I have been hesitant to roll out any affiliate codes on my guide and website or for this account. I know I am capable of remaining neutral but am very aware that affiliations for peptide vendors can seem that I am showing favoritism or glossing over flaws that a given company may have. I have been given an affiliate code from Crush and Blank but have not yet posted them. I’m still building out my site and want to do this carefully. For now, the only affiliate codes I am broadcasting will be with labs. I was very impressed with the quality @ILSLabs showed with the testing they performed for Crush. For anyone that has purchased untested research peptides and need to have quality tested performed, use code PEPGUIDE for a discount.

“How long is this good after I reconstitute it?” The most asked question in peptides. Every brand tells researchers “use within 30 days.” None of them can prove it. ILS is proud to be the first to launch Reconstitution Stability testing as a standard service- built on USP <1150> and ICH Q1A accelerated stability guidelines. One test. One COA. A real, data-backed beyond-use date your customers can trust. The brands that lead with data win the trust. Stop guessing. Start proving. Visit ils-lab.com/register to get started!

Other labs: 'email us for a quote' Also other labs: replies 4 days later We built a portal instead. Enter your products, select your tests, print the packing slip, ship. No back and forth.
