How to Choose a Peptide

Step 1 — Start with the goal, not the compound

Beginners often start with a compound name they saw online and work backwards. Flip it. Start with the research area you care about — recovery, skin, sleep, cognition, energy — and let that narrow the field.

Our shop is organised exactly this way, by goal, so you can see which compounds are most studied for a given area before you learn a single abbreviation.

Step 2 — Weigh the evidence tier

Not all peptides are equal on evidence. A rough three-tier way to think about it:

• Well-studied — substantial published research (e.g. GHK-Cu for skin, BPC-157 and TB-500 for tissue-repair research).
• Promising but early — encouraging findings, smaller body of evidence.
• Speculative — interesting theory, little direct data.

A sensible newcomer leans toward the better-studied end and reads the actual research overview rather than marketing copy.

Step 3 — Verify quality every time

Whatever you choose, the quality checklist doesn’t change: HPLC-verified purity, a batch Certificate of Analysis, correct sequence, and proper cold-chain storage and shipping. A well-chosen compound at poor quality is a poor choice.

This step is non-negotiable and it’s where a lot of cheap sources fall down. If purity and a CoA aren’t available, walk away.

Step 4 — Get the practical details right

Finally, the boring-but-important logistics: understand storage, use accurate measurement (our reconstitution calculator does the maths), and read the research overview for the specific compound so you know what’s actually documented.

If you’d rather not assemble a protocol yourself, curated research stacks group commonly paired compounds together — a lower-friction starting point that still ships with full verification.
