There is a lot of misinformation surrounding bulking steroids and their legality, how safe they are, the difference between steroids and supplements, and more. At CrazyMass, all our products use all-natural ingredients and formulated to help you get maximum results without the risk of serious health problems, fines, jail time or other consequences.

In addition to the well-documented physical effects of prolonged steroid use in bodybuilders, weightlifters and athletes—such as damage to the liver and cellular adenomas—the scientific community is beginning to understand other negative effects, as well. For instance, researchers from the Department of Physical Medicine and Rehabilitation at Oslo University Hospital in Norway found that, among individuals with a long history of anabolic-androgenic steroid use, there was a decrease in actual brain volume. In other words, there is the potential for steroid users’ brains to become smaller. Our products are a natural and legal replacement for Dianabol, Testosterone, Trenbolone and Deca Durabolin, helping to promote muscle building and fat cutting, as well as quicker recoveries.


Take one pill from each bottle as one serving. You can take up to three servings per day; take each serving with a snack or meal and drink 8-10 large glasses of water a day. Take each serving with a minimum of five hours between servings. If taking three servings per day, your stack should last about four weeks. You can take the product(s) for up to eight weeks before taking ten days off from our muscle building stack. Try to take one serving 30-40 minutes before you work out. We also recommend an ISO-Ignite Protein Shake one hour pre- and post-workout; the shake ignites the ingredients in the muscle-building bulking stack.

We happily accept returns of unopened bottles for up to two weeks after the ship date (minus a small restocking fee). Please email [email protected] for a return authorization number.

Alternative To:

Deca Durabolin, Dianabol, Testosterone, Trenbolone


Deca Durabolin is one of the most popular injectable anabolic steroids available. The legal Deca steroid is used to treat osteoporosis and loss of bone density. What is Deca? Deca Durabolin (Nandrolone) has phenomenal anabolic and androgenic properties which makes it a favorite steroid among bodybuilders. The reason for nandrolone’s popularity is its effectiveness and efficacy in building strength and muscle.

What is Dianabol? Dianabol is the undisputed king of anabolic steroids. The Dianabol steroid was released in the early 1960s and quickly became one of the most popular steroids for bodybuilders and it still is 50 years later. Dbal is extremely effective for rebuilding muscle and is taken orally instead of by injection like many steroids.

Testosterone is one of the best-known hormones produced by the body. Testosterone is primarily a male hormone since men produce far more natural testosterone than women. Test is also responsible for men’s secondary sexual characteristics such as deepening of the voice, the growth of facial hair and increase in muscles.

This hormone is necessary for both men and women in order to keep the body functioning properly. Testosterone and Testosteroxn are primarily concerned with muscular generation.

Bulking and fat cutting with a single steroid, Trenbolone Acetate, what’s not to like? This combination has made Trenbolone one of the most popular anabolic steroids on the planet. Weightlifters use this agricultural steroid to gain mass while losing fat and are willing to risk serious Tren steroid side effects to get these explosive gains that Trenbolone acetate delivers.

    I love this shit. I already had a handle on my nutrition and this just amped up my progress even more! I’ve gone up 5 lbs in two weeks and the pumps are insane. Definitely will be coming back. #crazyfuckinmass

  8. Mark McIntyre

    Happy so far

    I recently purchased the bulking stack,and have been taking now for about 2 weeks @ 2 times a day. I gotta say I’m starting to believe the complete combo(bulking stack) is working as described, but lets not forget hard work and dedication is also required.I have noticed an increase to my energy levels since taking, as it is truly needed for my 3 double days and 2 single days with 2 days off a week.

    Work out for Hours

    Maybe it’s my metabolism, maybe its the difficulty of force feeding over 4000 calories. I am not getting as big as I would hoped after 2 weeks of using the product. HOWEVER, I have noticed that muscle fatigue and soreness is almost absent. I went from working out on average of an hour or so a day to being able to go for over two hours. I typically only stop because it’s getting late or I work myself up an appetite again and am too hungry to continue. Worth the purchase for the energy alone!

    The Stuff works.

    So I was 135 after my football season in early December and I became a gym rat. Hitting the weights nearly twice a day and either this stuff works or it was all me but I’m fairly certain a lot of it was this product. Friends thought I was on roofs including my coach. I went from 130 to 165 by late February and my bench went from 165 to 205. Squat went from 245 to 345. I feel as though that isn’t possible without these products so give it a chance guys!

    Grateful Gains!!!

    I’ve been training for years and have taken many different supplements over that time, but NEVER had results like this. I just got done with a 8 weeks bulking cycle stacked w/HGH. I started feeling the difference after 2 weeks on it and began noticing the gains around week 4. After my 8 weeks cycle, I gained 9lbs of lean muscle mass and completely toned up my overall physique. I would definitely recommend this product to anyone who is serious about their fitness goals. Thanks Crazymass!
