Shop Bulk Powders at Myprotein

Bulk powders are the foundation of any serious supplement stack — pure, single-ingredient formulas with no fillers, no unnecessary additives, just the raw material you're actually after. From creatine and amino acids to oats and carb powders, this range covers everything from pre-workout fuel to post-session nutrition, giving you full control over what goes into your body and how much.

Whether you're building a custom stack from scratch or topping up a specific ingredient, bulk powders let you do it on your terms. With nearly 20 products across the range — spanning amino acids, carbohydrate sources, pre-workout compounds, protein, and more — there's a powder for every training goal and dietary need.

Who Bulk Powders Are For

Bulk powders are built for people who know exactly what they want from their supplementation. Athletes and gym-goers who prefer to mix their own formulas rather than rely on pre-made blends will find everything they need here — from creatine monohydrate and BCAAs to L-glutamine, citrulline malate, and beta alanine, each available as a standalone ingredient.

They're also a smart choice for anyone who's particular about dosing. When you're working with single ingredients, you decide the serving size, the timing, and the combination. That level of precision appeals to experienced lifters, endurance athletes, and anyone who takes a methodical approach to their nutrition and training.

When to Use Bulk Powders

Timing depends entirely on which powder you're using. Creatine monohydrate — like Impact Creatine, with 3g per serving — is commonly taken daily, either pre- or post-workout, as consistency matters more than precise timing. Carbohydrate powders like 100% Instant Oats or 100% Maltodextrin Carbs are typically used around training, either as a pre-workout fuel source or mixed into a post-session shake alongside protein.

Amino acid powders — including BCAAs, L-glutamine, citrulline malate, and AAKG — are popular both before and during training. Pre-workout compounds like beta alanine are typically taken 20–30 minutes before a session. With single-ingredient powders, you're in control of when and how you take them, making it easy to fit them into whatever routine works for you.

Bulk Powders Benefits

Complete Control Over Your Stack

Single-ingredient formulas mean you know exactly what you're putting into your body. There's no guessing what's in a blend, no unwanted extras — just the ingredient you want, at the dose you choose. That transparency makes it easy to adjust your intake and track what's working.

Proven Performance Ingredients

Creatine monohydrate is one of the most researched ingredients in sports nutrition. At 3g per day, creatine increases physical performance in successive bursts of short-term, high intensity exercise.¹ Impact Creatine and THE Creatine (Creapure®) both deliver this at the proven dose, with THE Creatine using Creapure® — guaranteed 99.99% purity.

Flexible Fuelling With Carbohydrate Powders

100% Instant Oats delivers 62g of carbohydrates per serving, making it a straightforward way to hit carbohydrate targets around training. Protein contributes to the growth and maintenance of muscle mass,² and with 11g of protein per serving, Instant Oats works well as part of a post-workout meal alongside a dedicated protein source.

A Broad Range of Amino Acids

The range covers the full spectrum of popular amino acid powders — BCAAs, L-glutamine, L-tyrosine, L-ornithine HCL, L-carnitine, NAC, and taurine among them. Amino acids are the building blocks of protein, and having individual powders available means you can layer them into your routine without doubling up on ingredients you don't need.

Popular Picks

Impact Creatine — Built for training sessions where output matters, Impact Creatine delivers 3g of creatine monohydrate per serving, which increases physical performance in successive bursts of short-term, high-intensity exercise.

THE Creatine (Creapure®) — For those who won't compromise on quality, THE Creatine is made with Creapure® — the gold standard of creatine monohydrate — at 99.99% purity and 3g per serving.

100% Instant Oats — A straightforward whole-food option for fuelling your day, 100% Instant Oats packs 62g of carbs and 11g of protein per serving, plus a source of fibre to keep things balanced.

FAQs

What are bulk powders?

