Testosterone Cypionate
INJECTION
Overview: Testosterone Cypionate is a long-acting ester of testosterone and one of the most widely prescribed forms of testosterone replacement therapy (TRT) for men with hypogonadism (low testosterone). The cypionate ester provides a sustained release profile lasting 7–14 days per injection.
How It Works
- Exogenous testosterone directly raises serum testosterone levels
- Binds androgen receptors throughout the body to exert androgenic and anabolic effects
- Promotes nitrogen retention and protein synthesis in muscle tissue
- Stimulates red blood cell production via EPO stimulation in the kidneys
- Cypionate ester is cleaved by esterases, releasing free testosterone gradually over 7–14 days
Key Benefits
- Restores testosterone to physiological levels in hypogonadal men
- Increased muscle mass, strength, and body composition
- Improved energy, libido, and mood
- Bone density preservation and improvement
- Cognitive function and wellbeing enhancement
- Convenient weekly or biweekly injection schedule
Testosterone Cypionate w/ Zinc
INJECTION
Overview: Testosterone Cypionate compounded with zinc combines standard TRT with zinc supplementation in a single injection. Zinc is an essential cofactor in testosterone synthesis and plays a key role in aromatase inhibition — helping to maintain the testosterone-to-estrogen ratio without the need for separate aromatase inhibitor medications.
How It Works
- All mechanisms of standard Testosterone Cypionate (see above)
- Zinc: Essential cofactor for 5-alpha reductase and aromatase enzyme activity
- Zinc inhibits aromatase — reduces conversion of testosterone to estradiol
- Zinc supports natural LH and FSH pulsatility even under TRT
- Zinc is required for testosterone receptor binding and nuclear translocation
Key Benefits
- All benefits of standard TRT
- Reduced estrogen conversion — may decrease need for separate aromatase inhibitor
- Convenience — single injection delivers both TRT and zinc support
- Improved testosterone-to-estrogen ratio management
- Zinc’s additional benefits: immune support, wound healing, prostate health
Testosterone Enanthate
INJECTION
Overview: Testosterone Enanthate is another long-acting testosterone ester with a slightly shorter release profile than Cypionate (5–10 days). It is one of the two most commonly prescribed TRT formulations and is functionally very similar to Testosterone Cypionate with minor pharmacokinetic differences.
How It Works
- Identical mechanism to Testosterone Cypionate — binds androgen receptors systemically
- Enanthate ester has a carbon chain one unit shorter than cypionate
- Half-life approximately 4.5 days vs. 5 days for cypionate — minor clinical difference
- Release curve slightly faster peak and decline vs. cypionate
Key Benefits
- Identical clinical benefits to Testosterone Cypionate
- Slightly more frequent peak — some patients prefer for libido and energy stability
- Well-established formulation with decades of clinical data
- Interchangeable with Cypionate for most clinical purposes
Testosterone Cream
CREAM
Overview: Testosterone cream provides transdermal testosterone delivery through the skin, bypassing first-pass liver metabolism. It is used in both men (TRT) and women (for low testosterone symptoms) and offers a needle-free alternative with flexible dosing. Applied daily, it maintains relatively stable testosterone levels without the peaks and troughs associated with longer-acting injections.
How It Works
- Testosterone absorbs through the skin into dermal capillaries and systemic circulation
- Bypasses hepatic first-pass metabolism — liver not exposed to high testosterone concentrations
- Daily application produces more stable serum levels vs. weekly injections
- Skin’s 5-alpha reductase converts some testosterone to DHT locally
Key Benefits
- Needle-free testosterone delivery — ideal for injection-averse patients
- Stable daily hormone levels — avoids peaks/troughs of injectable TRT
- Used in women for low libido, energy, and mood at much lower doses
- Flexible dosing — easy to titrate up or down
- Application site can be varied (shoulder, inner arm, thigh, scrotum for higher absorption)
Progesterone Capsule
CAPSULE
Overview: Oral micronized progesterone (Prometrium) is bioidentical progesterone — identical in molecular structure to endogenous progesterone — in a micronized form that improves absorption. Used primarily in women for hormone replacement therapy, menstrual irregularities, and perimenopause/menopause management.
How It Works
- Binds progesterone receptors throughout the body — uterus, brain, breast, cardiovascular tissue
- Provides endometrial protection when used with estrogen therapy
- Sedative effect via GABA-A receptor positive allosteric modulation (metabolite allopregnanolone)
- Anti-estrogenic effect in the uterus — prevents estrogen-driven endometrial proliferation
Key Benefits
- Endometrial protection in women on estrogen therapy — reduces endometrial cancer risk
- Improved sleep quality — allopregnanolone metabolite has sedative, anxiolytic effects
- Mood stabilization and anxiety reduction
- Supports menstrual cycle regularity
- Bioidentical — matches body’s natural progesterone structure exactly
- Potentially protective for breast tissue vs. synthetic progestins
Progesterone Cream
CREAM
Overview: Transdermal progesterone cream provides topical delivery of bioidentical progesterone through the skin. It is used for perimenopause, PMS, cycle regulation, and as part of hormone balancing protocols. Cream delivery avoids the sedative first-pass liver metabolism of oral progesterone.
