Evidence

Weight

3 ingredients

Weight

Semaglutide

Tier 1 · FDA-approved / strong evidence

The medication behind the biggest shift in weight care in decades. A weekly injection that quiets appetite, so you feel full sooner and think about food less. Same molecule as Ozempic and Wegovy.

Weight

Tirzepatide

Tier 1 · FDA-approved / strong evidence

A weekly injection that works on two appetite hormones instead of one, producing some of the largest weight-loss results ever seen from a medication. The molecule sold as Mounjaro and Zepbound.

Weight

Retatrutide

Tier 3 · Early evidence — investigational

The next-generation weight medication everyone in the field is watching — it works on three hormone pathways at once. Early trials look striking, but it isn't FDA-approved yet, which is why we keep it to a waitlist.

Recover & Glow

5 ingredients

Recover & Glow

BPC-157

Tier 3 · Early evidence — investigational

A peptide popular in recovery and gut-health circles, used hoping to speed healing of tendons, muscle, and the gut lining. Straight talk: most of the evidence is from animal studies, not humans.

Recover & Glow

TB-500 (Thymosin Beta-4 fragment)

Tier 4 · Experimental — limited human data

A peptide used in recovery stacks, often alongside BPC-157, aiming to support tissue repair and flexibility. Like BPC-157, its evidence is mainly from animal research.

Recover & Glow

GHK-Cu (Copper peptide)

Tier 3 · Early evidence — investigational

A copper-carrying peptide best known in skincare, studied for firmer, healthier-looking skin and wound healing. A favorite in glow routines.

Recover & Glow

Glutathione

Tier 2 · Approved use / good evidence

Your body's master antioxidant — a molecule every cell makes to neutralize damage. Used for general wellness, recovery, and skin brightening.

Recover & Glow

KPV

Tier 4 · Experimental — limited human data

A small peptide studied for calming inflammation, particularly in the gut. The interest is real but the human evidence is still early.

Energy & Longevity

8 ingredients

Energy & Longevity

NAD+

Tier 3 · Early evidence — investigational

A molecule every cell uses to turn food into energy. Levels fall with age, and people supplement it (injection, IV, or nasal spray) hoping to support energy, recovery, and healthy aging.

Energy & Longevity

Sermorelin

Tier 2 · Approved use / good evidence

Nudges your body to make more of its own growth hormone rather than replacing it. Used for sleep quality, recovery, and body composition.

Energy & Longevity

CJC-1295 & Ipamorelin

Tier 3 · Early evidence — investigational

Growth-hormone-support peptides often combined in one stack — one extends the signal, the other triggers release — used for recovery, sleep, and body composition.

Energy & Longevity

Tesamorelin

Tier 2 · Approved use / good evidence

A growth-hormone-releasing peptide that's actually FDA-approved — specifically to reduce excess abdominal fat in people with HIV-associated lipodystrophy. Broader longevity use is off-label.

Energy & Longevity

MOTS-c

Tier 4 · Experimental — limited human data

A 'mitochondrial peptide' studied for metabolism and exercise capacity. Genuinely interesting science, but early-stage and experimental.

Energy & Longevity

SS-31 (Elamipretide)

Tier 4 · Experimental — limited human data

A peptide that targets the mitochondria directly, studied for energy and age-related conditions. It's in human trials but not approved.

Energy & Longevity

Epithalon

Tier 4 · Experimental — limited human data

A peptide promoted in longevity circles for claimed effects on the aging 'clock.' Honest read: human evidence is very thin.

Used in these stacks

Energy & Longevity

Semax & Selank

Tier 4 · Experimental — limited human data

'Nootropic' peptides developed in Russia, used for focus, stress, and mood. Some human use history there, but limited rigorous Western trial data.

Intimacy

3 ingredients

Intimacy

Tadalafil & Sildenafil

Tier 1 · FDA-approved / strong evidence

The well-known, FDA-approved medications for erectile function (Cialis and Viagra). Tadalafil lasts longer; sildenafil acts a bit faster. Backed by decades of data.

Intimacy

PT-141 (Bremelanotide)

Tier 2 · Approved use / good evidence

Works on desire in the brain rather than blood flow in the body — a different mechanism from the '-afil' drugs. FDA-approved (as Vyleesi) for low sexual desire in premenopausal women; used off-label more broadly.

Intimacy

Oxytocin

Tier 2 · Approved use / good evidence

The natural 'bonding' hormone. In compounded intimacy products it's used aiming to enhance connection and arousal.

Hair

2 ingredients

Hair

Finasteride

Tier 1 · FDA-approved / strong evidence

The other pillar of proven hair care, included in our 'His' spray. It targets the hormone behind male-pattern hair loss.

Hormones

6 ingredients

Hormones

Testosterone

Tier 1 · FDA-approved / strong evidence

A well-established treatment for men with genuinely low levels, supporting energy, mood, libido, and muscle. A medical therapy, not a shortcut — which is why it's carefully monitored.

Used in these stacks

Hormones

Enclomiphene

Tier 2 · Approved use / good evidence

Raises testosterone by encouraging your body to make more of its own — an alternative to replacement that can preserve fertility. Popular with younger men.

Used in these stacks

Hormones

Gonadorelin

Tier 2 · Approved use / good evidence

Often added to a testosterone plan to help keep the body's own hormone signaling — and fertility — switched on.

Used in these stacks

Hormones

Anastrozole

Tier 1 · FDA-approved / strong evidence

Sometimes added in small doses to a testosterone plan to keep estrogen in balance. An approved medication used carefully and sparingly here.

Used in these stacks

Hormones

Estrogen, Progesterone & DHEA (balance for her)

Tier 2 · Approved use / good evidence

For perimenopause and menopause, estrogen and progesterone (sometimes with DHEA) can ease symptoms and support wellbeing. Real hormone therapies, tailored by a provider.
