That is normal and necessary \u2014 it is the signal to adapt. The problem is <strong>hypercatabolism<\/strong>: the excessive breakdown of muscle protein that happens when training volume, intensity or frequency outruns your ability to recover. Pro athletes live in this state for weeks at a time; ambitious amateurs hit it every time they ramp up a block.<\/p>\n<p>When breakdown exceeds what your post-workout recovery can repair, the result is predictable: lean mass drifts down, soreness lingers, performance plateaus and the risk of overuse injury climbs. No amount of protein <em>after<\/em> the session fully closes that gap.<\/p>\n<p><strong>Anti-catabolic factors<\/strong> are nutrients that reduce the rate of muscle protein breakdown. Taken before and during training, they lower the damage done \u2014 so your recovery nutrition has less to repair and does its job better. That is exactly what SCN\u2122 Anti-Catabolic Activa.TOR\u2079 is built for, with the two most researched anti-catabolic nutrients at doses most <strong>HMB supplements<\/strong> do not come close to.<\/p>\n<div class=\"band\">6.4g free-acid HMB + 6.4g Ajipure\u00ae L-Leucine per serving<small>Pharmaceutical-grade ingredients.

Only around 5% of the leucine you eat is converted to HMB, which is why supplementing it directly makes sense. Gram for gram, HMB is more potent than leucine at <strong>attenuating muscle protein breakdown<\/strong>, while leucine is the stronger trigger of <strong>muscle protein synthesis<\/strong> \u2014 which is exactly why this formula contains both. We use the free-acid form (HMB-FA), shown in human pharmacokinetic studies to appear in the blood faster and reach higher peak concentrations than calcium-HMB. Most HMB supplements give you 1\u20133g of calcium-HMB per day. Anti-Catabolic Activa.TOR\u2079 gives you 6.4g of the free acid in a single pre-training serving.<\/p>\n<p class=\"why\">Why it&#8217;s here: the single most researched anti-catabolic nutrient in sport, at a dose that respects the science.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"ing\">\n<div class=\"dose\"><b>6,400mg<\/b><span>per serving<\/span><\/div>\n<div>\n<h4>Ajipure\u00ae L-Leucine (Ajinomoto\u00ae) \u2014 instantised<\/h4>\n<p>Leucine is the &#8220;master&#8221; branched-chain amino acid. It directly activates mTOR, the cellular switch that drives muscle protein synthesis, and does so far more strongly than isoleucine or valine \u2014 gram for gram, leucine on its own is more effective at triggering protein synthesis than the same amount of a mixed BCAA. Leucine appears to reliably raise muscle protein synthesis after meals and training, and research suggests it is particularly useful when dietary protein is lower than ideal and in older adults, where the muscle&#8217;s response to protein is blunted. We use Ajipure\u00ae from Ajinomoto\u00ae: pharmaceutical-grade, fermented from plant carbohydrates, never from animal sources, and instantised so it dissolves immediately in water.<\/p>\n<p class=\"why\">Why it&#8217;s here: HMB slows breakdown; leucine switches on rebuilding. Together they cover both sides of the muscle equation.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"ing\">\n<div class=\"dose\"><b>13,700mg<\/b><span>per serving<\/span><\/div>\n<div>\n<h4>Polimero altamente ramificato Amilopectina<\/h4>\n<p>A high-molecular-weight, highly branched carbohydrate that empties from the stomach quickly and is absorbed smoothly, without the heavy, bloated feeling of simple sugars.

This is why Anti-Catabolic Activa.TOR\u2079 is a powder you drink around training rather than a capsule you swallow at breakfast.<\/p>\n<p class=\"why\">Why it&#8217;s here: fuel plus a delivery vehicle for the actives \u2014 in one scoop.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"ing\">\n<div class=\"dose\"><b>370 mg<\/b><span>per serving<\/span><\/div>\n<div>\n<h4>Magnesium Bisglycinate (MagPlex\u2074)<\/h4>\n<p>Magnesium bound to two molecules of the amino acid glycine. One of the best-tolerated and most bioavailable forms, with no laxative effect at effective doses. Glycine itself is calming, which makes bisglycinate the form most often chosen for relaxation and sleep quality \u2014 a real recovery lever for athletes training twice a day. Magnesium contributes to normal muscle function, normal protein synthesis, electrolyte balance and the reduction of tiredness and fatigue.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"ing\">\n<div class=\"dose\"><b>370 mg<\/b><span>per serving<\/span><\/div>\n<div>\n<h4>Magnesium Glycerophosphate (MagPlex\u2074)<\/h4>\n<p>Magnesium attached to glycerol and phosphate. Once the bond is cleaved, all three components are available: magnesium, plus phosphate and glycerol that the body can use in energy (ATP) production. Around a quarter of the body&#8217;s magnesium sits in muscle, where it is required for muscle relaxation \u2014 the counterpart to calcium&#8217;s role in contraction.

Citrate is also a Krebs-cycle intermediate, which fits a product designed to be used around training.

