The $100 lab bench

The bench everyone builds eventually — a milligram scale, a capsule machine, jars and desiccant. The threads converged on this kit years ago; it costs less than two tubs of branded pre-workout.

Ask r/Supplements what to buy first and the answer is always the same list: a 0.001 g scale for the micro doses, a kitchen scale for the gram stuff, and airtight jars so it all survives the humidity. This page is that consensus, priced out.

The workflow

  1. 01

    Source

    Buy single-ingredient bulk powder from a vendor that publishes a batch COA - identity, purity, heavy metals, microbes.

  2. 02

    Weigh

    Milligram scale for anything under a gram, kitchen scale above it. Scoops move powder; they don't measure it - density varies batch to batch.

  3. 03

    Mix

    Micro-dose actives go in by geometric dilution - blend the small dose into an equal part of base, then keep doubling until uniform.

  4. 04

    Portion

    Weigh per serving, or encapsulate, or batch-mix the gram-scale ingredients. Never batch-mix caffeine into a tub.

  5. 05

    Store

    Airtight jar, desiccant pack, dark and cool. Citrulline malate and glycerol cake hard in humidity.

  6. 06

    Log

    Label every jar with contents, batch date and the per-scoop math. Start under target dose and document.

Reading a vendor

  • Batch-specific COA from an independent lab - not the vendor's own letterhead
  • cGMP facility; NSF or Informed Sport certification if you compete
  • Full label disclosure - the vendor's own products shouldn't use prop blends either
  • Community standing - r/Supplements and r/Nootropics keep running vendor lists
  • Skip AliExpress, eBay and third-party marketplace sellers - the counterfeit history is documented

What the threads wish they'd known

  • Buy the milligram scale before the powder — the people who did it backwards are the cautionary tales
  • Label jars the day they arrive; 'I'll remember which is which' is how the legendary mix-ups start
  • Glycerol and citrulline malate cake fast — desiccant isn't optional in humid climates
  • Start every new ingredient under the community dose and titrate up — nobody regrets going slow

The legal line

Mixing for yourself is unregulated - you're a consumer preparing food-adjacent powders. The moment you sell a blend you manufactured, you're a supplement producer: FDA 21 CFR Part 111 cGMPs, facility registration, Supplement Facts labeling, adverse-event reporting. In Canada, commercial sale needs an NPN product licence.
