Every compound we stock —plus the ones we don’t.

Filter by mechanism or by how much human evidence sits behind a compound. Reference profiles are included for compounds we have no intention of selling, because knowing what something is matters more than whether we happen to stock it.

Cartalax 20 mg

Longevity & Mitochondrial

Sold for cartilage. One study has ever put it in contact with cartilage — in a dish, where the crude extract beat it. No human exposure on record.

Cerebrolysin 60 mg

Cognitive & Sleep

Peptide preparation used clinically in Europe and Asia for stroke and dementia.

Preclinical only

CJC-1295 (No DAC) 10 mg

Growth Hormone Axis

Modified GRF(1-29). Every published CJC-1295 trial used the with-DAC conjugate, a different molecule; this form has no human data.

DSIP 10 mg

Cognitive & Sleep

Nonapeptide isolated from rabbit cerebral venous blood. Genuinely tested in controlled human sleep trials — and the best-designed one found no meaningful benefit.

Human trial data

Eloralintide 5 mg

Metabolic & Weight

Not cagrilintide, and not a GLP-1. A 263-person phase 2 lost 9% at the low end of its range and 20% at the top — and at the low end nausea came in below placebo.

Epitalon 10 mg

Pineal tetrapeptide credited with the famous Russian mortality trials — which used a different substance.

GHRP-2 10 mg

Growth Hormone Axis

Approved in Japan as a one-hour diagnostic test at 100 µg. A 10 mg vial holds a hundred of those doses. On FDA's Category 2 list.

Limited human data

GHRP-6 10 mg

Growth Hormone Axis

The compound the class was built from, and the one FDA singled out. Five human studies, the longest 34 hours — and not one measured appetite.

GLOW 70 mg

Blends & Stacks

Three-component recovery and dermal blend; the components have very different evidence bases.

Glutathione 600 mg

The cell's principal redox buffer — and the one compound here where injecting it is the worst-evidenced way to take it.

Gonadorelin 2 mg

Hormonal & Other

Strong evidence — all of it from a pump that pulses every 90 minutes. The way it is sold has never been studied.

Hexarelin 5 mg

Growth Hormone Axis

The only one in this class with human cardiac data in patients — and the effect fades as the heart gets sicker. A discontinued drug candidate.

Long-arginine-3 IGF-1 with reduced binding-protein affinity and extended half-life.

Ipamorelin 10 mg

Mazdutide 10 mg

Oxytocin 10 mg

Cognitive & Sleep

Licensed since 1981 for labour induction, dosed in nanograms per minute. The social literature failed its replications, and the largest autism trial moved the primary outcome by 0.2 points.

Pinealon 10 mg

Longevity & Mitochondrial

The name says pineal. Zero papers link it to melatonin or sleep, and the one pineal-tissue experiment found it inactive. The neuron work is real.
