Frequently asked questions
Which peptide supplier is the cheapest?
It depends on the peptide and dose. Switch the price toggle to 'Per mg' to rank each supplier by cost per milligram after any discount code. Ascension is frequently the lowest cost per mg on core peptides thanks to its sitewide sale pricing, while Limitless Biotech carries the widest selection and the most dose options and delivery forms.
How do the coupon codes work?
Code PEPTIDEDECK gives 50% off at Ascension Peptides — already reflected in the price shown here. At Limitless Biotech, PEPTIDEDECK takes 15% off at checkout, so we show the price with the code applied. SynthLab uses flat sale pricing and needs no code.
Why do prices differ so much for the same peptide?
Suppliers sell different vial sizes and grades. Pick a dose with the dosage pills on each card, and use the 'Per mg' toggle to compare fairly. For Limitless Biotech we use the Premium (lyophilized) grade so it lines up with the lyophilized vials sold by Ascension and SynthLab.
Are these peptides third-party tested?
Each supplier publishes its own testing and certificates of analysis — check the individual product page. All products listed here are sold for research use only and are not for human consumption.
Are the buy links affiliate links?
Yes. PeptideDeck may earn a commission when you buy through these links, at no extra cost to you. Prices and coupon codes are the same as going direct.
