If you're a health nut, you've probably used or at least heard of creatine as part of your fitness goals. But according to one GNC worker, there's another

The Surprising Hidden Benefit of GNC Creatine That's Taking Over TikTok

In the ever-evolving world of fitness supplements, creatine has long been a staple for athletes, bodybuilders, and gym enthusiasts looking to boost their performance and build muscle. Sold widely at retailers like GNC, this compound is renowned for its ability to enhance strength, increase lean muscle mass, and improve overall workout efficiency. But recently, a wave of viral content on platforms like TikTok has uncovered what many are calling a "hidden use" for GNC's creatine products—one that's particularly appealing to those chasing aesthetic goals beyond just bulking up arms or chests. This unexpected twist involves using creatine to target and enhance glute development, leading to what users enthusiastically dub "booty gains." As a journalist diving into health and culture trends, I've explored this phenomenon, speaking with experts and scrolling through countless user testimonials to unpack why this supplement is suddenly the talk of the town for a very specific body part.

Creatine, in its most basic form, is a naturally occurring substance found in muscle cells. It's produced by the body from amino acids like glycine, arginine, and methionine, and it's also present in foods such as red meat and fish. When supplemented—often in the form of creatine monohydrate, which is the most common and research-backed variant available at GNC—it helps replenish adenosine triphosphate (ATP), the energy currency of cells. This allows for more intense and prolonged workouts, leading to greater muscle hypertrophy over time. Traditionally, it's been marketed to men aiming for that chiseled physique, with benefits including improved power output during high-intensity exercises like weightlifting or sprinting. Studies from organizations like the International Society of Sports Nutrition have consistently shown that creatine can increase muscle mass by 2-4 pounds in the first week due to water retention in muscles, followed by longer-term gains from enhanced training capacity.

But the "hidden use" that's exploding online isn't about bench presses or bicep curls—it's about sculpting a fuller, more pronounced posterior. TikTok creators, predominantly women in their 20s and 30s, have been sharing transformation stories where they've incorporated GNC creatine into their routines specifically to amplify glute growth. One viral video, which has amassed millions of views, features a fitness influencer demonstrating her before-and-after photos, crediting a daily dose of 5 grams of creatine mixed with her post-workout shake for adding noticeable volume to her glutes. "I thought creatine was just for guys getting swole," she says in the clip, "but it's given me the peach emoji vibes I've always wanted." Comments sections are flooded with similar anecdotes: "Started taking GNC creatine two months ago, and my jeans don't fit the same—booty for days!" or "Hidden gem for us girls who squat but need that extra push."

This trend isn't entirely baseless from a scientific standpoint. While creatine doesn't magically target one muscle group over another, its effects on overall muscle recovery and growth can indeed benefit glute-focused training. The glutes—comprising the gluteus maximus, medius, and minimus—are the largest muscle group in the body, responsible for hip extension, abduction, and rotation. Exercises like squats, deadlifts, lunges, and hip thrusts heavily recruit these muscles, and when paired with creatine supplementation, users report being able to lift heavier weights for more reps, leading to progressive overload. This is key for hypertrophy, the process where muscle fibers break down and rebuild stronger and larger. Additionally, creatine's role in drawing water into muscle cells can create a temporary volumizing effect, which might make glutes appear fuller sooner, providing that motivational boost to stick with a regimen.

Experts I've consulted emphasize that this isn't a shortcut but an enhancer. Dr. Elena Ramirez, a sports nutritionist based in Los Angeles, explains, "Creatine supports ATP regeneration, which means you can train harder and recover faster. For women targeting glutes, combining it with resistance training and a protein-rich diet can yield impressive results. The 'hidden' aspect comes from the fact that creatine was historically underrepresented in female fitness circles due to myths about it causing bloating or weight gain. But in reality, any initial water retention often evens out, and the long-term benefits outweigh it." Ramirez points to research from the Journal of the International Society of Sports Nutrition, which indicates that women respond to creatine similarly to men, with potential improvements in lower-body strength that directly impact glute development.

GNC, as a leading retailer, has capitalized on this buzz without explicitly marketing it as a "booty booster." Their creatine monohydrate powder, available in unflavored or flavored options, is priced affordably and comes with straightforward dosing instructions—typically a loading phase of 20 grams per day for a week, followed by 3-5 grams daily. Users on TikTok often highlight GNC's product for its purity and lack of fillers, making it a go-to choice. One creator even did a "GNC haul" video, pairing the creatine with protein bars and pre-workout supplements, framing it as her secret weapon for curvier hips. This grassroots marketing has driven sales, with reports of increased foot traffic to GNC stores from a demographic that might not have shopped there before.

Of course, no supplement is without caveats. While creatine is generally safe and one of the most studied ergogenic aids, with minimal side effects for most people, it's not for everyone. Those with kidney issues should consult a doctor, as creatine can strain renal function in rare cases. There's also the myth-busting needed around weight gain: Yes, you might see the scale tip up initially due to water, but it's not fat—it's muscle-bound hydration that supports growth. Women in particular have expressed concerns about "looking bulky," but influencers counter this by sharing how targeted training keeps the gains localized. "I didn't turn into the Hulk," one TikToker jokes. "I just got the curves I wanted without losing my femininity."

The cultural ripple effects of this trend are fascinating. In a social media landscape obsessed with body positivity and aesthetic ideals, creatine's pivot from bro-science staple to female empowerment tool reflects broader shifts. It's democratizing access to performance enhancers, encouraging more women to hit the weights without fear. Fitness communities on Reddit and Instagram are abuzz with threads like "Creatine for Glute Gains: Real or Hype?" where users swap progress pics and tips. Some even blend it into smoothies with collagen for skin benefits or pair it with yoga for balanced routines.

Beyond the physical, this hidden use taps into psychological wins. Building a stronger, more shapely backside isn't just about looks—it's about confidence, posture, and functional strength. Strong glutes improve athletic performance in everything from running to dancing, reduce injury risk, and even alleviate lower back pain. As one user put it in a heartfelt post, "GNC creatine didn't just give me a bigger butt; it gave me the power to own my body on my terms."

In wrapping up, while the science backs creatine's role in muscle enhancement, the TikTok-fueled discovery of its glute-boosting potential feels like a fresh chapter in supplement lore. Whether you're a seasoned lifter or a newbie inspired by viral videos, incorporating GNC creatine could be the edge you need for those coveted curves. Just remember: Supplements enhance, not replace, consistent training and nutrition. If this trend teaches us anything, it's that sometimes the most effective tools have benefits hiding in plain sight, waiting for the right community to uncover them. As the videos keep rolling in, one thing's clear—this isn't just a fad; it's a movement reshaping how we view fitness one squat at a time.
