We take a look to see if these ingredients, and TT-33, can aid weight loss effectively and safely.

TT-33 Facts

  • Manufactured by iForce Nutrition
  • Unclear how many capsules in bottle- websites mention 60, 90 and 120
  • Seems to be targeted at healthy body builders

TT-33 is designed to be used either on its own or stacked with other products, as desired by the user. As the ingredients used in this product are currently fairly unusual in the weight loss supplement industry, there is little chance that these ingredients (other than vitamin B12) will be present in other weight loss supplements, making it an ideal product to stack for greater effect.

The company does suggest another product that would be good to stack on top of TT-33 is Adipoxil, another product from the iforce Nutrition range. However, stacking multiple diet pills can be an incredibly expensive option, especially in the long run, and it can become complicated to keep track of which pills to take and when.

How to Take iForce Nutrition TT-33

Consume 1 capsule 2-4 times per day, spaced evenly throughout the day. Do not exceed 4 weeks of continuous use.

The iForce nutrition website says each bottle contains 90 capsules, but bottle picture states 120. Even more confusingly, the supplement facts states that each bottle contains 60 servings of 1 capsule per serving: This is frustrating, misleading and confusing, especially as customers have no idea how large the bottle actually is. This makes it very difficult to establish how good this product is in terms of value for money.

iForce Nutrition TT-33 Concerns:

  • Large list of restrictions
  • No money back guarantee or clear returns policy
  • Main ingredients have only been tested in animals

What Does iForce Nutrition TT-33 Claim To Do?

According to the iForce Nutrition website, TT-33 has the following properties:

Metabolic acceleration causes increased BMR! Burn fat all day even at rest! Non-Stimulant thermophoric energy! TT-33 Was specifically engineered with one purpose in mind, increase the actions of the bodies key fat burning mechanisms. This potent thermogenic shift will transform your body from a soft, lipogenic (fat storing) state, to a rock hard, human blast furnace! Don’t settle for jittery stimulants that burn muscle tissue and can cause headaches and anxiety, use the NEXT generation of fat loss, TT-33!

So What Is iForce Nutrition TT-33 and What Are The Ingredients?

The ingredients of iForce Nutrition TT-33 are listed below. The ingredient quantities are listed as well, per capsule. Instructions for use are to take a single capsule 2-4 times a day, as required.

  • Uncoupling Metabolic Adipose Destruction (UMAD) Complex
  • Vitamin B12 (Methylcobalamin) (250mcg 4166%): Vitamin B12 is naturally present in many foods, primarily meat, fish and dairy products. It has several roles, including aiding in releasing energy from consumed food, and keeping the nervous system healthy. It may be that a deficiency hinders weight loss, but taking excess amounts could be, according to the NHS, potentially harmful.
  • 3,3 Diiodo L Thyronine (100mcg)
  • 3,5 Diiodo L Thyronine (50mcg): Studies have indicated that 3,5 Diiodo L Thyronine has a greater effect upon weight loss and fat burning that 3,3 Diiodo L Thyronine. Both Diiodo L Thyronine variations seem to increase the burning of fats in the body, as well as reducing cholesterol levels and triglyceride levels. However, all studies that have been conducted using these hormones have been conducted in rats, not humans, and so it is unclear whether the results would be totally replicated in humans.

So What Does All This Mean?

Vitamin B12 is a water soluble vitamin, and so in most cases the body only absorbs what it needs before expelling the rest of the vitamin from the body in the dieter’s urine. However, some people may continue to absorb large quantities of the vitamin, which can cause side effects. Consuming excess amounts of vitamin B12 is unlikely to significantly boost weight loss. Considering that consumers can take as many as four capsules per day, the quantity of vitamin B12 in this diet pill is unnecessarily excessive.

