Review: Effective Muscle Building Supplement for Hard Gainers - I recently started using Animal M-Stak, and I am very impressed with the results. As a hard gainer, finding a supplement that effectively supports muscle growth without hormonal components has been challenging, but Animal M-Stak has proven to be a game-changer. First and foremost, the formulation of Animal M-Stak is impressive. The non-hormonal blend is ideal for those of us who want to avoid hormonal supplements but still need a potent formula to help build muscle. The inclusion of the energy complex is a significant plus, providing a much-needed boost during intense workouts. I’ve noticed a substantial increase in my endurance and energy levels, allowing me to push harder and longer in the gym. The convenience of the packs is another highlight. Each dose is pre-packaged, making it easy to take without measuring or mixing. I can simply grab a pack and go, which is perfect for my busy lifestyle. The recommended cycle of three weeks on and one week off is easy to follow, and I’ve seen consistent results with this regimen. In terms of muscle growth, Animal M-Stak has delivered noticeable gains. Within a few weeks of starting the supplement, I saw a significant increase in my muscle mass and strength. The recovery time between workouts has also improved, reducing muscle soreness and allowing for more frequent training sessions. This has been particularly beneficial in breaking through plateaus and achieving new personal bests. Another benefit of Animal M-Stak is the lack of negative side effects. I have not experienced any adverse reactions, which is often a concern with muscle-building supplements. The product has been gentle on my stomach, and the natural ingredients give me confidence in its safety and efficacy. While the taste and size of the pills might be a bit daunting for some, I found them manageable. It’s a small trade-off for the impressive results and benefits the supplement provides. Staying well-hydrated and taking the pills with a meal helps with any potential discomfort. In summary, Animal M-Stak is an excellent muscle-building supplement for hard gainers looking for a non-hormonal option. The energy boost, convenience, and noticeable muscle gains make it a standout product. I highly recommend Animal M-Stak to anyone serious about their muscle-building goals and looking for a reliable and effective supplement to support their journey.

## Questions & Answers

**Q: What is the differance between M-stak and stak???**
A: Think of "M" as maintain  for the gains you made with STAK. Since you are cycling STAK, to take nothing you would see a drop off. With "M" the drop off is minimized.

**Q: Is there a multivitamin equivelant as part of the M-Stak? Or do you recommend still taking a multi with the stak?**
A: No multivite component.  Actually don’t recommend multis for 3 reasons: 1.  Most multis contain improper ratios of vitamins, especially when combined with your diet.  For instance, many contain too much A, & not enough D.  2. because when taken together, some nutrients cancel each other out, such as calcium & iron.  3.  Many people take multis at night, and the B vitamin group can cause insomnia.  Always best to get vitamins from foods or a food based greens powder, or separate nutrients night and day.

**Q: Does this product contain any carbohydrates? If so how many? All artificial sweeteners? Thanks!**
A: I don't remember but all it consist of is a bunch of pills about 10 different pills that you have to take at once. I really didn't like it. I didn't really see any gains from M-stack. I did that the cuts and leaned out. I wouldn't waste my money. Just eat more lift heavy.

**Q: How many pills are in each pack?**
A: It has 21 packs every container...

### ⭐⭐⭐⭐⭐ Very satisfied
*by J***R on October 31, 2025*

Mstak is and does everything it says. I have cycled this several times over the years and just finished one recently. Id say the science has improved even better. I dont take the red. My energy level from the rest makes me not want to leave the gym already. Gains are up and strength and stamina are noticeably improved. Im 58yrs old and mstak has really helped move me over that wall ive been fighting for a couple years. Very impressed. After the cycle the energy drops. Good time to work on cardio and wellness. Cycling and yoga to keep the mind in the gym then hit it again after the break. My physique is very much improved. 10 stars
