Retatrutide in brief
Retatrutide comes in 10 strengths from 5mg to 100mg per vial, each a sealed box of ten, from $80.80 to $271.78 a box for the strengths sold singly. Per mg the spread is wide: RT60 (60mg x 10 vials) works out at $0.453 per mg against $0.808 per mg for RT10 (10mg x 10 vials), 44 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.
2 of the 10 strengths are on the shelf today (RT10 and RT20) and leave in 1 to 2 business days after payment clears. RT15, RT30, RT40 and RT60 are made to order, about four weeks. RT5, RT50, RT80 and RT100 are special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What Retatrutide is
Retatrutide is a synthetic 39-residue peptide of the glucagon peptide family, built on a GIP-type backbone. Three of its residues are not among the twenty coded amino acids: alpha-aminoisobutyric acid (Aib) at positions 2 and 20 and alpha-methyl-leucine at position 13. A C20 fatty diacid is attached through a gamma-glutamate and one short polyethylene-glycol spacer to the lysine at position 17, and the chain ends in an amide. Its price per milligram beside tirzepatide’s and semaglutide’s, strength by strength, is in Retatrutide vs Tirzepatide vs Semaglutide. Two other acylated chains of the glucagon family are set beside it: mazdutide, which carries a C20 diacid as retatrutide does, in Mazdutide vs Retatrutide, and survodutide, which carries a C18, in Retatrutide vs Survodutide.
The lipid tail is what dominates its behaviour in the laboratory: it makes the powder slow to wet, and it is part of the molecule’s mass, so identity is the mass with the lipid attached, 4,731.4, not the bare peptide’s. Its related substances of note are the des-lipid chain and a lipid positional isomer rather than an oxidised form, and the desk answers for them on a particular batch.
Registry and identity
- LY3437943 was the development code; retatrutide is the INN (WHO Proposed INN List 128) and the USAN name, and FDA's GSRS holds the compound as UNII NOP2Y096GV, CAS 2381089-83-2, with a sodium salt filed apart as UNII LQ42M82ZU6. FDA GSRS NOP2Y096GV, FDA GSRS LQ42M82ZU6
- GLP-3 RT is a trade nickname, absent from the FDA register's list of names for this compound; the line is released as retatrutide. FDA GSRS
- Set beside tirzepatide, its nearest neighbour on this list, the two 39-residue chains part company at nine positions: retatrutide hangs its lipid on lysine 17 through one AEEA spacer where tirzepatide uses lysine 20 and two, puts alpha-methyl-leucine at 13 where tirzepatide has Aib, and has Aib at 20. FDA GSRS NOP2Y096GV, FDA GSRS OYN3CCI6QE
- Tyrosine stands at 25 where tirzepatide has tryptophan, which leaves retatrutide with no tryptophan, methionine or cysteine at all; its deamidation sites are the glutamines at 3 and 19. FDA GSRS
- At high resolution its monoisotopic 4+ ion is at m/z 1183.125, from a monoisotopic mass of 4728.472 worked from C221H342N46O68. FDA GSRS, NIST
A listing in these registers identifies a substance; it is not an approval of this line.
Retatrutide beside Tirzepatide and Semaglutide
Retatrutide works out at $0.453 per mg at 60mg (RT60), its lowest by the single box. Its neighbours, on price alone: Tirzepatide at $0.305 per mg at 60mg (TR60), 4,813.5 g/mol, set side by side in Retatrutide vs Tirzepatide; Semaglutide at $0.301 per mg at 30mg (SM30), 4,113.6 g/mol, set side by side in Retatrutide vs Semaglutide.
Also set side by side: Retatrutide vs Tirzepatide vs Semaglutide, Retatrutide vs Survodutide and Mazdutide vs Retatrutide.
Reading a Retatrutide certificate of analysis (COA)
Identity by mass. Average mass 4731.4 (C221H342N46O68). In electrospray the protonated ions come near m/z 4732.4 (singly charged), m/z 2366.7 (doubly charged), m/z 1578.1 (3x charged), m/z 1183.9 (4x charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.
- Oxidation: no methionine, tryptophan or cysteine in the chain, so oxidised forms are not the impurity to expect.
- Deamidation: 2 glutamines. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
- Charge: near neutral pH about -4, acidic, counting the two free carboxyls of its lipid side chain.
- Identity is the mass of the whole lipidated chain, not of the peptide alone.
- Water content matters more than usual: the lipid keeps the cake from drying evenly, so a batch’s water result is worth asking the desk for when it matters to the work.

Questions about Retatrutide
Is GLP-3 RT, or GLP-3 Reta, the same as Retatrutide?
Yes. GLP-3 RT, GLP-3 Reta and Retatrutide are names for the same thing. GLP-3 RT and GLP-3 Reta are trade nicknames, not names on the FDA register; the line is released as retatrutide, development code LY3437943. The certificate and the vial label carry Retatrutide, which is the name the batch is released under.
What are Retatrutide’s formula, molecular weight and CAS number?
C221H342N46O68, molecular weight (average mass) 4,731.4 and monoisotopic mass 4,728.472, CAS 2381089-83-2 (FDA GSRS UNII NOP2Y096GV). The mass is the whole conjugate, the C20 fatty diacid and its spacer on lysine 17 included, not the bare chain.
How much does Retatrutide cost?
From $80.80 a sealed box of 10 vials, up to $271.78 for the largest strength sold singly, which works out at $0.453 per mg at its best-priced size. Special-order strengths, with a 50-box minimum, run from $62.80 to $418.64 a box. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. Every strength and its price per vial is in this page’s price table.
Which Retatrutide size is cheapest per mg?
Of the sizes sold by the single box, RT60, 60mg x 10 vials, at $0.453 per mg, which is 44 percent less per mg than RT10, at $0.808 per mg. Larger vials cost less per mg across the sizes sold by the single box, so match the vial to the size of the work first, then compare per mg. Sold only by special order, RT100 is lower still, at $0.419 per mg, with a 50-box minimum.
Can I buy a single vial of Retatrutide?
No. One sealed box of ten vials is the smallest quantity of a regular line; for Retatrutide that is RT10, 10mg x 10 vials, at $80.80. A first order must reach $100 of goods, so RT10 alone takes two boxes ($161.60) or one box beside other lines. RT5, RT50, RT80 and RT100 are special order and take a minimum of 50 boxes each. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Which Retatrutide strengths are in stock today?
RT10 at $80.80 a box, RT20 at $136.60 a box. RT15, RT30, RT40 and RT60 are made to order, about four weeks. RT5, RT50, RT80 and RT100 are special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is Retatrutide stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of Retatrutide?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. Retatrutide is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for Retatrutide?
Yes. For Retatrutide the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
