BCAA Injectable 65 mg
Description
What is BCAAs (Astera Labs)?
Injectable BCAAs at 65mg per ml. Worth being straight about the arithmetic: an oral serving is measured in grams, and this vial holds well under one.
Leucine, isoleucine and valine are the three branched-chain amino acids, and they are unusual in being broken down in muscle rather than in the liver. Leucine is the one that matters most, since it triggers the signalling pathway that starts muscle protein synthesis. Injecting delivers them directly rather than through digestion.
BCAAs benefits
- Delivered directly rather than through digestion
- Leucine triggers the pathway that starts muscle protein synthesis
- No stomach load, which matters if you train fasted
- Not hormonal, so nothing is suppressed and no post-cycle therapy applies
BCAAs dosage
- Standard
- 1ml around training
- BCAAs per ml
- 65mg
- Total per vial
- 650mg
- Amino acids
- Leucine, isoleucine and valine
- Route
- Intramuscular for preference
- Volume
- 10ml
1ml around training. Be clear about the scale. A standard oral BCAA serving is five to ten grams; the entire vial here is 0.65 grams. Injecting improves how much reaches you, but not by anything like the factor that gap would need.
Where it makes sense is as an addition to adequate protein intake, not as a replacement for it.

Who is BCAAs for?
People who train fasted and want something with no stomach load, and anyone who prefers the injectable format across this whole range.
If you are choosing this over an oral BCAA powder on effectiveness, the arithmetic does not support it. If you are already eating enough protein, BCAAs of any kind add little; if you are not, food is the answer before either format.
How to use BCAAs
Draw 1ml and inject subcutaneously or intramuscularly. Intramuscular is preferred, since these solutions can irritate under the skin. Rotate sites and wipe the stopper before every draw. The injection technique guide covers it.
Frequently asked questions
Is this better than oral BCAA powder?
Not on dose, and it would be misleading to suggest otherwise. An oral serving is five to ten grams; this whole vial is 0.65 grams.
Injecting does improve how much reaches your bloodstream, but not by the factor needed to make those comparable. What it offers is no stomach load and a format that suits training fasted.
Do I need BCAAs at all?
If you are eating enough protein, mostly no, and that is worth knowing before buying either format. Whole protein already contains all three.
Where they earn a place is around fasted training or when protein intake is genuinely low, which on a hard cut it sometimes is.
What is the ratio of the three?
It is not stated on this product, and we would rather tell you that than guess.
It matters because leucine is the one that triggers muscle protein synthesis, and most oral products use a 2:1:1 or 4:1:1 ratio weighted toward it. Ask before ordering if it matters to your use.
When should I use it?
Around training, and particularly if you train fasted, since that is the situation where having no stomach load is worth something.
Outside that window, food does the same job better.
Does it need cycling?
No. These are amino acids, nothing is hormonal and there is nothing to recover from.
Use it around training for as long as it suits you.
