Compare the same amount before comparing the bill
First write down the form, active grams and usable servings. Klean’s approximately 60 servings make its price easy to normalize. NOW’s three sizes and Nutricost’s weight and flavor choices require another selection step. BPN’s 30- and 60-serving options can double the denominator even though the purchase section displays one headline amount.
A recurring discount belongs in a separate column. If you do not want automatic delivery, use the one-time figure even if a subscription panel is visually larger. Then add shipping, tax and any optional protection. A more expensive bottle may last longer, while a low starting price may involve an order setting you do not want.
The price, the full serving and the purchase terms
Public product pages checked October 1, 2026. Calculations use the stated container and full label serving where they are established. Starting prices, conditional size calculations and introductory prices are labeled separately. Tax and unconfirmed delivery costs are excluded.
| Product | Published price | Size / full serving | Usable cost reference | Terms and limits |
|---|---|---|---|---|

| NOW Sports Creatine Monohydrate | $15.99 displayed; size needs confirmation | 8 oz / about 45; 21.2 oz / about 120; 35.2 oz / about 200 servings | If the quote is for 45 servings: about $0.36 each | Multiple sizes share the page; do not apply one displayed price to all containers. |
| Klean Creatine | $34.50 displayed | Approximately 60 servings; 5 g per scoop | Approximately $0.58 per 5 g serving | Selected product price; delivery and any repeat-order terms require checkout confirmation. |

1. CoreAge Rx Strong Suit™
Strong Suit gives this comparison a short ingredient line and a stated 30-serving denominator. Use the starting monthly figure as a reference, then inspect the actual renewal and delivery terms. Its first position is not a mathematical finding that no other powder costs less; the table can show a lower normalized candidate.
Strong Suit names creatine monohydrate as its only ingredient, with 5 g in a scoop and 30 servings per container. The plain, unflavored format gives it a clear amount to compare with other monohydrate powders. Its public page does not supply a sport-certification record or a batch-specific laboratory certificate. Ingredient research cannot establish that this particular bottle produces a greater training result than another correctly labeled product.

2. NOW Sports Creatine Monohydrate
NOW is worth inspecting when the initial outlay matters. Its visible $15.99 and default 45-serving label suggest a conditional low-cost route, but the price must match the actual 8 oz selection. Selecting a larger size without rechecking the number would turn an attractive reference into a misleading calculation.
NOW specifies 5 g in one and a half level teaspoons and no other ingredients. Its page separates three package weights and serving counts, which is valuable when a shop presents several bottles under one headline. The current text exposes $15.99 without a fully locked size selection. Its longer usage directions also differ from a simple one-scoop label. They should be read on the selected package, rather than copied as a recommendation for every shopper.

3. Klean Creatine
Klean is the clearest directly normalized alternative in this set: $34.50 divided by approximately 60 gives about 58 cents for 5 g. That does not include delivery. A shopper who values a simple denominator may prefer this clarity to a seemingly lower quote attached to an unresolved container.
Klean’s readable label lists one approximately 5 g scoop, approximately 60 servings and no other ingredients. That makes it a useful comparison for someone who wants a plain powder rather than a pre-workout mixture. The approximate serving count deserves the same care as a precise-looking price. Its directions are product-specific; their timing language is not proof that another correctly labeled monohydrate powder becomes ineffective at a different time.

4. Nutricost Creatine Monohydrate Powder
Nutricost is a weight-based budget candidate, not a verified cheapest winner. The 500 g and 1 kg choices offer different duration, and flavored selections can have other ingredients. Confirm the exact unflavored weight and full cart before using either 100 or 200 servings in the cost calculation.
Nutricost lists micronized monohydrate, a 5 g serving and 500 g or 1 kg container choices. The readable page also names a flavored selection, so a low number cannot automatically be called the unflavored 500 g price. At 5 g, 500 g would represent 100 servings and 1 kg would represent 200; those are conditional weight calculations, not a verified price pairing. Read the specific flavor’s other ingredients before describing the whole range as additive-free.

5. BPN Creatine Monohydrate
BPN helps illustrate the effect of size and commitment. The one-time $34.99 reference is about $1.17 at 30 servings or 58 cents at 60; the subscription reference is lower but recurring. Choose the container and frequency together rather than assuming the cheapest displayed setting supplies the largest tub.
BPN names Creapure as its monohydrate source and states that the product is NSF Certified for Sport. Its page pairs a 5 g daily serving with two container sizes and several delivery intervals. The displayed prices need a locked serving-count choice before a single cost-per-day figure can be trusted. A subscription may arrive faster than a larger container is used. Quality documentation can justify a purchase question without proving that the brand creates more muscle than other monohydrate.

What would change this shortlist?
A lower delivered quote for an exact 5 g serving could change the cost comparison immediately. A missing certificate, an ingredient you wish to avoid, or a subscription you will not use could change the purchase decision even if the price stays the same.
Keep a screenshot of the selected weight, order setting and total. Prices here are dated public references, not locked offers. There is no independently established market-wide cheapest product in this list, and buying creatine does not replace a sensible training and food plan.
