What is Burn (Astera Labs)?
The most complete of the fat blends here: a full carnitine dose plus the lipotropic three and ATP. It supports a deficit rather than replacing one.
Two things working together. L-carnitine at 200mg carries fatty acids into the mitochondria where they can be burned, which is the transport step. Methionine, inositol and choline are the lipotropics, helping the liver process and move fat rather than store it. ATP is included for the energy side.
Burn benefits
- L-carnitine at 200mg per ml, the highest dose in this range
- Lipotropic support from methionine, inositol and choline alongside it
- Injectable carnitine avoids the poor oral absorption that limits capsules
- ATP included for the energy side rather than only the fat side
- Not hormonal, so nothing is suppressed and no post-cycle therapy applies
Burn dosage
- Standard
- 1ml, 2 to 3 times per week
- L-carnitine
- 200mg per ml
- Choline
- 50mg per ml
- L-methionine
- 25mg per ml
- Inositol
- 25mg per ml
- ATP
- 25mg per ml
1ml two to three times a week, intramuscular for preference. Many people time it before fasted cardio, since that is when the transport step matters most.
Be realistic about what a lipotropic injection does. Methionine, inositol and choline help the liver process and move fat rather than removing it, and the evidence that they produce meaningful weight loss on their own is thin. They support a deficit; they do not replace one. Where they earn their place is alongside a diet that is already working, and for the liver support that comes with them.

Who is Burn for?
People already in a deficit who want the fullest blend on this shelf. If you are choosing one product from this range for fat loss, this is the one with the most in it.
If you only want the lipotropics without the carnitine, Lipo Burn costs less and is the simpler version.
Before you use it. Be realistic about what a lipotropic injection does. Methionine, inositol and choline help the liver process and move fat rather than removing it, and the evidence that they produce meaningful weight loss on their own is thin. They support a deficit; they do not replace one. Where they earn their place is alongside a diet that is already working, and for the liver support that comes with them. Injection site soreness is common with these blends, which is why intramuscular is preferred over subcutaneous. Nothing in it is hormonal, so nothing is suppressed and no post-cycle therapy applies. Store cool, dry and out of direct sunlight. Not for anyone under 18, and not for women who are pregnant or breastfeeding.
How to use Burn
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
Will it burn fat on its own?
No, and that is the honest answer for every product on this shelf. These compounds help your body process and transport fat; whether that fat gets burned depends on whether there is an energy deficit driving it.
Run at maintenance calories you will see very little. Run alongside a working diet and they support what the diet is already doing.
Why inject it rather than take capsules?
Absorption. Several of these ingredients are poorly absorbed orally, carnitine in particular, where a large share of a swallowed dose never reaches circulation and much of what does is broken down by gut bacteria.
Injecting bypasses all of that. It is the whole argument for this format and for some ingredients it is a genuine one.
How is this different from Lipo Burn or Lipo-C?
Mostly the carnitine. Lipo Burn is the lipotropic three on their own; Lipo-C adds carnitine at 100mg; Burn has the most at 200mg plus ATP.
If you want carnitine, this is the one with the biggest dose. If you want the lipotropics only, Lipo Burn is the simpler and cheaper option.
When should I inject it?
Before fasted cardio is the common choice, since the carnitine transport step matters most when fat is actually being mobilised.
Two to three times a week is the usual frequency rather than daily.
Does it need cycling?
No. None of these ingredients are hormonal and nothing is being suppressed.
Most people run it for the length of a cut and stop when the diet ends.
