Research Peptides
Every compound, stack, delivery format and supply we manufacture, grouped by research category. All material is synthesized in a US cGMP-compliant facility at 99%+ HPLC purity with lot-matched certificates of analysis.
Core Heavyweights
The highest-demand research compounds: metabolic agonists, repair peptides and copper peptides.
Retatrutide
Retatrutide is a triple receptor agonist acting at the GIP, GLP-1 and glucagon receptors. Every PX1 Research lot is synthesized in a US cGMP-compliant facility, assayed by HPLC and LC-MS, and published with a lot-matched certificate of analysis.
ExploreTirzepatide
Tirzepatide is a dual incretin agonist targeting both the GIP and GLP-1 receptors. PX1 Research manufactures tirzepatide domestically under cGMP-compliant controls with full analytical release testing.
ExploreBPC-157
BPC-157 is a synthetic pentadecapeptide sequence derived from a protein found in gastric juice. It is one of the most widely studied research peptides in tissue repair and angiogenesis literature.
ExploreGHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) studied extensively for extracellular matrix remodelling, collagen synthesis and antioxidant signalling.
ExploreSynergistic Stacks
Pre-blended multi-compound research protocols formulated for combined mechanisms.
Wolverine Stack
The Wolverine stack is a pre-mixed 10mg research vial containing 5mg BPC-157 and 5mg TB-500 (Thymosin Beta-4 fragment). It is the most requested recovery blend in the tissue-repair literature.
ExploreGLOW Protocol
GLOW is a cosmetic-science research blend built around GHK-Cu, paired with repair peptides for microvascular support. It is the most searched stack in skin-remodelling and longevity research.
ExploreAdvanced Novel Form Factors
Needle-free delivery: sublingual dissolving strips and metered intranasal formulations.
Sublingual Peptide Strips
Sublingual strips dissolve under the tongue against a highly vascularised mucosal bed, removing the need for reconstitution or a syringe. PX1 strips use a bio-adhesive polymer matrix with precise per-strip loading.
ExplorePeptide Nasal Sprays
Metered intranasal delivery is the standard research route for neuropeptides and melanocortins because it exploits olfactory and trigeminal nerve transport pathways into the CNS.
ExploreImmune & Bioregulators
Thymic peptides and short bioregulator chains used in immune and longevity research.
High-Volume Ancillaries
Reconstitution supplies and solvents required by every lyophilized peptide protocol.
