Summit Research Supply vs Stratelabs

Choose Summit Research Supply if…
You want the strongest documentation available on this board. Dual independent testing through ACS Labs and Janoshik is the differentiator — most vendors in this market use one lab, and many use none. Add U.S. fulfilment and a batch COA on every product, and it is the lowest-friction option for a domestic researcher who wants to verify what they received.
Choose Stratelabs if…
Price is your binding constraint and you are willing to request and read the batch documentation yourself. Be clear-eyed that Stratelabs's visible testing is in-house rather than independent, which is weaker evidence.
