What is Testabolan CYP?

By HighYa Research Team
Published on: Jan 2, 2017

Formulated by iForce Nutrition, Testabolan CYP is a performance-enhancing supplement that promises to increase muscle mass, cut recovery time, enhance sexual stamina, and deliver sharper mental focus.

Testabolan CYP claims to accomplish this in several different ways. First, the manufacturer tells us it promotes protein synthesis and reduces muscle catabolism, which helps you quickly gain mass and strength.

Furthermore, the supplement’s cutting-edge nutraceuticals claim to support healthy levels of androgen-binding protein and sex hormone binding globulin, thereby boosting the amount of free testosterone circulating in your blood.

Finally, we’re told that Testabolan CYP will boost four different growth factors and will even reduce the stress hormone cortisol, adding up to mind-blowing results that can “reinvent your body.”

All you have to do is take 2 capsules of Testabolan CYP in the morning with a meal and again at dinner. The company recommends using the supplement for no more than 12 weeks, followed by a 4-week off period.

What’s the deal here? Is Testabolan CYP some kind of legal steroid, or just another in a long line of supplements that promise to turn you into a raging beast of a man, while delivering little value for the money? Is it safe?

That’s exactly what we’ll help you answer by detailing what we learned during our research.

The Basics of Building Muscle

The Testabolan CYP website tosses around potentially confusing scientific terms like they’re horseshoes, so let’s take a quick moment to de-mystify them:

Muscle Function

At the microscopic level, your muscles are made up of fibers, which are long, cylindrical cells.

These fibers are also what cause your muscle to contract; slow-twitch fibers don’t fatigue easily but also contract more slowly than fast-twitch fibers, which tend to fatigue quickly.

Whenever you work out, these muscle fibers become damaged. Your body then works to repair or replace these fibers, which gradually builds muscle strength and size.

In order to repair (or even maintain) your muscles, though, your body requires amino acids, which act as the basic building blocks. Your body primarily obtains these amino acids from protein, and Testabolan CYP promises to help synthesize, or break down, any protein you consume to make it more available for your muscles to utilize.

On the other hand, if you haven’t consumed enough protein and your muscles don’t contain enough of these essential amino acids, it will enter a catabolic state. In other words, it will start breaking down muscle to use as a fuel source.

Similarly, cortisol is a catabolic hormone released when you’re stressed, which is something Testabolan CYP claims to reduce.

What Are Growth Factors?

In contrast to a catabolic hormone like cortisol, growth factors are naturally occurring substances capable of stimulating growth at the cellular level.

While there are hundreds of different growth factor classes, Testabolan CYP promises to increase the presence of four specific ones:

  • Insulin-like growth factor (IGF) – Proteins very similar to insulin that help increase muscle mass, induce protein synthesis, and prevent muscle mass from decreasing.
  • Nerve growth factor (NGF) – Primarily affects the growth and maintenance of neurons, or nerve cells.
  • Fibroblast growth factor (FGF) – A multifunctional protein that helps encourage cell division.
  • Epidermal growth factor (EGF) – Like FGF, this growth factor helps stimulate cell growth.

The Role of Testosterone

Similar to growth factors, testosterone is a hormone that, among other things, can help increase muscle size and strength.

Not all testosterone in the body is equal, though. Sex hormone-binding globulin (SHBG) and androgen-binding protein (ABP) render testosterone inactive; also referred to as “bound.”

As a result, only “free” (or unbound) testosterone is biologically active and available to help increase muscle mass and strength. And it’s this free testosterone that Testabolan CYP claims to boost.

Exactly what ingredients does the supplement use to accomplish this?

Are Testabolan CYP’s Ingredients Effective?

According to their label, Testabolan CYP contains the following ingredients:

  • Free Testosterone Matrix 1,420mg
  • Acetyl-L-Carnitine 1,000mg
  • 3,4-Divanillyltetrahydrofuran 400mg
  • Naringin 20mg

Acetyl-l-carnitine is an amino acid produced naturally by the body that helps promote muscle movement and brain function.

As a result, WebMD indicates that supplementation can help improve memory, reduce nerve pain, treat Peyronie’s disease and male infertility, address symptoms of age-related testosterone deficiency, and boost blood flow to the brain.

Regarding testosterone, 2 grams of acetyl-l-carnitine daily may address sexual dysfunction, depression, and fatigue as well as testosterone therapy. At 1,000mg twice daily, Testabolan CYP seems to provide this necessary amount.

3,4-divanillyltetrahydrofuran is a chemical compound found in some plants (known as lignans) that has been shown to reduce the ability for sex hormone-binding globulin to do its job, thereby boosting free testosterone levels.

There doesn’t seem to be a lot of clinical evidence supporting 3,4-divanillyltetrahydrofuran’s ability to meaningfully increase free testosterone in humans, though.

