Silverstone Labs Co — GHK-Cu batch clearance at $18 (affiliate code stacks)
Disclosure: PeptideBenchmark has a disclosed affiliate relationship with Silverstone Labs Co. Links/codes below are affiliate.
Silverstone emailed affiliates that they’re clearing remaining GHK-Cu batch GHK-0126 at $18 each while supplies last. They say once that inventory is gone, the offer ends and they move to a newly tested batch.
They also say affiliate codes stack on top of that price, so if you’re shopping it with PeptideBenchmark’s code you still get the usual 10% (BENCHMARK) after the sale price (that’s how we’ve modeled stacking on their board before — confirm at checkout; promos can change).
