Frequently Asked Questions

Everything you need to know about our four core performance supplements — answered clearly, without the BS.

⚡ Creatine Monohydrate
The research-backed dose is 3–5 grams per day. Vitasonic delivers exactly 5g per serving — the amount used consistently in clinical studies. No loading phase required; 3–4 weeks of daily use fully saturates your muscles.
No. There is no scientific evidence that cycling creatine is necessary or beneficial. Long-term daily use is safe and effective for healthy adults. Take it year-round without breaks.
Creatine draws water into muscle cells — which is part of why it works. You may see a 1–2 lb scale increase in week one. This is intramuscular fluid, not fat, and it contributes to the fuller, harder look most users are after.
Yes. All Vitasonic products are manufactured in a USA-based GMP-certified facility and undergo third-party testing for purity and potency before every batch ships. What's on the label is what's in the container.
Absolutely. The recommended stack: Nitric Shock pre-workout → BCAAs intra-workout → creatine + Whey post-workout. This sequence covers energy, performance, recovery, and muscle protein synthesis with zero overlap.
Yes — the benefits are well-documented in women, with similar relative strength and power gains. The same 3–5g daily dose applies. There is no scientific reason to use a lower amount.
💪 BCAA Post Workout
The 2:1:1 ratio is leucine : isoleucine : valine. Leucine is the primary activator of muscle protein synthesis via the mTOR pathway, so it's doubled. This mirrors the natural BCAA profile of skeletal muscle and is what clinical research consistently uses.
Yes — timing makes them complementary. Whey is best post-workout for a full protein dose. BCAAs are ideal during training or fasted workouts — they protect muscle without requiring digestion. Together, you get intra-workout protection and complete post-workout recovery.
BCAAs contain a small number of calories and can technically trigger a minor insulin response. For fasted training performance and muscle preservation, the benefit strongly outweighs this. Most athletes training intermittent fasting use BCAAs intra-workout without issue.
BCAAs — particularly leucine — reduce muscle protein breakdown during and after training. Multiple studies show they blunt DOMS (delayed onset muscle soreness) by reducing muscle damage markers. Less breakdown during a session means faster repair afterward.
🥛 Whey Protein Isolate
Isolate undergoes additional filtration, leaving 90%+ protein by weight with minimal fat and lactose. Concentrate is 70–80% protein with more fat and lactose. Isolate digests faster, causes less bloating in lactose-sensitive individuals, and delivers a cleaner profile per serving.
The most impactful window is within 30–60 minutes post-workout, when muscles are primed for protein uptake. It also works well first thing in the morning or as a high-protein snack. Total daily protein consistency matters more than perfect timing.
Sports nutrition research recommends 1.6–2.2g per kg of bodyweight per day for resistance-trained athletes. For a 180 lb (82kg) person, that's 130–180g daily. One Vitasonic serving delivers 25g — a significant and efficient contribution.
Yes. Whey isolate has extremely low lactose content — most lactose-sensitive individuals tolerate it without the digestive discomfort they experience with concentrate. If you have a full dairy allergy (not just lactose sensitivity), consult a doctor before use.
🔥 Nitric Shock Pre-Workout
Citrulline Malate drives nitric oxide production for greater blood flow and pumps. Beta-Alanine buffers lactic acid to delay fatigue. Caffeine enhances focus, energy, and power output. Every ingredient is at its clinically effective dose — not sprinkled in for label appeal.
Beta-alanine causes a harmless tingling called paresthesia in some users. It's a normal physiological response — not a cause for concern. Taking it with food or splitting the dose can reduce intensity. Most users find it fades within 1–2 weeks of consistent use.
Most pre-workouts mega-dose caffeine and under-dose the performance ingredients. Nitric Shock is built around citrulline malate and beta-alanine first — caffeine supports, not leads. The result is real physical performance improvement, not just a stimulant spike followed by a crash.
For most healthy adults, yes. Because it contains caffeine, we recommend cycling off one week every 6–8 weeks to maintain sensitivity. Avoid taking it within 4–5 hours of bedtime. Always start with a half-serving to assess your tolerance first.
Yes — this is the ideal combination. Nitric Shock 20–30 min before training → BCAAs during → creatine + whey post-workout. These four products cover the entire training window with no redundancy and no ingredient conflicts.

The Science

The Complete Guide to Building Your Performance Stack

📅 Updated 2025· ⏱ 8 min read· 🇺🇸 USA-Formulated Supplements

If you've spent any time in a supplement store or scrolling through fitness content, you already know the industry has a noise problem. Every product promises the world. Most deliver very little. This guide cuts through the marketing and explains exactly what these four Vitasonic Labs performance supplements do, why the science behind them is solid, and how to combine them for maximum effect.

Why Most Supplements Fail You

The supplement industry is largely unregulated when it comes to ingredient dosing. A company can include 50mg of a clinically effective ingredient that requires 6,000mg to produce results — and legally claim it's "in the formula." This practice — called proprietary blending or pixie-dusting — is rampant across the industry.

Vitasonic Labs was built around a single non-negotiable: every active ingredient is listed with its exact dose on the label, and that dose reflects what peer-reviewed research actually supports. Every product is formulated and manufactured in the USA in GMP-certified facilities, and every batch is third-party tested before it ships.

