Instant Knockout vs Alpha Lean 7 Reviews

Here we have two brands that stand out for different reasons. Instant Knockout vs Alpha Lean 7 is going to be a comparison of two companies trying to gain your attention.

From the distinctive fist-shaped bottle of Instant Knockout to the mystery behind the number 7 for Alpha Lean – will it be lucky and work in their favor today?

In reality, appearances and names mean nothing. Sure, it grabs your attention, but after it has done that – what next?

Well, we can tell you what we expect them to do in terms of burning fat, anything less than this will not suffice:

  • Burn fat effectively
  • Be safe
  • Suppress appetite
  • Increase energy

If it can do all of these things then it has a real chance of being victorious today, let’s get to know them a little better first.

Instant Knockout vs Alpha Lean 7: Who Makes These Fat Burner?

Roar Ambition

The company behind Instant Knockout are UK based Roar Ambition.

They have a great reputation for delivering proven and effective supplements but also for customer service.

They have a generous 90-day money back guarantee which really allows you the time to try it on for size. There is also the fact that they review and amend their ingredient profiles regularly. This means you are getting the best possible version at all times.

They deliver directly from the UK and USA and ship the world over.

In terms of endorsements, they have some impressive names. UFC fighter Diego Sanchez uses Instant Knockout to make weight before a bout. Roar Ambition are also the people behind TestoFuel, a T booster used by none other than former Mr. Universe Robby Robinson.

Hard Rock Supplementsalpha-lean-7

The company behind Alpha Lean 7 here.

They are difficult to track down and finding information about them is easier said than done. We can see that they have an online presence on other sites and it seems that they are sold in enough places to be considered legit.

The problem is they look a bit amateurish when they don’t have all their information readily available. Even their logo looks like a child made it.

In terms of products, they have a decent range that includes products called Andro The Giant and Super Mandro.

We can’t find any information regarding money back guarantees and in terms of endorsements, there don’t appear to be any.

Instant Knockout vs Alpha Lean 7 Ingredients

This is where we would usually get to know a product but it is only Instant Knockout that is completely transparent.

Unfortunately, all but one ingredient in Alpha Lean 7 is contained within a proprietary blend. This means their ingredients are all wrapped in this blend with only the total dosage of every ingredient given.

This means it will be difficult to see how effective each ingredient could be, but since the overall blend totals just 467 mg, it is unlikely to be the most potent.

The suggested serving is not ideal for Alpha Lean 7 either, with one capsule taken twice a day meaning the fat burning benefits will not be felt all day long. Compare this to Instant Knockouts 3-4 servings a day and it is a good start for them.

Mutual Ingredients


A staple ingredient in any fat burner and the only ingredient where the dosage is revealed in Alpha Lean 7.

This is important since the energy boost it provides will be very welcome for anyone using a fat burner alongside a lower than usual calorie intake.

The metabolism boost will also work wonders for the user as it uses fat stores for energy and burns it off in the process.

The 200 mg in Alpha Lean 7 will help you but the 350 mg spread across 4 servings in Instant Knockout is optimal.

Green Tea Extract

As good as it gets for fat burning, a very important ingredient.

This is so good because it works in two ways to burn fat.  It is a proven thermogenic meaning it will heat up your body inside, causing it to burn fat to cool itself down. It also helps to maximize the fat burning benefits of exercise.

So, it helps to burn fat while you rest, and when you workout.

Alpha Lean 7 has this in their proprietary blend. Since the total blend is under 500 mg, and Instant Knockout contains 500 mg of Green Tea Extract, you can see which is going to really get you burning fat here.

Individual Ingredients

Instant Knockout

Cayenne Pepper

Another great ingredient from Instant Knockout, this works on two levels.

Again, it is another proven thermogenic, you really can’t get too many of them in a fat burner. On top of this, it is an effective appetite suppressant. It swells in the stomach, causing you to feel full and therefore less likely to reach for a snack in between meals.

The 100 mg is all you need to get the benefits.


Another great appetite suppressant.

This dietary fiber is another that swells in your stomach, absorbing water at the same time. This helps with water retention and stopping you from taking on more calories. Especially good when you have worked hard to get rid of them.

The 500 mg shows just how committed they are to getting you shredded.

Black Pepper Extract

Another good ingredient and although this isn’t a direct fat burner, it is a nice addition to any supplement.

This is because it helps to maximize the benefits of the other ingredient by enhancing their capabilities. This is especially good when you are using a supplement that has as many great ingredients as Instant Knockout.

The 10 mg is a great amount once again.

Alpha Lean 7


A bit of a let down really.

If you think the best way of losing weight is by urinating a lot then this diuretic is what you are looking for.

In our opinion, this isn’t the best way to approach this and in terms of actually burning fat, it has little evidence to back it up.

Still, it is part of the proprietary blend meaning we have no idea if it will be useful here anyway.

Synephrine HCL

It goes from bad to worse really as this ingredient might be a decent thermogenic and energy booster but not without its dangers.

Often known as bitter orange, it works in a similar way to ephedra which has been banned by the FDA that is linked to strokes and heart attacks. There is definitely more research required to warrant its place in a supplement.

Rauwolfia Vomitoria

Since it works in a similar way to Yohimbine which is known to cause side effects this is another ingredient we would stay clear of.

It might have a positive effect on your cognition but really it is another that is best saved until more research is completed.

Instant Knockout vs Alpha Lean 7 Side Effects

Instant Knockout does not contain anything that should concern you.

Alpha Lean 7 contains Syntherine and Rauwolfia Vomitoria which work similarly to other ingredients that are linked to causing side effects such as heart attack and strokes. For us, we would like to see more evidence warranting their place and to ensure their safety.