Finally, naringin is a chemical compound naturally found in citrus fruits and especially in grapefruit.

It’s often included in supplements like Testabolan CYP to boost the absorption of other ingredients, especially acetyl-l-carnitine, although authoritative websites indicate that most clinical evidence was obtained in Petri dishes or animals; not humans.

Will these ingredients cause any side effects?

Potential Testabolan CYP Side Effects

According to authoritative websites, most of us probably won’t experience any side effects from Testabolan CYP’s ingredients. And if we do, it likely won’t be any worse than mild digestive upset.

3,4-divanillyltetrahydrofuran is derived from stinging nettle, which may cause sweating.

Naringin is derived from grapefruit, which could potentially interact negatively with a long list of medications, including dextromethorphan, estrogen, and medications for high blood pressure and those for lowering cholesterol.

Potential side effects aside, how much will you pay for a bottle of Testabolan CYP?

How Much Does Testabolan CYP Cost?

What you’ll pay for Testabolan CYP wholly depends on where it’s purchased.

For example, if bought through one of the manufacturer’s landing pages, a single bottle (60 capsules) will only cost you $4.99 S&H. However, 14 days after placing your order, you’ll be charged the full price of $89.95.

On top of this, you’ll be enrolled in the company’s recurring shipping program, which means you’ll continue receiving a new bottle of Testabolan CYP once per month and charged $89.95 plus $4.99 S&H each time.

However, if purchased directly through iForce’s website, you’ll pay $74.99 plus a $7 flat rate shipping charge, although it doesn’t appear you’ll be signed up for any kind of autoship program.

If purchased through the company, Testabolan CYP comes with a 30-day refund policy, less S&H. Keep in mind that this only applies to unopened bottles.

To request a refund or cancel your autoship enrollment, you’ll need to contact customer support at 877-356-6092 or support@hghproboost.com.

Pro tip: We also found Testabolan CYP sold on Bodybuilding.com at a much lower price of $39.99—again, without any autoship enrollment.

What Are Customers Saying In Their Testabolan CYP Reviews?

On Bodybuilding.com, Testabolan CYP had an average 8.6 rating based on 14 customer reviews. Common compliments referenced increased libido, increased energy, sizeable muscle gains, better sleep, and improved workouts.

On the other hand, some customers complained that they didn’t experience any benefits (very common among any nutritional supplement), increased aggression, and insomnia.

From a company perspective, Testabolan CYP is brought to you by iForce Nutrition (part of the Hi-Tech Pharmaceuticals family of brands), who, among others, makes another supplement named ThermOxyn.

Neither company was listed with the Better Business Bureau at the time of our research.

Pro tip: When searching online for Testabolan CYP reviews, we encountered another supplement bearing the same name that was sold in the mid-2000s, which contained 5-alpha androstanediol, a steroid prohormone that has since been banned.

By all appearances, this older version of Testabolan CYP has no relationship to the current iForce version.

Will Testabolan CYP Turn You Into a Beast?

Compared to many of the other testosterone boosting supplements and muscle growth products the HighYa team has reviewed over the years, including Elite Test 360, Bio Testosterone XR, and Beyond Human Testosterone, the clinical evidence seems to support Testabolan CYP’s ingredients—at least to an extent.

For example, 3,4-divanillyltetrahydrofuran may help boost free testosterone in vitro and animals, although authoritative websites report little-to-no clinical evidence supporting its efficacy in humans.

Additionally, acetyl-l-carnitine may help address some side effects related to low testosterone—even as effectively as testosterone therapy in some cases—although it doesn’t appear to actually boost free testosterone in the body.

Perhaps the biggest stumbling block related to Testabolan CYP, though, is its price, since you can purchase a standalone acetyl-l-carnitine supplement online for as little as $10, while some stinging nettle extracts (containing 3,4-divanillyltetrahydrofuran) can be found for even less.

Given this, it’s not clear—even at $39.99 through Bodybuilding.com—that Testabolan CYP is necessarily worth the higher price.

And it becomes even less clear when you factor in the $80+ price tag directly through iForce Nutrition, the fact that you’ll be signed up for recurring monthly shipments, and that refunds are only available on unopened bottles.

    Testabolan, don't waste your money

    • Columbus, OH,

    Their 14-day trial was not openly disclosed on the mobile site. Taking product as "suggested"? There have been little to no noticeable results after 16 days.

    Testabolan CYP

    The product itself is more than questionable, but it's the sales program that is a rip-off.

    Buyer beware; when you get a trial, they automatically add another product that is more expensive, and then they start charging your credit card $89 a month (per bottle that they send you). They also sent me Megadren, so they charged me more than $180, which I wasn't aware that they were going to do.

    The whole thing is a rip-off. To charge unsuspecting people more than $180 before they realize what's going on, which usually isn't until they get their credit card statement. I doubt anyone actually uses this product on an ongoing basis

    Not HAPPY!

