ACE-031 1mg — Research Peptide Canada
ACE-031 is a soluble decoy receptor built by fusing the extracellular domain of activin receptor type IIB to an IgG1 Fc region. It sequesters myostatin and related TGF-beta ligands before they reach the membrane receptor.

About ACE-031 1mg
Rather than blocking myostatin at the receptor, ACE-031 removes it from circulation: the ActRIIB extracellular domain binds myostatin, activin A and GDF-11 with high affinity, and the Fc fusion gives the construct a long half-life. That broad ligand promiscuity is both its strength as a research tool and the reason its clinical development in Duchenne muscular dystrophy was halted, since off-target ligand sequestration produced vascular effects. It is a large recombinant fusion protein, not a peptide, and requires strict cold-chain handling and gentle reconstitution to avoid denaturation.
Storing and handling ACE-031 1mg
Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.
Shipping ACE-031 1mg within Canada
Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, arriving in two to five business days with a tracking number on every one. Orders over CA$200 ship free; see the shipping page for the dispatch cut-off and transit window.
ACE-031 1mg questions
Are research peptides like ACE-031 1mg legal in Canada?
ACE-031 1mg is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.
Is ACE-031 1mg shipped from within Canada?
Yes. Every ACE-031 1mg order leaves British Columbia, Canada and travels entirely within the country. Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.
Does ACE-031 1mg come with a certificate of analysis?
Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every ACE-031 1mg lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.
How is ACE-031 1mg supplied and stored?
As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.
What fill is ACE-031 1mg supplied in?
ACE-031 1mg is supplied in a single 1mg fill, released against a >99% specification.
