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.

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.

    Bulking Stack review

    Dear All,
    I started off on February the 20th (Three times a day, one tablet from every bottle. In the mornings I wake up at 03:15 to start a 2 hour workout at 04:00. At 03:15 I get some low absorption protein together with my tablets. After my workouts I get again low absorption proteins). So far I must admit my stamina has increased. With some exercises I noticed that I can do them easier than before: with more weights and more reps. I also noticed that I do not feel overtrained or tired after my workouts. I feel I could do more and more. I don’t have time though.
    By the way I am 50 years old and I feel I do exercises with weights as if I was younger.

    Thanks a lot.

    Best Regards,

    It WORKS

    A very good product, overall have been impressed. I have experienced quicker healing and less rest days to get back to the gym and still hit the same muscle time multiple times a week. Back is seeing huge gains as are chest and arms. Looking to get a wider, thicker back and crazy mass is definitely helping me achieve that.
    Looking forward to the cutting stack next!!!!!!


    Good product

    Highly recommended

    I lift pretty heavily, I play competitive sports. This stuff definitely works, I’ve gained a few pounds after taking the pills every day, three times a day. However, I have taken other supplements that have worked pretty much the exact same way and for way cheaper.

    Two months after bulking stack

    I’ve been taking the bulking stack for two months now coupled with Hgh. I took a two year break from body building and lost about everything I work so hard to gain over a six year time period. Now 42 years old my gains are going to be even more challenging. My strength gains have been surprising. I worked out for a month without the product then added it. The gains where almost imediate. The other thing I have noticed is that I don’t have to stick to a super strict diet. I have about six cheat meals a week and still have lost 12 pounds in two months along with putting on size. I definetly love this product and am excited to see where it will take me. Thank you Crazy Mass!

    Good not Great

    I started is stack at 175 benching 250 squatting 335 cleaning 205, after about 6 weeks I’m at about 182 consistently and benching 270 squatting 360 and cleaning 220. It’s hard to tell if the supplements are responsible for this growth or just the hard work and structure of the program I am on. I can say that I do feel and look thicker, I definitely look like I put on more muscle mass but the weight hasn’t come with it. I was looking to bulk to about 190 at least, maybe through the next few weeks of the stack I can get there. I would recommend trying the stack, can’t hurt you to give it a try, haven’t noticed any side affects at all. Don’t expect to just take these pills and get huge though because it doesn’t work that way. No matter what supplements you are taking, you need to be pushing yourself in the gym and eating right to an extent. Good luck.

    Great gains loved the product

    I tried the Crazymass bulking stack for the first time and was surprised how well it worked. I have used multiple brands in the past with some results but nothing like the power and stamina this stack gave me. You do need to be careful and not increase your weights to fast, it will make you feel like you can lift anything. I just received another stack and once I have been off for thirty days I’m going to start another cycle.
