Muscle Building Supplements from Dark Labs

Building muscle comes down to consistent training, enough protein and calories, and proper recovery. The right supplements help you stay consistent with all three. This collection brings together the Dark Labs products most often used in size- and strength-focused programmes.

Creatine

Creatine is one of the most researched supplements in sport. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise, a benefit that is obtained with a daily intake of 3 g. Choose between our unflavoured Creatine 500g and the ready-to-mix Alpha Creatine.

Amino acids

L-Citrulline and Beta Alanine are staples in many lifters' routines. They are easy to add to a shake or pre-workout and to dose to your own preference.

Advanced formulas

Turkesterone, Devil Test, Raptor and Built Af are for experienced users who already have training, nutrition and sleep in order and want to add something more to their routine. Read each label carefully and follow the recommended dose.

Getting the most from your supplements

  • Take them consistently. Most products work best as part of a daily routine rather than now and then.
  • Prioritise protein and total calories. Supplements support a good diet but cannot replace one.
  • Sleep and recover. Muscle is built between sessions, not during them.

Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Not suitable for anyone under 18. If you have a medical condition or take medication, speak to your GP first.

Frequently asked questions

What is the best supplement to start with?

For most people, creatine monohydrate. It is affordable, well researched and has an authorised performance claim. See our Creatine collection.

Do I need to cycle creatine?

Most people take creatine daily without cycling. Follow the directions on the label.

Can I combine these with a pre-workout?

Yes. Many customers pair them with a formula from our Pre-Workouts collection. Check the labels to avoid doubling up on the same ingredients.
