[GHK-Cu 50mg](/product/ghk-cu) vs 100mg is a format decision, not a quality decision. Both SKUs are lyophilized copper-peptide research presentations of the same catalog identity. The owner page for “what is GHK-Cu” is the compound monograph. This page answers which vial a UAE lab should put on the purchase order.
What the milligram number means
The 50 mg and 100 mg figures are nominal catalog mass printed for inventory and for stock-solution arithmetic. They are not a claim about biological potency, cosmetic outcome, or “strength.”
VaultLabs lists:
If your protocol’s concentration math was written against 50 mg in a stated volume, ordering 100 mg and “using half” only works if someone rewrites the math and the aliquot plan. Use the peptide reconstitution calculator to check the arithmetic. It does not replace a laboratory SOP.
When 50 mg is the cleaner choice
- The study is short, or only one bench will open a vial.
- Your SOP forbids holding opened reconstituted material across many sessions.
- Training labs want a smaller unit so a documentation error costs less material.
- The purchase order must match an existing 50 mg line in the inventory system.
When 100 mg is the cleaner choice
- Several in vitro plates or methods will draw from one qualified lot.
- You want fewer lot numbers in the fridge (one 100 mg lot instead of two 50 mg lots).
- Receiving would rather verify one COA than two.
Fewer lots is a documentation advantage only if the first-open date and aliquot plan are actually written down. A 100 mg vial that sits half-used without a log is not “more efficient.”
Raw powder is a third format, not a bigger vial
GHK-Cu raw 1g and GHK-Cu raw 20g are bulk powder presentations. They belong on GHK-Cu raw powder UAE. Do not treat a 100 mg vial as a substitute for raw powder, or the reverse, without change control.
Documentation does not scale with mass
A 100 mg vial still needs:
- Lot match between label, invoice, and COA
- Portal check in batch verification
- Storage location logged per the storage guide
Purity on the COA describes that lot under the listed method. It does not make 100 mg “higher grade” than 50 mg.
UAE procurement note
Write the SKU, not “GHK-Cu vial.” Accounts payable in institutional settings will reject a 100 mg receipt against a 50 mg PO even when the peptide identity is the same. AED invoicing and research-use language follow the research use policy.
If you are still qualifying the vendor, use the GHK-Cu UAE supplier checklist before you debate vial size.
VaultLabs GHK-Cu is supplied for in vitro research only.
