GH Peak Review

If fitness fans have any one thing in common, it’s probably work ethic.

Say what you like about us, we don’t slack off and ideally we don’t want our supplements to either. This has led to an increase in PM products. These are brands you take before bed which work through the night.

GH Peak from Blue Star Nutraceuticals is one of these. It’s a fat burner which claims to also promote restful sleep and support muscle growth, so by the time you lift your eyelids you’ll be better placed to lift everything else.

GH, as you may have guessed, stands for Growth Hormone.

GH is vital for things like protein synthesis and cell recovery and as with any hormone, poor sleep damages production. So in theory this could be seriously beneficial to performance.

That’s if it works of course. We’re promised:

  • Deeper and more restful sleep
  • Increased fat burning
  • Continued muscle growth
GH Peak

Frustratingly, GH Peak does use a proprietary blend, meaning we’re kept out the loop as far as the dosages of some ingredients. There’s really no excuse for that. Just because it works when our eyes are shut mean we should sleep walk into buying something that doesn’t give us all the facts.

Let’s try and work with the info we’ve got though.

How Does It Work?

At a Glance

  • Arginine Pyroglutamate & L-Lysine supposedly to boost Growth Hormone
  • Ashwaganha to further support GH
  • Melatonin to aid better sleep
  • 5-HTP & Valerian to reduce stress
  • XD Delivery Technology to boost absorption

The Scores

The Scores

Where GH Peak may help you based on its formula is the restful sleep part of the deal.

Melatonin and 5-HTP have both been seen to aid sleep in studies and while there’s little evidence L-lysine and L-arginine together can help GH levels, they can work as a natural anti-anxiety remedy.

That means Ashwagandha is left to cover pretty much everything else we’re promised and at 125mg, that’s just not going to happen.


Another way this product might help with your sleep is by looking at the price tag.

Fainting is a kind of sleep, right? At just under $90 for one bottle, something is definitely at its peak even if it’s not your growth hormone. Normally PM supplements are a little cheaper because they’re an addition to your daytime burner, but clearly not in this case.

We’re not sure GH Peak would be worth it at $45, we know it’s not at almost double that.


For all I’m sceptical, GH Peak actually reviews pretty strongly on sites like Bodybuilding.com.

This user feedback is all we’ve got to go on though, there are no proper testimonials, so we’re lacking a lot of important details. We’re not saying all these positive reports are fake, but a good sleep always puts me in a generous mood, so maybe that’s what’s happening in the case of these users.


Blue Star Nutraceuticals are a well-known, reputable company, so although in this case they seem to have got a little over excited on pricing they’re no con artists.

GH Peak also complies with cGMP regulations so has been produced to the best possible standards.

The proprietary blend, is mainly the sort of pointless delivery system to better absorb GH Peak into your body, to be fair most active ingredients are dosed. That doesn’t change the fact that of its 3 goals it only delivers one, which is not a great trust builder.


Sitting on an A+ from the Better Business Bureau with a wide range of supplements available all round the globe, whatever else we take issue with it’s not Blue Star Nutraceuticals’ professionalism. They score full marks as a company.

All their output is overseen by David Gundermann from the University of Florida. Can’t fault them here.

How Do I Take It?

GH Peak directs you should take 4 capsules once before bed on an empty stomach.

Some reviewers don’t, but I tend to go a little easier on PM supplements that are single serve. Yes one serving will wear off after a few hours, but it is the middle of the night, remember.

Setting your alarm for every 3 hours to top up doesn’t exactly scream restful sleep, eh? So this isn’t ideal but it is at least practical in this case.

Any GH Peak Side Effects?

You’re mostly in the clear with side effects when it comes to the ingredients we know the dosages for. Some of the elements of the XD Delivery system though could potentially be a problem though.

In high doses fumarate for example can cause nausea, diarrhoea or constipation. The blend is only 61mg, but without an exact break down of numbers, we can’t rule anything out.

Where Can I Get It?

You’ll find GH Peak at Bodybuilding.com for $89.99. Not a typo, repeat, not a typo.


Ingredients - In Detail


Arginine can increase nitric oxide levels in the body, helping to improve blood flow and having some knock on effects for energy. The issue with arginine is it’s not typically well absorbed into the body through oral supplementation. Therefore you need large amounts to see any real benefit. Around 6g and above

It is also thought to temporarily increase growth hormone while the body is at rest, especially when paired with Lysine, although research differs on this and is far from conclusive.



Lysine is an amino acid most often paired with vitamin C to boost immunity. When paired with Arginine it may help Growth Hormone in hugh dosages and also help calm anxiety symptoms



A herb used mainly to calm nerves and generally reduce anxiety. Some evidence it slightly reduces the amount of time users take too fall asleep. Any dose over 700mg associated with a morning hangover feeling, though not noted at around 450mg.




This herb is an adaptogen, meaning it help your body better cope with stress, including exercise. In theory this allows you to work out for long and this shift fat the old fashioned way. There has also been small weight loss effects observed but these tend to barely reach statistical signifigance.



5-Hydroxytryptophan is a direct precursor to serotonin, one of the main feel good chemicals in the brain. 5-HTP’s only function is to convert into serotonin, making it one of the most effective natural ways of raising levels and boosting mood.



Melatonin is the hormone released in the brain to induce relaxation and sleep, so obviously supplementing it will have these effects.


Aliases : Ferrous Fumarate

Fumarate is usually used to treat iron deficiency, but some brands believe it increases the bioavailability of nutrients. Can caause nausea and stomach upset if you take too much so it pays to be aware of the exact dose if you're given it.


Panax Ginseng

Aliases : Korean Ginseng, Red Ginseng

Ginseng has a long history of use in traditional medicine and has made the jump to modern use. Nitric oxide means better blood flow and therefore better erections.

Ginseng also has a positively balances blood sugars however, which controls insulin. T levels can be suffer if insulin gets out of balance, so adressing that is welcome.


Astragalus membranaceus

Chinese herb which looks to aid the immune system to a degree and also could benefit healthy kidney function.

However it does this at higher dosages than you'll normally see in supplements, anything from 1.5g to ten times that so we's stop short of saying it's a strong choice.


Black Pepper Extract

Black Pepper Extract

Included for no other reason than it allows the other elements to be better absorbed by the body. This is the more generic version of Bioperine, a patented version.

Alpha Lipoic Acid

Aliases : ALA

Alpha Lipoic Acid may positively affect body weight at high dosages of around 2g, but that's more than your likely to find in most fat burners.

It does have secondary advantages at lower levels however. Around 500mg has been seen to increase blood flow in some cases and also positively influence blood glucose. Both these things may improve energy levels. Not among the MVPs of fat burning, but if the amount is right, not totally useless.


Anything Missing?

Plenty. GH Peak promises to improve sleep, muscle building and fat burning but pretty much forgets to do the last two.

Green tea, green coffee bean and cayenne pepper would significantly increase fat burning ability while the likes of zinc and D-Aspartic Acid are known to enhance GH.


This is certainly not Blue Star Nutraceuticals’ best work. It will help Growth Hormone and fat burning only as far as quality sleep improves both your hormones and metabolism.

A poorly balanced formula that is way, way overpriced means GH Peak just isn’t worth it making this one for the brand’s hardcore fans. True Blues might buy it, but most others should look elsewhere.
