A useful private label mass gainer quote gives you the calorie and macro targets in a defined amount of dry powder, the serving weight, the pack size and the shipping configuration. Start with the customer’s intended serving and packaging budget. A large number on a front label is hard to compare when one quote uses twice as much powder per serving as the other.
Bring both quotes to 100 g
| Illustrative product | Calories per serving | Calories per 100 g | Servings in a 2.4 kg pack |
|---|---|---|---|
| Formula A | 600 kcal in 150 g | 400 kcal | 16 |
| Formula B | 960 kcal in 250 g | 384 kcal | 9.6 before label rounding |
Formula B gives more calories at its larger serving size. Formula A is more calorie-dense in this example. Ask for calories, protein, carbohydrate and fat per 100 g and per proposed serving. Keep powder-only figures separate from a shake prepared with milk or another liquid, which has its own values.
Test the serving that goes on the pack
Write the serving weight in grams and record how many level scoops it takes. Test that amount with the liquid volume you intend to print, using a shaker of realistic size. Record how much shaking it takes, how thick the drink is and whether any powder settles after five minutes. Test a flavored sample and the unflavored base separately when you are considering both. An unflavored base can still taste like its carbohydrate and protein ingredients. For flavors such as chocolate or vanilla, ask for the nutrition panel of the final blend and note any changes to the allergen list.
The Spartacus Gainer 1000 retail listing is a useful example of the distinction between scoop size and serving size. It lists a 50 g scoop and a 300 g serving, so each full serving uses six scoops. Treat the retail listing as a reference for reading a pack. Set your own formula and fill in the commercial brief.
Price the carton as well as the bag
Request packs per carton, gross carton weight and dimensions. Compare delivery cost per bag and per 100 g of sellable powder. A heavier pouch can reduce packaging cost per kilogram while raising a store’s opening order and changing the courier or pallet rate. Ask whether samples use the same mix and fill material as the production pack.
A white label mass gainer can fit if the stock formula reaches your calorie and macro targets at a serving your customers can prepare. If the protein-to-carbohydrate split needs to change, request a custom blend and repeat the same mixing and costing test.
Mass gainer manufacturing, white label and wholesale
For a mass-gainer brand, confirm where the finished blend is made and where its heavy retail packs are filled. Spartacus explains its existing manufacturer and Jordan packing relationship here; obtain supply-chain documents for your own proposed formula rather than treating that page as a guarantee of custom availability.
Send a custom manufacturing brief when you need to change the calorie density, protein source or serving size. For a stock mass gainer packed under your brand, use the white label supplements guide and ask which recipe, flavors and pack formats can be quoted. For finished mass gainer cases to resell, use the wholesale sports nutrition guide and request gross case weight, dimensions and remaining shelf life.
Send your calorie and macro targets, serving weight, flavor or unflavored request, pack size, expected case quantities and destination to Spartacus private label enquiries. If your project is a protein-first shake with a separate calorie target, compare the whey concentrate brief and isolate formula guide.
Keep a private-label gainer quote comparable
A gainer with a large serving can look inexpensive per pack but costly per 100 g or per 500 kcal. Ask for the approved nutrition panel on a 100 g basis and at the exact full serving, including protein, carbohydrate and any added ingredients. The published Spartacus Gainer 1000 pack is an example of an existing product, not a promise that your own formulation will match its calories, price or minimum order. Review the company certificate scopes and request a separate finished-product specification for the proposed brand.