    • Branford, CT,

    This is such a scam!

    I was first told it was free and I only had to pay postage, but I was charged twice for the postage of one package, and then four days later, I was charged $87.98 and $89.95 for the "FREE" products! I sent them back after being told at first that I could not but spent an hour on the phone fighting this. I paid the return postage and was given a refund for one product, but not the other! I have since called countless times, emailed them twice, and finally got a hold of someone who said I have to wait yet again for someone to call me back.

    They took my money without my permission well over a month ago! I have wasted hours of my time and am yet to be refunded my money. It's a scam; don't buy it!

    Deceptive marketing, questionable results and poor customer satisfaction

    • South Carolina,
    • May 10, 2017
    • Verified Reviewer

    Impressive deceptive marketing without total disclosure of business practices.

    The free bottle is not free if you keep it. The first billing, if not canceled, is the difference between the $4.99 shipping and the balance of the product cost, which is almost a total of $95. This amount will be billed to you every month if you don't fight with them to cancel it. Even at that, while you are protesting the charges to your credit card, they continue to ship product and bill you. Getting these charges reversed is a nightmare.

    While the initial hook is to get you to try it for the cost of shipping only, they get you by saying that if you don't cancel within the 14-day time frame, you will continue to be charged. I might add that this stipulation is not obviously stated. The problem is trying to get them to cancel the order. I was told when I called to cancel that it was done, but I continued to receive product and being billed. They will not provide an address for me to ship back the unwanted product and resist refunding my money.

    My personal results included difficulty sleeping and stomach nausea. No other noticeable physical effects. I am 62 years old, and I do not take any other medications.

    I am fine with paying the initial $4.99 shipping for the trial bottle, which is what I asked for, but I am fighting to get a complete refund for the three other charges to my account.

    Any other legitimate business will provide a refund for the unused product when it is returned, but this company has an aversion to doing that, plus charging you the full amount for something after you are told is a free sample for only the cost of shipping, which is a deceptive lie.

    The best advice is if you must try this, pay for the first trial using a type of PayPal account which prevents them from continuing to charge your account, which is the safest way to protect yourself.

    Do not buy!

    This company will screw you as much as the day is long. I'm out over $200 from these thieves! Don't even try to get a refund because they will have you repeat yourself numerous times while simultaneously trying to up sell you. They are not even taking your call from the US either. You can't even find JM Labs of Englewood, Colorado. This is only the tip of the iceberg of how angry I am.

    Do not buy this product! Hopefully, I can help someone from some major frustration. They will not be in business long either. The guy who has endorsed the product from ESPN should be in small claims court on a weekly basis! Thanks for listening.

    Buyer beware, total scam

    • Lafayette, IN,

    • Verified Reviewer

    BUYER BEWARE, this is a complete scam. Your free trial, which you get for paying shipping and handling, turns into $180 a month if not canceled within 14 days, which nowhere did it say that when ordering the "free" trial. I have already spent two hours on the phone to get my money back, and they say they can't because I already have the product in my hands. Luckily my wife caught the charge so I could cancel all product shipment from this point forward. To make a long story short, my "free trial" ended up costing me $220.

    When you order the sample be sure to cancel on the 13th day or they will charge you $89.95 and will not send you anything else, but will tell you it's on the way. I called them back today to ask about my shipment, and they said I was full of crap and that I didn't know what I was talking about, but I have the charges on my bank statement.

    Complete scam

    If you sign up for the "free trial just pay $4.99 shipping," you are also automatically enrolled in an auto-ship. So unless you call and cancel, you'll be charged $90 a month plus shipping for this BS testosterone booster. The website conveniently only states this fact in the fine print which most people will probably never see or read.

    It appeared on my credit card statement as "Maggie May." When I called my credit company, they said it's a skincare company that's apparently affiliated with these people? Sounded so sketchy to me.

    When I called to cancel, the customer service rep kept offering me additional options for extending my trial and buying more supplements! Ridiculous. I said point blank "No, I'm canceling any subscriptions and auto enrollments" and still she persisted. Hopefully, she actually canceled my subscription.

    Do yourself a favor and stay away from Testabolan CYP and their hghproboost.com website.

    Total rip off

    I wish I had the reviews prior to ordering. I had the same experience; automatically enrolled in the monthly program after 14 days and still waiting on trying to get back my money.

    Testabolan CYP and Megadren were grouped together. I was willing to try but saw no results and wanted to cancel. I got some of my money back but am still waiting on about $150 in refunds. I have called them back 6 times, and each time they said to give them a little more time to issue the refund. I doubt it will ever come.

    To make matters worse, apparently, they auto-enrolled me in in a medical concierge service 6 months after the initial order. APPARENTLY, that was also the very fine print! I just got off the phone with these people, so I'll see if that refund ever arrives.

    Do not deal with these companies under any circumstances.
