This tastes a lot better than serious mass and is much easier to drink overall. I drank this with reduced fat milk for 3-4 months straight and gained 20 lbs. of course I was also tracking and lifting weights, but this helped a ton to get those extra 800 calories I needed that I couldn’t obtain through meals and a lot of cooking. **Q: I'm most concerned about it causing gas. Any comments?** A: NO Gas with vanilla custard and i give this to my 98 yr old MOTHER who weight 80 LBS as a supplement !! SHE Wd get it cuase shes in a wheelchair- Just finished a 10 lb bag.. DO need to drink WATER cuase HIGH protein can stop u up.. I also add ice cream to it:) tastes great! Good stuff- Doc approved! Shes in GREAT shape + he does Labs on her al the time. **Q: If this is so good, it makes me wonder why it has twice the protein and is $45 cheaper per 10lb bag than Gold Standard - the same company.** A: Which Gold Standard are you looking at? This is a lean weight gainer vs protein vs bulking weight gainer. Sometimes the wholesalers give us deals if we purchase a large amount at a time. Some sellers (myself included) will discount the price in relationship with the "cost" associated with the product I sell. **Q: Which is better for bulk muscle mass: serious mass or pro gainer** A: Serious Mass is a high-calorie gainer with 1,250 calories and 60 grams of protein per serving. PRO Gainer is a high-protein gainer with 60 grams of protein per serving at 650 calories. ## Frequently Bought Together - Optimum Nutrition GS Pro Gainer Weight Gainer Protein Powder, Double Chocolate, 5.09 Pounds (Packaging May Vary) - Optimum Nutrition Micronized Creatine Monohydrate Powder, Unflavored, 120 Servings, 600 Grams (Packaging May Vary) - VELOMIX -2 Pack- 28 oz Protein Shaker Bottles for Protein Mixes - 2x Wire Whisk | Leak Proof Shaker Cups for Protein Shakes | Protein Shaker Bottle Pack | Shakers for Protein Shakes-Black&Transparent --- ## 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.com.pa/products/1262095-optimum-nutrition-gold-standard-pro-gainer-protein-double-chocolate-5](https://www.desertcart.com.pa/products/1262095-optimum-nutrition-gold-standard-pro-gainer-protein-double-chocolate-5) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-22*
