Neither of these is a peptide and neither has an exact mass, which is the first thing to settle before reading either certificate the way you would read a peptide’s. ACE-031 is a recombinant fusion glycoprotein: the extracellular domain of activin receptor type IIB joined to a human IgG1 Fc and assembled as a disulfide-linked homodimer of roughly 100 kDa. Follistatin is a secreted, cysteine-rich, N-glycosylated activin-binding glycoprotein, the long isoform arising from a 344-residue precursor. Glycosylation is heterogeneous by nature, so neither line has a single molecular weight to quote and both are identified and assayed on the batch certificate rather than against a figure on a sheet. ACE-031 is recombinant and its certificate carries an endotoxin line accordingly. On this list both are single 1 mg lines, so the comparison below is box price against box price rather than a per-milligram spread.

Questions
Which is cheaper per mg, ACE-031 or Follistatin?
ACE-031, at $1.66 per mg for its best-priced strength (AE1) against $18.39 per mg for Follistatin (FN1), 91 percent less. Compare at the vial size you will actually use; the gap changes with strength.
Which comes in more strengths, ACE-031 or Follistatin?
Both are offered in one strength. Every strength is a separate line with its own code, price and stock state.
Can ACE-031 and Follistatin go in one order?
Yes. Any lines can share an order; the minimum is $300 of goods per order, or $100 on a first order, and one sealed box of ten per line. Lines on the shelf ship in 1 to 2 business days; made-to-order lines follow in about two weeks, at no extra freight.
Are ACE-031 and Follistatin tested to the same specification?
Yes: purity not less than 98.0 percent by RP-HPLC, identity by mass, water content, net content within 5 percent of label, and a retest date, with a certificate of analysis per batch. What differs is what each certificate has to look for, which is set by the molecule and described on each compound’s own page.
