Questions
Frequently asked questions
What wellness peptides do you supply?
Our Wellness range includes PT-141 (Bremelanotide), Melanotan II (MT-2), Oxytocin, Thymosin Alpha-1 (TA), LL-37, and Glutathione — covering melanocortin agonists, neuropeptide hormones, immune peptides, and antioxidant compounds.
What is the difference between PT-141 and Melanotan II?
Both are synthetic melanocortin receptor agonists structurally related to alpha-MSH. Melanotan II is a cyclic heptapeptide that acts non-selectively across multiple melanocortin receptor subtypes. PT-141 (Bremelanotide) is a linear analogue derived from Melanotan II with a more selective receptor profile. The two have different molecular weights and CAS numbers.
What purity standard do these compounds meet?
All compounds are verified by HPLC analysis to a minimum purity of ≥98% on a batch-by-batch basis, with a Certificate of Analysis supplied on every order.
Are these compounds GMP certified?
Yes. All compounds in this category are manufactured under GMP and ISO 9001:2015 certified conditions.
Do you offer private label for wellness peptides?
Yes. Custom-branded vials and packaging are available for qualifying wholesale buyers across this category.
What is the minimum order quantity?
Minimum order quantities vary by compound. Contact us with your requirements to discuss MOQs and pricing.
