative; I’m feeling more balanced, and I believe it’s positively supporting my blood pressure and overall fiber intake. Great size for a 90-capsule bottle, and I appreciate that it includes amino acids and antioxidants. Highly recommend for those seeking a natural benefit to boost daily performance!
