About Jim Stoppani →
Jim Stoppani is an exercise physiologist, author, and sports nutrition entrepreneur. He received his doctorate in exercise physiology with a minor in biochemistry from the University of Connecticut and completed a postdoctoral fellowship at the John B. Pierce Laboratory and Yale University School of Medicine, studying the effects of exercise and diet on gene regulation in muscle tissue. He received the 2002 Gatorade Beginning Investigator in Exercise Science Award from the American Physiological Society. From 2002 to 2013 he served as Senior Science Editor for Muscle & Fitness, Muscle & Fitness Hers, and Flex magazines. He founded JYM Supplement Science in 2013 and runs the training and nutrition platform JimStoppani.com. He is the author of Jim Stoppani's Encyclopedia of Muscle & Strength and co-author of the New York Times bestseller LL Cool J's Platinum 360 Diet and Lifestyle.

In a protocol Alternative
Older adults can take 5–6 g BCAAs (with leucine:isoleucine:valine at 2:1:1) 15–30 minutes before a meal to overcome age-related anabolic resistance and reach the leucine threshold without high food volume.
“I'll pop about 5 to 6 grams of branch chain amino acids.

Take creatine before workouts so muscle levels are topped off when you need anaerobic energy.
“why wouldn't you want to take it before you exercise to make sure your levels are topped off?
TD▶ 15:00DosageTake pre-workoutCaveatsCreatine's main effect is chronic muscle saturation, not acuteCertaintyhedgedrecommendation -

Take creatine with a carbohydrate/insulin source to boost muscle uptake by 20–40% via the insulin-sensitive creatine receptor.
“creatine receptor... works better when there's insulin.
TD▶ 9:00DosageTake with carbs, sugar, or a protein shake; ideally pre-workoutCaveatsIf black coffee works for adherence, you'll still absorb enough without carbsCertaintyexplicitrecommendation -
A single high dose of creatine (20–25 g) can blunt the cognitive hit of sleep deprivation; Stoppani uses higher doses when traveling for jet lag.
“They took a single dose of 25... significantly reduced the hit from the sleep deprivation.

Women over 40 (and even younger) should consider creatine for muscle maintenance against sarcopenia and for brain-boosting benefits.
“Should every woman over 40, even under 40... be interested. Absolutely, yes.
TD▶ 0:59Dosage3–5 g/day baseline; closer to 10 g/day for brain benefitsCertaintyexplicitstrong endorsement -
Stoppani prefers creatine HCl over monohydrate because it dissolves completely in cold water, avoiding the GI/bloating issues caused by undissolved monohydrate particles.
“That's why I prefer hydrochloride.

Organic (prompted) Alternative
Take creatine monohydrate in warm coffee to improve its poor solubility; the acidity and warmth help it dissolve.
“if you mix creatine in a warm fluid, it'll go into solution far better.

Do low-rep sets (~5 reps) with lighter weight moved as fast as possible to activate fast-twitch fibers, which are lost first with aging.
“explosive reps... activate the fast twitch muscle fibers.
TD▶ 31:52Dosage~5 reps of lightweight moved as fast as possible (stop because speed drops, not fatigue)Certaintyexplicitstrong endorsement -

Lift heavy weights for ~5 reps (where 5 is your true max) to maximize strength gains—high-rep light lifting won't build strength as effectively.
“5 rep set... a weight... No limits to five reps.

Supplemental leucine taken 15–30 min before a meal (not with it) helps reach the ~3 g leucine MPS threshold, especially valuable for older adults.
“I would take it about 15 to 30 minutes before the meal.

Aim for roughly 1 gram of protein per pound of body weight daily for resistance trainees and those wanting muscle, strength, or fat loss.
“0.7 to 0.9 grams of protein per pound of body weight... round it up to one.

Organic (prompted)
Aim for ~40 g of protein per meal (50–60 g for older adults) to deliver ~3 g leucine and maximize muscle protein synthesis.
“it takes for most people about 3 grams of leucine to maximize muscle protein synthesis.

Everyone should do resistance training at least twice a week, including some heavy lifting—not just light toning work.

Whey is the highest-leucine protein source (~12%), making 30 g sufficient to hit the 3 g leucine threshold.

Avoid supplements that list ingredients without specifying doses, or that claim 'hyper-concentrated' equivalency—these typically under-dose key ingredients.
