A popular TikToker named Cillian Domican decided to put creatine to the test in a simple yet revealing way. He trained consistently for three months while supplementing with creatine and then continued his workouts for another three months without it. Afterward he shared a side by side comparison video that quickly sparked lively discussions online. Many viewers immediately pointed out how his physique appeared fuller and more muscular during the supplementation phase while looking noticeably leaner once he stopped even though training never paused. The experiment highlights how this common supplement can influence not just performance but also day to day appearance in the gym mirror.
Creatine occurs naturally in foods such as meat and dairy products while the body also produces it in the liver kidneys and pancreas. Roughly ninety five percent of it travels to skeletal muscles where it helps generate quick bursts of energy during intense efforts. The remaining portion supports the heart brain and other tissues. As a dietary supplement it comes in powders tablets liquids or even bars and people often turn to it to boost strength and speed up recovery between sets. Experts note that creatine does not directly build muscle tissue on its own yet it enhances workout quality which in turn supports better gains over time.
Fitness nutritionist and researcher Alan Aragon has called creatine the undisputed king of supplements. He explains that it improves a wide range of functions from joint health and muscle growth to athletic performance blood sugar regulation and even memory and cognitive abilities. Aragon points to more than a thousand studies most of which deliver positive findings. In one typical comparison the group using creatine saw strength increases around twenty percent while the placebo group managed about twelve percent. That gap might seem modest on paper but it compounds over weeks and months of dedicated training.
In Cillian Domican’s case the visual shift stood out clearly to commenters. During the three months on creatine his muscles looked pumped and dense in the photos. After stopping the supplement while keeping the same training rhythm his frame took on a slimmer more defined look. Some observers joked that he appeared deflated others praised the leaner aesthetic as a welcome change. The debate quickly moved beyond his personal results to broader questions about water retention muscle fullness and whether everyday gym goers would notice similar transformations.
Many regular lifters already rely on creatine for its reliable benefits without dramatic side effects when used properly. It helps push through extra reps and recover faster which often leads to progressive overload and long term progress. Still individual responses vary based on diet baseline creatine levels and how intensely someone trains. Those who eat plenty of red meat may already have higher natural stores so the added boost might feel subtler. Hydration also plays a key role because creatine draws water into muscle cells which contributes to that fuller appearance many appreciate.
The conversation around Cillian’s video reminds us that supplements work best as part of a solid foundation of consistent training smart nutrition and adequate rest. Creatine stands out because it is one of the few products with such extensive research backing its safety and effectiveness for healthy adults. Whether the goal is adding strength packing on size or simply squeezing more out of every session this supplement continues to earn its reputation. At the same time stories like this one show that stopping it does not erase hard earned progress as long as workouts stay on track.
Ultimately visible changes depend on many factors beyond any single powder. Genetics starting point and overall lifestyle all shape the outcome. Cillian Domican’s honest before and after clip cuts through the hype and lets people judge for themselves. It encourages anyone curious about creatine to consider their own goals and perhaps consult a professional before starting or stopping.