The other two ingredients are decidedly more potent in aiding weight loss, although currently the only studies we could locate involved animals, rather than being human trials. This means that we have little direct information about how this product may aid weight loss in the body, and have little knowledge of the safety of this product. The only side effects we were able to find information about were reported by consumers on body building forums, suggesting that 3,5-diiodo-L-thyronine and 3,3-diiodo-L-thyronine are still greatly under-researched. The most important thing to remember when using this diet pill is that it should be cycled with a month using the product before taking a month break.

Does iForce Nutrition TT-33 Have Any Side Effects?

Taking excess quantities of vitamin B12 can result in the following side effects: headache, dizziness, diarrhea, indigestion, upset stomach, vomiting, nausea, back pain, swelling, arthritis, anxiety, nervousness and lack of coordination.

Taking 3,5 Diiodo L Thyronine and 3,3 Diiodo L Thyronine could result in decreased thyroid function, which can in turn cause tiredness, weight gain, constipation, aches, dry skin, lifeless hair and feeling cold. Consumers of the individual products have also reported developing severe acne, persistent thirst, a feeling of overheating, shortness of breath, dizziness and occasional heart palpitations.

Any iForce Nutrition TT-33 Reviews From Customers?

There is one customer review of iForce Nutrition TT-33 on, a third party seller of the product.

TT-33 is great. No jittery feeling.

There are more reviews on, which are mostly positive, although one customer felt that they had not seen any changes whilst using the product:

Started using this a couple months ago. I feel like its been a great addition to my stack. Every morning, preworkout, and as a boost during off days: 1 TT-33, 1 Ethitech Yohimbine, and 1 MTS drop factor. Don’t even need coffee after these! :) I really like the clean energy feeling I get. No jitters or anxiety or nasty side effects. While I may not have dropped much weight, Ive dropped A LOT of fat and gained a lot of muscle and sooo much more definition. Definitely wanna keep this stack up.

Definitely noticed more leanness in the midsection after a few weeks of using this. I stacked it with DSX Lean Xtreme and the results are just incredible.

I didn’t see any change.

Finally, on there is a single review:

I bought this to stack with another fat burner and noticed after a week that I lost fat much faster.

So Does iForce Nutrition TT-33 Work?

Whilst many customers appear to be satisfied with the product, there are also some reviews that suggest some customers feel no effects from this weight loss supplement. This product is supposedly not a stimulant, and so can be stacked with other products. It seems that those who were most impressed with the product were actually combining it with other weight loss aids, which makes it difficult to establish how effective it really was.

The company recommend cycling the product, with a month of use before taking a month’s break from the product. This means that it is not really suitable for long term use, especially if customers are relying upon this product too much to boost their weight loss.

Where Can I Buy iForce Nutrition TT-33?

The official manufacturer’s website offering a single bottle for $32.99 plus delivery.

The product is also available from numerous other retail sites. offer a single bottle for $19.99 plus delivery. offer a single bottle of 90 capsules for $23.99 plus delivery.

What About A Guarantee

iForce Nutrition does not appear to offer a money back guarantee, and does not even mention what their returns policy is on the website. As the product is available cheaper elsewhere, customers should shops around, and check the returns policies of other third party retailers before purchasing this product.

Watchdog Verdict

The main ingredients of TT-33 are two variations of diiodo-L-thyronine, which have seemingly only been tested in preliminary animal-based studies. Whilst the ingredients are under-researched and there is no clear information about how they impact human weight loss, they do seem to benefit customers, based upon the reviews. However, this lack of research does concern us.

Consumers have reported side effects, and the company has released a long list of restrictions of who should not consume the product, but this seems to be a safety precaution because of a lack of available information on the product’s safety. Consumers should therefore be certain they are in good health before purchasing the product.

TT-33 does not have a money back guarantee either, making it even more of a risk to purchase this product. Whilst the company claims that this product is ideal to stack with other weight loss aids, this would make weight loss attempts even more expensive in the long run.

We cannot recommend this product, but consumers who are determined to try these ingredients should remember to follow usage instructions closely, and should shop around for a better price and returns policy than the manufacturers offer.

We reject iForce Nutrition TT-33.
