The Ingredients and How They Work

Raw IGF-1 has an interesting ingredients list that includes some fairly uncommon ingredients, such as Deet Antler Velvet. However, it also has more common ingredients like Tribulus Terrestris and Longjack Extract.

We’ve analyzed all the ingredients to see whether Raw IGF-1 is an effective product overall. See for yourself:

Longjack Extract

Also known as Eurycoma Longifolia, it’s believed to possess aphrodisiac effects. It’s been shown to increase sperm production and quality of erections.

However, there is no evidence in any case studies that it raises the testosterone levels of healthy men.

Tribulus Terrestris 

This is a plant from Ayurveda, from where the roots and fruits are taken to be used as a libido enhancer. It has shown to be effective in increasing sexual well-being and erectile function, but it’s not known exactly why it works.

However, while it has shown to improve sexual well-being and erectile function, it hasn’t been proven to boost testosterone in healthy males.

L-Carnitine 

This is produced in your body, but you can also consume L-Carnitine through food. It’s most commonly used for its ability to boost mental function (memory and reaction time).

However, in terms of T-levels, L-Carinitine hasn’t proven to be effective in raising your testosterone levels.

Colostrum 

This is a form of milk that’s produced in the first few days after giving birth. Colostrum is produced by all mammals, including humans, and promotes growth in babies before they have a fully developed intestinal tract – as it can pass through the intestinal wall for absorption.

However, Colostrum isn’t effective in adults as their bodies break down the growth factors and enzymes that colostrum provides before they can be transported to muscle cells. For this reason, Colostrum isn’t effective in boosting your T-levels.

Diindolylmethane (DIM) 

Also known as DIM, this is a molecule that’s commonly found in broccoli and is believed to be an aromatase inhibitor (prevent testosterone from converting into estrogen).

However, taking too much DIM can lead to an increase in testosterone to estrogen conversion – this is a problem, as it’s part of a proprietary blend, so you don’t know how much DIM you’re consuming.

It’s not worth the risk, especially as there aren’t any studies to actually prove that it improves testosterone production.

Deer Antler Velvet 

This is crushed antler that’s taken from animals that possess antlers (usually deer). It was originally used in traditional Chinese medicine and was believed to have positive effects on health and testosterone levels.

However, studies have shown that it’s ineffective in raising your testosterone.

Fish Oil 

This refers to two kinds of omega-3 fatty acids – eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It’s name comes from the fact that these omega-3 fats are most commonly found in fish.

It can boost your general well-being, but it doesn’t boost your testosterone levels. It’s also worrying because it’s part of a proprietary blend, and as it’s a very low-cost supplement to buy separately, it could be taking up most of the space in the blend – ultimately resulting in you wasting your money on an ineffective testosterone booster.

Also, Fish Oil can cause you side effects such as increased cholesterol if taken in large doses – as it’s part of the proprietary blend, you don’t know the amount of this ingredient is inside Raw IGF-1, so you’re at risk of suffering from this side effect.

Black Pepper Extract 

This is the best ingredient in Raw IGF-1. Although everyone knows Black Pepper as seasoning for food, not many know about the benefits it can provide when supplemented alongside other nutrients.

Black Pepper Extract increases the absorption rate of the other ingredients that it’s consumed with – meaning that the overall effectiveness of a product that contains Black Pepper Extract will be increased.

No ingredients in Raw IGF-1 have shown to be effective in raising your testosterone levels.

Side Effects

The only ingredients in this product that can cause side effects are DIM and Fish Oil. As no-one knows the amount of each individual ingredient contained in Raw IGF-1 thanks to the proprietary blend, you might be more likely to experience side effects if there is a large amount of these ingredients in this product.

Here’s the possible side effects from taking Raw IGF-1:

• Increased testosterone conversion to estrogen (DIM)
• High cholesterol levels (Fish Oil)

Pro’s and Con’s

Pro’s 

• Some ingredients have shown to boost libido and sexual function (Longjack Extract and Tribulus Terrestris)
• Black Pepper Extract is a great addition to any supplement due to its ability to increase the absorption rate of other ingredients it’s consumed with.

Con’s 

• Raw IGF-1 is formed by one proprietary blend – you don’t know the exact amounts of each individual ingredients inside.
• No ingredients have shown to be effective at boosting your testosterone in any scientific or human studies.
• Not good value for money
• Ineffective product

Raw IGF-1 Review Conclusion

Simply put, none of the ingredients in this testosterone booster have proven to actually raise your testosterone levels. The only positive of this product is that two of the ingredients have shown to boost sexual function (Longjack Extract and Tribulus Terrestris), although even these haven’t shown to have any effect on T-levels.

We strongly recommend that you save your money and look for other alternatives on your search for a quality testosterone booster.

The most effective ingredients in raising your testosterone include Vitamin D3 (technically a hormone, it’s proven to improve testosterone levels at a dosage of 3,332IU’s a day), D’Aspartic Acid (an amino acid regulator of testosterone synthesis that’s shown to increase T in healthy men) and Fenugreek (a herb that helps balance glucose levels, which helps to maintain T-levels).