Creatine Monohydrate — The Most Proven Supplement in Sports Science

If you only take one supplement, make it creatine. It is the most studied sports performance supplement in history — over 500 peer-reviewed studies supporting its safety and effectiveness. The mechanism: creatine phosphate stored in your muscles rapidly regenerates ATP (your body's primary energy currency) during high-intensity efforts. More creatine = more ATP = more power output sustained for longer.

The documented benefits: increases in 1-rep max strength (typically 5–15%), greater lean muscle mass gains over a training program, and improved performance during repeated high-intensity efforts. Emerging evidence also supports cognitive benefits — particularly under sleep deprivation or mental fatigue.

Clinical Dosing Note

The research-backed maintenance dose is 3–5g per day. Loading protocols (20g/day for 5–7 days) accelerate saturation but are not required. Daily consistent use for 3–4 weeks produces full muscle saturation without the GI discomfort some experience during loading.

Vitasonic's Creatine Monohydrate delivers exactly 5g of micronized creatine per serving — nothing else, no fillers, no artificial dyes. Micronization improves mixability and absorption, making it simple to add to any shake or beverage.

BCAA Post Workout — Building the Floor Under Your Muscle

Branched-chain amino acids (leucine, isoleucine, valine) are essential — your body cannot make them; they must come from diet or supplementation. They make up roughly 35% of the essential amino acids in muscle protein and are the primary fuel source your muscles oxidize during prolonged exercise.

The role of BCAAs is twofold: they serve as a direct fuel substrate during exercise, and leucine specifically activates the mTOR signaling pathway to initiate muscle protein synthesis. This makes leucine the most anabolic of the three, which is why the 2:1:1 formulation (double the leucine) is preferred — and what Vitasonic uses.

Research consistently shows BCAA supplementation reduces exercise-induced muscle damage, blunts DOMS, and preserves lean muscle during caloric deficits. For fasted training, BCAAs provide critical anti-catabolic protection without requiring full digestion.

How to Use BCAAs Most Effectively

Sip BCAAs during training or take them immediately before fasted workouts. Within 30 minutes of finishing, follow with a complete protein source like Whey Protein Isolate to fully activate muscle protein synthesis and maximize recovery.

Whey Protein Isolate — The Foundation of Muscle Growth

Muscle hypertrophy requires net positive protein balance — more synthesis than breakdown over time. Exercise stimulates synthesis; dietary protein provides the raw material. Resistance training elevates muscle protein synthesis for 24–48 hours, but only if adequate protein is available.

Whey contains all nine essential amino acids, is particularly high in leucine, and has the highest biological value of any protein source. Whey isolate is the most refined form — additional filtration removes most fat and lactose, leaving 90%+ protein by weight with fast absorption and minimal digestive burden. For anyone managing calories or who is lactose-sensitive, isolate is the clear choice over concentrate.

Daily Protein Targets for Muscle Building

Current research recommends 1.6–2.2g of protein per kg of bodyweight per day for resistance-trained athletes. For a 180 lb (82kg) athlete, that's 130–180g daily. One Vitasonic Whey serving delivers 25g — a meaningful contribution toward that target.

Nitric Shock Pre-Workout — Engineered for the Whole Session

Most pre-workouts are expensive caffeine delivery systems. Nitric Shock was built differently — around ingredients that produce measurable performance improvements, with caffeine as a supporting player, not the whole show.

Citrulline Malate converts to arginine in the kidneys, driving nitric oxide production, causing vasodilation — wider blood vessels, more blood flow to working muscles, better oxygen delivery, bigger pumps, and improved muscular endurance. Nitric Shock uses the clinically effective 6–8g dose.

Beta-Alanine combines with histidine to form carnosine in muscle — a buffer against lactic acid (the primary driver of the "burn" during intense sets). More carnosine means delayed fatigue and more reps at high intensity.

Caffeine has an ironclad evidence base for improving endurance, strength, power output, focus, and pain tolerance. Nitric Shock uses a moderate, effective dose — real benefits without the crash or dependency acceleration from mega-dosed formulas.

The Honest Note on Pre-Workouts

No pre-workout replaces adequate sleep, nutrition, and progressive training. What a well-formulated pre-workout does is help you extract more from sessions you're already committed to — improving output at the margin, every session, over time. That compounds into real results.

How to Stack All Four Products

20–30 minutes before training: One serving of Nitric Shock Pre-Workout. Allows citrulline and caffeine to reach peak plasma levels before your first working set.

During training: Sip BCAAs mixed in water. Provides ongoing leucine availability to blunt catabolism — especially critical during longer sessions or fasted workouts.

Immediately post-workout: Take 5g of Creatine Monohydrate, then within 30 minutes consume one serving of Whey Protein Isolate. This covers ATP resynthesis, anti-catabolism, and muscle protein synthesis in a single post-workout window.

On non-training days: skip the pre-workout and BCAAs. Take your creatine daily — consistency is critical for maintaining muscle saturation — and meet your protein targets through whole food and whey as needed.

Why USA-Made Matters

In the United States, GMP-certified supplement manufacturers are held to strict standards: ingredient identity verification, dose accuracy, contamination prevention, and batch record-keeping. Third-party testing adds independent verification — ensuring the label matches what's actually in the bottle, at the stated dose.

All Vitasonic Labs products are formulated and manufactured in American GMP-certified facilities. Every batch is third-party tested before it ships. If you're putting something in your body every day, you deserve to know exactly what it is, where it came from, and how it was verified. That standard is built into every Vitasonic product.
