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... ## Frequently Bought Together - Animal M-Stak - Muscle Builder and Anabolic Mass Gainer Supplement for Bodybuilding - Lean Muscle Growth, Amino Complex and Pre Workout Energy, 21 Packs - Animal Stak – Complete Natural Hormone Booster Supplement with Tribulus – Natural Testosterone Booster for Athletes – Contains Estrogen Blockers – 1 Month Cycle - Animal Test Testosterone Booster for Men - Male Enhancing Supplement Libido Booster for Strength Athletes & Bodybuilders to Increase Stamina, Endurance, Muscle Growth, All-in-One Packs – 21 Day Cycle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/689416758-animal-m-stak-anabolic-mass-gainer-bodybuilding-supplement-21-pill](https://www.desertcart.jp/products/689416758-animal-m-stak-anabolic-mass-gainer-bodybuilding-supplement-21-pill) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-28*
