A stabilized analog of the full 44-amino-acid human growth hormone-releasing hormone (GHRH), FDA-approved to reduce excess visceral abdominal fat in people with HIV-associated lipodystrophy. It is also prescribed off-label for general fat loss and anti-aging purposes, a use with a much thinner evidence base than the approved indication.
Dose estudada 2 mg subcutaneous, once daily
A 29-amino-acid fragment of human growth hormone-releasing hormone (GHRH) that stimulates the pituitary to make and release its own growth hormone, rather than supplying GH directly. It was an FDA-approved drug for two decades under the brand name Geref; that product was discontinued for commercial reasons in 2008, and today's supply is almost entirely compounded.
Dose estudada 1–2 mcg/kg IV, single dose
A melanocortin-receptor agonist peptide. As the branded drug Vyleesi, a subcutaneous autoinjector, it is FDA-approved for acquired generalized hypoactive sexual desire disorder in premenopausal women. Sold separately online as unbranded "PT-141" — often as a nasal spray or vial, and often marketed to men — in a form and use that is not approved.
Dose estudada 1.75 mg subcutaneous, as needed
A naturally occurring copper-binding tripeptide present in human plasma that declines with age, sold as a cosmetic ingredient in skincare serums and creams under names like 'copper peptide.'
Dose estudada Topical, post-procedure skincare regimen
NOTA D·Insuficiente ou inseguro A synthetic 15-amino-acid peptide derived from a fragment of a human gastric protein, sold online for injury recovery and gut healing.
Dose estudada None exists
NOTA D·Insuficiente ou inseguro A synthetic analog of growth hormone-releasing hormone (GHRH), engineered to resist the rapid breakdown that limits natural GHRH and sermorelin. It is not an FDA-approved drug and is sold online as a research chemical, not for human use. Two distinct products share this name and must not be confused with each other: a long-acting version bound to a Drug Affinity Complex (DAC), and a short-acting version without it.
Dose estudada 30–90 mcg/kg subcutaneous
NOTA D·Insuficiente ou inseguro A synthetic five-amino-acid peptide that activates the ghrelin receptor to trigger growth hormone release, often sold combined with CJC-1295 as a 'GH-boosting stack.' It is not an FDA-approved drug and is sold as a research chemical, not for human use.
Dose estudada IV infusion, ~4–140 nmol/kg
NOTA D·Insuficiente ou inseguro A synthetic version of a naturally occurring 43-amino-acid protein, sold online as an injectable "research chemical" marketed for tendon, ligament and muscle injury recovery, often alongside BPC-157.
Dose estudada 0.01%–0.03% topical gel
NOTA D·Insuficiente ou inseguro A synthetic analogue of alpha-melanocyte-stimulating hormone, injected to darken skin without sun exposure. Sold online and through gray-market tanning and wellness sources for tanning and, off-label, for libido and erectile function.
Dose estudada None exists
NOTA D·Insuficiente ou inseguro A modified fragment of the C-terminal end of human growth hormone, engineered to isolate growth hormone's fat-metabolising effect without its growth-promoting or blood-sugar effects. Sold online as an injectable peptide marketed for fat loss.
Dose estudada Oral, approximately 0.25–1 mg/day
