Resources
What am I buying?
Wholesale kits only. Most peptides are 10-vial kits. A few lines, such as some HGH packs and tablet bottles, use the count printed on the product.
Is shipping extra?
No. The listed price already includes shipping.
How do I pay?
Zelle, Cash App, or crypto (USDC or USDT on Ethereum). PayPal is not offered. Zelle and Cash App each add 3%. Cash App is a request we send you — our $cashtag is not shown on the site.
What goes in the payment note?
Only your order number. Do not describe the products.
Can I get a COA?
Yes. Certificates of analysis are available on request. Email support@sterlingresearch.com with your order number and the compound.
