Anabolic Resistance: The Silent Gains Killer
Jeremy BriggsShare
Feel the burn. Fight the fade.
Every rep you grind out triggers muscle protein synthesis (MPS)—the engine that rebuilds your fibers stronger, leaner, meaner. But here’s the catch: anabolic resistance is like rust on that engine. It’s when your muscles stop responding to the usual signals—protein, exercise, amino acids—that spark MPS. You’re putting in the work, slamming the weights, but the gains? They’re stalling. Why? Your body’s whispering, “Not today.”
This isn’t just a theory—it’s physiology. As we age, or when we slack on training or protein intake, our muscles get stubborn. The mTOR pathway, the master switch for MPS, flickers instead of roaring. Leucine, the amino acid kingpin that flips that switch, hits a wall. The result? Less muscle repair, slower recovery, and a physique that’s stuck in neutral.
The Science: Why It Happens
Anabolic resistance creeps in through a few heavy hitters:
- Aging: After 30, it’s a slow grind. Studies like Moore et al. (2015) show older adults need more protein—up to 40g per dose—versus the 20g that works for the young guns. Why? Muscle cells in older bodies have a dulled response to leucine and exercise. MPS peaks lower and fades faster. By 65, you’re looking at a 30-40% drop in sensitivity compared to your 20s.
- Inactivity: Sit on the couch too long, and your muscles forget how to grow. Sedentary lifestyles blunt insulin sensitivity and mTOR signaling, making every scoop of protein less effective. Research (Breen et al., 2013) shows even a week of bed rest slashes MPS response by 30%.
- Low Protein Intake: Skimp on the good stuff, and your muscles starve. If you’re not hitting 1.6-2.2 g/kg/day, your amino acid pool’s too shallow to fight resistance. Chronic underfeeding amplifies it—your body prioritizes survival over growth.
- Fasting or Calorie Deficits: Go hard on fasting or cutting, and MPB (muscle protein breakdown) outpaces MPS. Post-fasting, your muscles are primed but fragile—without a fast protein hit, anabolic resistance digs in deeper.
The data’s clear: Buckley et al. (2008) showed sedentary guys taking Progenex-style WPH recovered peak torque in 6 hours—proof that rapid amino acid delivery overcomes resistance barriers. Compare that to WPI’s 48-hour crawl. Speed matters.

Crushing Anabolic Resistance with Progenex More Muscle
Step up. Strike fast. Anabolic resistance doesn’t have to win—you’ve got Progenex Recovery, the hydrolyzed whey isolate (WPH) that rewrites the rules. Here’s how it smashes through:
- Rapid Absorption: WPH is pre-digested—peptides so small they hit your bloodstream in minutes, not hours. Tang et al. (2009) showed WPH spikes MPS higher and faster than casein or soy. For older lifters or post-fasting warriors, this speed blasts past dulled receptors.
- Leucine Load: Progenex packs a leucine punch—around 2.5-3g per 25g serving, the threshold to trigger mTOR even in resistant muscles. Studies (Katsanos et al., 2006) prove 40g of leucine-rich whey overcomes age-related resistance, matching young MPS rates.
- Post-Fasting Power: After a fast, MPB’s raging. A 2013 study (Tipton et al., 2013) found fasted trainees gained ~400% more MPS with immediate protein. Progenex’s instant delivery flips the switch, turning catabolism into an anabolic explosion.
- Recovery Rocket: Buckley’s 6-hour recovery stat isn’t just for newbies—it’s a blueprint. Anabolic resistance slows repair; Progenex accelerates it, getting you back to peak performance when others are still sore.
The Bigger Picture: Context is Everything
Sure, total protein (1.6-2.2 g/kg/day) builds the base—Schoenfeld et al. (2013) nailed that. But anabolic resistance shifts the game. Older lifters, fasted grinders, or twice-a-day beasts need more than totals—they need timing and type. Critics saying “no window” miss this: their WPI or chicken tests don’t match Progenex’s WPH velocity. It’s like racing a sedan against a supercar—same road, different results.
Your Move: Progenex vs. Resistance
Own it. Anabolic resistance is real—but it’s not invincible. Age creeping up? Slam 31g of Progenex More Muscle post-workout to match the young guns. Fasting to shred? Hit it within 30 minutes to reclaim your gains. Training twice daily? Recover in 6 hours, not 48. This isn’t just protein—it’s precision. It’s science. It’s your physique, redefined.
Direct the doubters here. Let them argue with Buckley’s data, with leucine’s might, with Progenex’s proof. You? You’ll be too busy building a body that shuts them up. Just Do It.