Athletes lose magnesium in sweat and urine; even marginal shortfalls are believed to affect performance and recovery, and dietary intake is frequently below what high training loads demand. MagPlex\u2074 covers that gap with four forms, 1,460mg of elemental-equivalent compound in total, in one scoop.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"ing\">\n<div class=\"dose\"><b>17 mg<\/b><span>per serving<\/span><\/div>\n<div>\n<h4>Pyridoxal 5\u2032-Phosphate (P5P, active Vitamin B6)<\/h4>\n<p>P5P is the coenzyme form of vitamin B6 \u2014 the form your body actually uses \u2014 so it bypasses the liver conversion step that ordinary pyridoxine requires. Vitamin B6 contributes to normal protein and glycogen metabolism, normal energy-yielding metabolism, normal functioning of the nervous system and the reduction of tiredness and fatigue. B vitamins are water-soluble and lost in sweat and urine; research in active individuals links low B-vitamin status to poorer high-intensity performance and a reduced ability to repair and build muscle. In a formula built around amino-acid metabolism, B6 is the cofactor that makes the machinery run.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"ing\">\n<div class=\"dose\"><b>10 mg<\/b><span>per serving<\/span><\/div>\n<div>\n<h4>BioPerine\u00ae (black pepper extract, 95% piperine)<\/h4>\n<p>BioPerine\u00ae from Sabinsa is the original patented, standardised piperine extract.

In plain terms: it helps the rest of the formula go where it is supposed to go.<\/p>\n<p class=\"why\">Why it&#8217;s here: you paid for 6.4g of HMB and 6.4g of leucine.

In human trials it reaches peak plasma concentration in roughly a quarter of the time of calcium-HMB, achieves a higher peak, and shows greater overall availability to tissue. It is the form used in the landmark 12-week studies in resistance-trained athletes that reported improvements in lean mass, strength and power alongside lower markers of muscle damage.<\/p>\n<\/p><\/div>\n<div class=\"card\">\n<h4>Calcium HMB (Ca-HMB) \u2014 the common form<\/h4>\n<p>HMB bound to calcium, the form found in most capsules and tablets on the market. Effective and well-studied in its own right, but slower to absorb and typically dosed at 1\u20133g per day split across the day.

In runners completing a 20km race after six weeks of HMB supplementation, post-race markers of muscle damage (creatine kinase and LDH) were significantly lower than in the placebo group \u2014 early evidence of HMB&#8217;s relevance to endurance sport, not only strength sport.<\/span><\/div>\n<div class=\"study\"><b>HMB meta-analysis: lean mass and strength<\/b><span>Nissen &amp; Sharp, <em>Journal of Applied Physiology<\/em> (2003). Pooling the available randomised trials, HMB was one of only two supplements with consistent evidence for increasing lean body mass and strength with resistance training \u2014 the other being creatine.<\/span><\/div>\n<div class=\"study\"><b>International Society of Sports Nutrition position on HMB<\/b><span>Wilson et al., <em>JISSN<\/em> (2013). The ISSN concluded that HMB can enhance recovery by attenuating exercise-induced muscle damage, and that the benefit is greatest when training is intense, high-volume and novel \u2014 exactly the conditions in which athletes overreach.<\/span><\/div>\n<div class=\"study\"><b>Leucine supplementation and endurance performance<\/b><span>Crowe et al., <em>European Journal of Applied Physiology<\/em> (2006). Six weeks of daily leucine supplementation in competitive outrigger canoeists improved rowing time to exhaustion and upper-body power, with lower perceived exertion, compared with placebo.<\/span><\/div>\n<div class=\"study\"><b>Magnesium and performance in athletes<\/b><span>Setaro et al., <em>Journal of Sports Sciences<\/em> (2014). In elite volleyball players, four weeks of magnesium supplementation improved jump performance alongside changes in lactate handling; the authors note that athletes frequently consume less magnesium than training demands.<\/span><\/div>\n<div class=\"study\"><b>B-vitamin status and athletic performance<\/b><span>Woolf &amp; Manore, <em>International Journal of Sport Nutrition and Exercise Metabolism<\/em> (2006). A review of B-vitamin requirements in active people concluded that exercise increases the need for several B vitamins, including B6, and that marginal status may impair high-intensity performance and the body&#8217;s ability to repair and build muscle.<\/span><\/div>\n<p class=\"note\">Studies are cited for information on the individual ingredients and their researched doses and forms.

HMB is the more potent anti-catabolic (it slows muscle protein breakdown); leucine is the more potent anabolic signal (it switches on muscle protein synthesis). Most products give you one or the other at a small dose. Anti-Catabolic Activa.TOR\u2079 gives you 6.4g of each.<\/p>\n<\/details>\n<details>\n<summary>Why 6.4g of HMB when most products use 3g?<\/summary>\n<p>The 3g figure comes from studies using daily, divided dosing. This product is designed for a single pre-\/intra-training serving on training days only, delivering a full anti-catabolic dose at the moment of maximum muscle stress. The free-acid form is also absorbed faster than the calcium-HMB most 3g products use.<\/p>\n<\/details>\n<details>\n<summary>Should I take it on rest days?<\/summary>\n<p>It is formulated for training days, and one tub covers 15 of them. If you are in a hard cutting phase or a very high-volume block and want daily cover, speak to us and we will advise on how to combine it with the rest of the SCN\u2122 range.<\/p>\n<\/details>\n<details>\n<summary>Does it work for endurance athletes or just lifters?<\/summary>\n<p>Most HMB research is in strength athletes, but the mechanism \u2014 lower muscle protein breakdown and lower muscle-damage markers \u2014 applies to any demanding training. Studies in distance runners show reduced damage markers after prolonged running, and leucine trials in endurance athletes show improved time to exhaustion. SCN\u2122 built this for endurance athletes first.<\/p>\n<\/details>\n<details>\n<summary>Is it vegan and doping-safe?<\/summary>\n<p>Ajipure\u00ae leucine is fermented from plant carbohydrates with no animal-origin materials. Like every SCN\u2122 product, Anti-Catabolic Activa.TOR\u2079 is manufactured to be 100% doping-free and cross-contamination safe. Always check with your federation if you compete under anti-doping rules.<\/p>\n<\/details>\n<details>\n<summary>Can I combine it with creatine, protein or electrolytes?<\/summary>\n<p>Yes.
