SLU-PP-332 at a glance

SLU-PP-332 is not a peptide at all. It is a small synthetic organic compound with the formula C18H14N2O2 and a molecular weight of 290.3 g/mol, created at Saint Louis University as a tool for activating the estrogen-related receptors (ERRs). Despite the name, ERRs do not respond to estrogen, and the compound does not act on classical estrogen receptors. On this marketplace it is listed in capsule form, stated at 1 mg per capsule.

Price and availability

A kit of 100 vials at 250mcg each (25 mg in total) from TFC Peptides, shipped from Tianjin, China. $18.00 buys the whole kit, which is $0.72/mg. 3 brands sell SLU-PP-332 on GLP1 Forum Escrow, with a typical price of $0.034–$2.33 per mg (median $0.23); this listing is inside that range. Your payment waits in escrow until you confirm the parcel arrived, and only then is it released to the brand.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Request the batch COA · How group testing works

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

The three ERR subtypes, alpha, beta and gamma, are orphan nuclear receptors that work with the coactivator PGC-1alpha to switch on genes for mitochondrial biogenesis, fatty-acid oxidation and oxidative muscle fibers. SLU-PP-332 is reported to activate all three, with its strongest activity at ERR-alpha in the original characterization. In mouse skeletal muscle, treatment has been associated with a shift toward oxidative fiber types and with gene-expression changes resembling those after endurance training, which is the basis for the exercise-mimetic label. Selectivity and off-target effects are still being characterized.

Research and regulatory status

Published studies are preclinical, mostly from the group that designed the compound, and use mice to examine obesity, insulin resistance, endurance capacity and age-related decline. In those papers it functions as an academic chemical probe rather than a drug candidate. No human trials have been reported, no regulator has approved it, and nothing is known about its effects or pharmacokinetics in people. Online interest in the compound has run well ahead of the evidence.

Checking the lab data

For a capsule product, the report should confirm identity by LC-MS showing the expected mass for C18H14N2O2, around 290 g/mol, and give HPLC purity for the active compound. Just as important is an assay of the amount per capsule against the 1 mg label, since small-molecule fills at that scale can vary. A note on excipients, and ideally screening for residual solvents or heavy metals, rounds out a credible certificate.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Buyer questions

Why is SLU-PP-332 called an exercise mimetic?

The label comes from mouse studies in which the compound produced muscle gene-expression changes and fiber-type shifts similar to those seen after endurance training. It describes a pattern observed in animal tissue, not an established effect in people, and a molecular signature that resembles exercise is very different from the full physiology of exercise.

Why is it sold as capsules rather than vials?

As a small organic molecule, SLU-PP-332 does not need the freeze-dried vial format used for most peptides, and brands on the marketplace offer it as filled capsules. That format shifts the key quality question to fill accuracy and excipient content, so a report that assays the amount per capsule is more informative than purity alone.

How much SLU-PP-332 is in this listing?

100 vials of 250mcg each — 25 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does TFC Peptides get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
