The products don’t work
The products don’t work. I’ve been using their retatrutide, mk2 and ghk-cu, with recommended dosing for a month and a half. Not seen any difference with any of them. I’ve used reta before off a different supplier with half the dose and seen a huge difference then, but this now hasn’t reduced my appetite in the slightest

Hi Tom, thank you for your honest review and we're truly sorry to hear this.
We want to be transparent - we did identify issues with a previous batch and received mixed feedback from customers. We immediately paused all sales and moved to a new premium supplier, which we should have done sooner. We hold our hands up.
We've reached out to you directly via email and would love the opportunity to send you replacements from our new batch completely on us, so you can experience the difference. Our latest batches have been independently verified at 99.9% purity by PeptideVerify - results are live at https://biosupplyuk.com/pages/coa.
Please do check your inbox and we'll make this right for you.
