USN All9 Aminos

USN ALL9™ Aminos 330g — All Nine Essential Amino Acids Plus Glutamine

ALL9™ delivers the complete essential amino acid spectrum rather than BCAAs alone: 4,000mg of BCAAs, 820mg of additional EAAs and 1,300mg of L-glutamine per serve, formulated to support recovery, stamina and hydration. 330g. In stock at TopDog Nutrition.

Why All Nine Beats BCAAs Alone

This is the most useful thing to understand about amino supplements, and it explains the product's name.

There are nine essential amino acids, ones your body cannot manufacture and must obtain from food. BCAAs are three of them: leucine, isoleucine and valine.

Building muscle protein requires all nine. Leucine is the trigger — it activates the mTOR pathway that switches muscle protein synthesis on — but a trigger without ammunition doesn't build anything. Supplying BCAAs alone signals your body to build while withholding six of the amino acids it needs to actually do it.

The research is consistent on this: EAAs outperform BCAAs alone for stimulating muscle protein synthesis. A BCAA-only product is an incomplete version of what ALL9™ delivers.

The 1,300mg of L-Glutamine

Glutamine is the most abundant free amino acid in the body, and the one depleted fastest under heavy training load.

Your body produces it, which is why it's classed as non-essential under normal conditions. The problem is what "normal" means. Under intense training, illness or a calorie deficit, demand outstrips production and muscle glutamine stores get drawn down to cover the shortfall.

The knock-on effects matter, because glutamine isn't only a muscle amino acid. It's the primary fuel source for the cells lining your intestine and a key substrate for immune cells. When stores are depleted, muscle recovery, gut integrity and immune function are all affected at once, which is why heavy training blocks so often come with getting sick.

Hydration Support

Hydration is the most underrated performance variable in training. Even mild dehydration measurably reduces strength output and endurance, and it rarely feels like a supplement problem. It just feels like a bad session.

An amino drink sipped through a workout serves two purposes at once: it gets amino acids in, and it gets fluid in. For a lot of people the second is doing more work than the first.

Where It Genuinely Helps

Straight answer: if your daily protein intake is already adequate, an amino supplement adds relatively little. Whey protein already contains the full EAA spectrum.

Where ALL9™ earns its place:

• Fasted training — free-form aminos absorb without digestion, giving your body something to draw on.
• Long sessions — a protein shake sits heavily mid-workout; an amino drink doesn't.
• Cutting phases — restricted calories with lean tissue to preserve.
• Getting fluid in — realistically a large part of why people drink it. A flavoured drink gets consumed; plain water often doesn't.

Directions

Mix one serve with cold water and sip during training, or take it across the day to raise total amino intake.

Stimulant-free, so there's no timing restriction and no conflict with a pre-workout. Take your pre-workout before, sip ALL9™ during.

Frequently Asked Questions

Does it replace protein powder?

No. Free-form aminos are not the same as 25g of complete protein. This supplements a diet that already has enough protein in it.

BCAAs or EAAs?

EAAs, and this gives you both. BCAAs alone signal muscle protein synthesis without supplying the full set of amino acids needed to complete it.

Can I take it with a pre-workout?

Yes. It's stimulant-free, so there's no doubling up.

Can I take it on rest days?

You can, and the hydration is useful. If your protein intake is on track, the aminos do less on a rest day.
