Rating: 4 (out of 5)

UPDATED: December 21st, 2023

Welcome to this review of the CrazyBulk Trenorol product (formerly known as TBal75). This “legal steroid” is a muscle building supplement that is designed to really accelerate gaining muscle size yes but its main core competency is as an anabolic cutting agent. In is designed to help weight trainers that chiseled, cut look.

CrazyBulk offers a full line of bodybuilding supplements, or more accurately, steroid alternatives, but does it work? Well, that’s what this review is all about.

Product Quality

In 2010, the US FDA began requiring all supplement companies to meet current good manufacturing practices (cGMP or GMP). This was due to such massive fraud in the supplement industry at large. The deliberate lying of ingredients, inferior ingredients and wild, extravagant claims made by companies brought forth much consumer irritation and rightly so. So, this is a good step. The problem is, though, that they don’t enforce the requirements of the yearly audits!

They leave it to companies to self-regulate. Fortunately for us the consumer in the Internet Age, we can research a lot about a company so many companies like Optimum, Douglas Labs, Xtend-Life and others are voluntarily meeting these standards and in some cases exceeding them. The agencies that conduct the yearly audits are:

  • NNFA (Nаtіоnаl Nutritional Food Aѕѕосіаtіоn)
  • NPA (Natural Products Association)
  • USP (United States Pharmacopoeia)
  • NSF International (National Sanitation Foundation)
  • WHO (World Health Organization)
  • TGA (Therapeutic Goods Association)

The good thing for CrazyBulk as far as quality is concerned is that they produce their products in a GMP-compliant facility and that bodes very well for the consumer. This is a high mark as the yearly audits are quite rigorous.

Trenorol Product Features & Benefits

The products offered by CrazyBulk are not weight training supplements per se. They are marketed quite openly as “legal steroids” without the side effects. The product, the company says, is to incur, “Mаѕѕ muѕсlе gains, ѕtrеngth, physical conditioning, bulking & сuttіng.”

The company says, “Trenorol rе-сrеаtеѕ the аwеѕоmе effects оf Trеnbоlоnе, рrоbаblу thе most vеrѕаtіlе ѕtеrоіd оf all time duе tо іtѕ аmаzіng аnаbоlіс аnd аndrоgеnіс еffесtѕ. Nіtrоgеn rеtеntіоn аnd rеd blооd cell рrоduсtіоn is іnсrеаѕеd and fаt burnіng іѕ accelerated. Exресt іmmеnѕе muѕсlе gаіnѕ, аwеѕоmе strength аnd роwеr, аmаzіng рhуѕісаl соndіtіоnіng, fast hеаlіng and еvеrуthіng еlѕе іn bеtwееn. Use іt fоr bulking оr cutting; whаtеvеr уоu wаnt, TBаl dеlіvеrѕ – fаѕt.”

CrazyBulk TBal75 before and afterHeady claims to be sure. They say it’s possible due to the enhanced biochemistry of the product. The company says that it’s more potent than testosterone as the аndrоgеnіс effects оf Trenorol causes one’s muscle tissue to retain mоrе nіtrоgеn, оnе оf thе buіldіng blосkѕ of рrоtеіn, which in turn leads to muscle gаіnѕ. Rеd blооd сеll рrоduсtіоn іѕ increased and thus роwеrіng mоrе oxygen tо your muѕсlеѕ durіng уоur wоrkоutѕ, gіvіng уоu increased strength аnd роwеr. TBаl gіvеѕ its users “аn еxсеllеnt hard, defined look,” says CrazyBulk.

What about serving size? One tablet is approximately (75mg) with 90 tablets in the bottle. The company says to ingest one (1) tablet three (3) times daily with meals, even on non-workout days. On workout days, they say users should take 30-45 minutes before working out.
 For best results, Crazy Bulk says to supplement with it for at least two months with the workout period being two months working out or on and two weeks off — that is the recommended process, the company says.

Trenorol Side Effects

The manufacturer CrazyBulk says that this product is perfectly safe without side effects to the liver, blood, kidneys or any other part of the human body. I’d like to see more discussion on that with CrazyBulk, but one thing is that if it is made (and it is) in a GMP-compliant facility, that bodes well for banned ingredients do not pass the GMP audit.


As with all CrazyBulk products, if you buy two, you get one free. It is a product that is part of their various bodybuilding stacks but is also sold as a standalone product. It sells for $61.99 USD (United States Dollar) marked down from $85.00. They say also that you can buy three for the price of two.


The guarantee is only from seven days. Some think it should be longer as do I. That said, if it works as advertised, most will not care about the guarantee.

Trenorol Customer Reviews

This product, and the company in general, is still getting “its legs.” Still, there are a goodly number of customer testimonials or reviews out there. Here are a few:

Where Can I Buy It?

CrazyBulk Trenorol BottleYou can buy it here, but you are free to choose. So, what’s the verdict? This product, whether used as a standalone product or as part of a stack, this product appears to work — and work well. It is made in a GMP-compliant facility and the shipping of it is free to U.S. and U.K. customers. The one concern some have with it is that it’s not a nutritional supplement but a legal steroid without the crazy side effects.

It does appear to be safe, though. Another argument is that the guarantee is not that long but if it works, that short length is mitigated in the final analysis if it works, most bodybuilders and weight training aficionados won’t care. I give it a 4.2 out of 5.00, but I will change it after it is in the marketplace longer. I hope this review of the CrazyBulk Trenorol product has been helpful to you.
