Putting on lean muscle mass should always be considered a reasonably slow process with pre-cautionary safety measures already in place. If someone has experience in gaining muscle through natural resistance training (inclusive of calisthenics, plyometrics, etc.), and has never taken supplements for the purpose of gaining muscle, then it might be easy to say "start with protein powder" in addition to your vitamin and mineral supplement(s) and leave it at that. But this misses the point - what is really needed is a combination of natural substances that allow the body to better partition and reconstruct stored macro-nutrients derived from one's existing food intake. In other words, before protein powder is added, optimizing the body's ability to partition nutrients from food should be the primary objective.
Once this is completed, then macro-nutrient sources can be adjusted upward through the addition of more proteins (consuming whey protein isolate or protein serum), within the current eating pattern - but only after repartitioning (possibly through the use of insulin-mimickers) activity is commenced. In repartitioning, one creates a combined stack of substances and ingests usually one unit of each individual substance or product within the stack, during meals 2 to 3 times per day. Body recomposition effects where fat loss occurs, while lean muscle mass arises usually result. This improvement pattern can be sustained for extended periods (but not necessarily indefinite, as this particular supplement application needs to be put to rest after a while -> for at least 5-7 days after 6-12 weeks of repartitioning on average).
Most people who partake in sports nutrition go through lean muscle development and weight loss cycles throughout the year. One direction does not necessarily have to be positioned to run counter to the other. One can gain a few more pounds, while maintaining or even further sharpening hardness through the use of insulin mimickers or repartitioning agents combined with modified caloric type and consumption. The recommended products below can be combined by taking one unit or capsule of each with the 2 or 3 largest meals of the day consistently. One should experience lean muscle gain beginning with the first 2 weeks where nutrients are being placed into muscle at a faster more optimized rate. Within a few months new contractile protein should start to form, but remember that gains of this quality come slowly and tend to stay with you.