Bulk powders are single-ingredient supplement formulas — pure compounds sold without additional fillers, flavourings, or blended extras. Rather than buying a pre-formulated product, you get the raw ingredient on its own, which makes it easy to control your dose and combine powders to suit your specific training setup. The range at Myprotein includes creatine, amino acids, carbohydrate sources, protein, and pre-workout compounds.

What bulk powders are available at Myprotein?

There are nearly 20 bulk powder products across the range, covering a wide spread of supplement categories. That includes creatine (Impact Creatine and THE Creatine Creapure®), amino acid powders (BCAAs, L-glutamine, citrulline malate, AAKG, L-carnitine, L-tyrosine, L-ornithine HCL, NAC, taurine, and L-theanine), carbohydrate sources (100% Instant Oats and 100% Maltodextrin Carbs), HMB powder, beta alanine, Impact Whey Protein, Breakfast Smoothie, and Origin Pre-Workout.

Which bulk powder should I choose for performance in the gym?

For high-intensity training, Impact Creatine is a straightforward starting point — it delivers 3g of creatine monohydrate per serving, which is the amount at which creatine increases physical performance in successive bursts of short-term, high intensity exercise.¹ If purity is your priority, THE Creatine (Creapure®) uses Creapure® creatine monohydrate, guaranteed at 99.99% purity.

What is creatine monohydrate and how do I use it?

Creatine monohydrate is one of the most studied ingredients in sports nutrition. It's stored in muscles as phosphocreatine, which plays a role in the rapid resynthesis of ATP during short, explosive efforts. A daily intake of 3g is the established dose at which creatine increases physical performance in successive bursts of short-term, high intensity exercise.¹ It's typically mixed with water and taken once daily — timing matters less than consistency.

What are BCAAs and why do athletes use them?

BCAAs — branched-chain amino acids — are leucine, isoleucine, and valine, three of the nine essential amino acids the body can't produce on its own. They're found naturally in protein-rich foods and are also the most prevalent amino acids in muscle tissue. BCAAs are part of protein, and protein contributes to the growth and maintenance of muscle mass.² Many athletes include BCAA powder in their pre- or intra-workout routine as a convenient way to top up their amino acid intake.

What is beta alanine used for?

Beta alanine is a naturally occurring amino acid that combines with histidine in the body to form carnosine, a compound found in muscle tissue. It's popular among athletes training at high intensities and is typically taken 20–30 minutes before a workout. Beta alanine may cause a harmless tingling sensation on the skin — this is a normal response and is not a sign of any adverse effect.

Can I use bulk powders in Ireland?

Bulk powders from Myprotein are available across Ireland, with the full range shipping directly. Whether you're after creatine, amino acid powders, oats, or carbohydrate supplements, you can order online and have them delivered. Myprotein ships to Ireland, making the full bulk powders range accessible no matter where you're based.

Who develops the bulk powder supplements at Myprotein?

Myprotein's bulk powder range is developed by Myprotein's expert nutritionists, who formulate each product to deliver clean, effective doses of individual ingredients. Every formula is built around the science of each ingredient, with strict quality standards applied throughout production to ensure you're getting exactly what's on the label.

How do bulk powders differ from pre-made supplements?

Pre-made supplements typically combine multiple ingredients in fixed ratios, which makes them convenient but limits your ability to adjust individual doses. Bulk powders give you single ingredients in isolation — so you can take exactly what you need, in the amount that suits your goals, and combine them however works best for your routine. It's a more hands-on approach to supplementation, suited to those who know their stack well.

Are bulk powders suitable for beginners?

Bulk powders work well at any level, though they appeal most to people with a clear idea of what they're looking for. If you're new to supplementation, starting with one or two straightforward products — like creatine monohydrate or a carbohydrate powder such as 100% Instant Oats — is a sensible approach. Each product in the range is a single ingredient, so there's no complexity in understanding what you're taking.

1. Creatine increases physical performance in successive bursts of short-term, high intensity exercise. Daily intake of 3g creatine is required for the beneficial effect.  

2. Protein contributes to the growth and maintenance of muscle mass.
