Good — I found info about Legend Labs Beta-Alanine (or “Legend Lab / Legend Labs Beta-Alanine”) for you. Here’s what I learned.

What is Legend Labs Beta-Alanine?
Legend Labs Beta-Alanine is a powder supplement whose active ingredient is beta-alanine, an amino acid used to support performance.
The listing I saw describes a package size of ~180 g with ≈ 60 servings.
The supplement is intended to raise muscle carnosine levels (via beta-alanine), which helps buffer acid buildup during intense exercise and thus delay muscle fatigue.
Beta-alanine helps muscles produce Carnosine, which acts as a “buffer” against acid buildup (like lactic acid) in muscles during intense exercise. This buffering helps delay fatigue and burning, allowing for longer or more intense training sessions.
As a result, users of Beta-Alanine (including Legend Labs’ version) may experience improved endurance, ability to do more reps/sets, or sustain high-intensity workouts longer.
For athletes, body-builders, or people training with strength/resistance or high-intensity workouts — Beta-Alanine is often considered one of the “go-to” amino-acid supplements for performance.
Legend Labs Beta-Alanine comes as a powder: typical use is mixing a scoop with water or drink before training (or as indicated on the product label) for performance support.
Benefits tend to accumulate over time — because carnosine levels in muscles build up gradually, so consistent supplementation over weeks is often recommended.
The main intended effect: delaying muscle fatigue / improving endurance / enhancing training output — especially useful in high-intensity or strength training settings.
A well-known side effect for many beta-alanine supplements: a tingling / “pins-and-needles” sensation (also called paresthesia). This is typically harmless, but some people find it uncomfortable.
Beta-alanine is not a magic solution — benefits depend a lot on your overall diet, training, rest, and consistency. It complements a good fitness plan, but doesn’t replace hard work or proper nutrition.
As with any supplement: if you have medical conditions, or are unsure — it’s wise to consult a professional before using regularly.
Legend Labs Beta-Alanine seems to follow standard beta-alanine supplement format: reasonable serving size, correct ingredient, and the intended benefits line up with what research and user experience suggest.
It’s a reasonable choice if you:
Do regular intensive workouts (strength training, HIIT, CrossFit, heavy lifting),
Want to delay muscle fatigue and improve endurance,
Are willing to use consistently over time (not just occasionally),
Understand that supplements are just one part of a fitness plan (training + nutrition + rest).