How It Works
- Transdermal absorption directly into systemic circulation
- Avoids significant hepatic first-pass metabolism — different metabolite profile vs. oral
- Less allopregnanolone production (sedative metabolite) than oral route
- Direct tissue delivery of bioidentical progesterone to receptor sites
Key Benefits
- Non-sedating progesterone delivery — preferred for daytime use
- PMS and perimenopausal symptom relief
- Hormone balance support in estrogen-dominant conditions
- Convenient topical application without injection
- Bioidentical — identical to endogenous progesterone
Progesterone Troche
TROCHE
Overview: Progesterone troches are sublingual/buccal lozenges that dissolve in the mouth, allowing progesterone to absorb through the oral mucosa directly into the bloodstream. This route combines the rapid absorption of mucosal delivery with a metabolite profile between oral and topical administration.
How It Works
- Sublingual/buccal absorption through highly vascular oral mucosa
- Partially bypasses hepatic first-pass metabolism
- Intermediate allopregnanolone production — milder sedation vs. oral capsule
- Direct systemic delivery with rapid onset
Key Benefits
- Faster absorption than topical cream
- Intermediate sedation — less than oral, suitable for some daytime use
- Convenient — no injection, dissolves quickly
- Good option for patients who dislike creams or capsules
Progesterone
INJECTION
Overview: Injectable progesterone in oil provides reliable, high-bioavailability progesterone delivery via intramuscular injection. This route is used when consistent, precise progesterone levels are required — particularly in fertility treatments, early pregnancy support, and cases where other routes have been insufficient.
How It Works
- IM injection into gluteal muscle — absorbed from oil depot into systemic circulation
- Bypasses GI tract entirely — 100% bioavailability vs. partial oral absorption
- Steady release from oil depot over 24–48 hours
- Direct systemic delivery ensures reliable, measurable serum progesterone levels
Key Benefits
- Highest bioavailability of all progesterone routes
- Reliable and precise dosing — particularly important for fertility and early pregnancy
- Used in IVF protocols as the gold standard for luteal phase support
- Consistent serum levels with predictable pharmacokinetics
Estradiol Capsule
CAPSULE
Overview: Oral bioidentical estradiol in capsule form provides systemic estrogen replacement for women experiencing menopause, surgical menopause, or estrogen deficiency. Estradiol is the most potent and physiologically active form of estrogen, and bioidentical preparations match the body’s natural estrogen exactly.
How It Works
- Absorbed through the GI tract and undergoes first-pass hepatic metabolism
- Binds estrogen receptors (ERalpha and ERbeta) throughout the body
- Stimulates hepatic protein synthesis — including clotting factors and sex hormone binding globulin (SHBG)
- Regulates over 400 physiological functions including bone, cardiovascular, neurological, and reproductive systems
Key Benefits
- Relief of menopausal symptoms — hot flashes, night sweats, vaginal atrophy
- Bone density preservation — reduces osteoporosis risk
- Cardiovascular protection when initiated in early menopause (timing hypothesis)
- Cognitive protection and mood stabilization
- Improved skin quality and collagen maintenance
Estradiol Cypionate
INJECTION
Overview: Estradiol Cypionate is a long-acting injectable ester of estradiol providing sustained estrogen release over 1–4 weeks per injection. Used in gender-affirming hormone therapy and menopausal HRT when consistent, high-bioavailability estrogen delivery is preferred.
How It Works
- Cypionate ester slowly cleaved after IM injection, releasing free estradiol over 1–4 weeks
- Bypasses hepatic first-pass metabolism — different risk profile vs. oral estrogen
- Directly binds systemic estrogen receptors without liver SHBG stimulation
Key Benefits
- Sustained, stable estrogen levels with infrequent dosing
- Bypasses liver — reduced SHBG elevation and potentially lower clotting factor stimulation vs. oral
- High bioavailability — reliable serum estradiol levels
- Infrequent dosing (every 1–4 weeks) improves compliance
Estradiol Valerate w/ DHEA
INJECTION
Overview: A combination injectable formulation providing both Estradiol Valerate (long-acting estrogen ester) and DHEA (Dehydroepiandrosterone) — the body’s most abundant steroid hormone and a precursor to both estrogen and testosterone. This combination addresses multiple hormonal needs simultaneously.
How It Works
- Estradiol Valerate: Cleaved to release free estradiol over 1–2 weeks after IM injection
- DHEA: Precursor hormone converted peripherally to estrogens and androgens in target tissues
- DHEA: Binds its own DHEA-specific receptors with independent effects on immune function and wellbeing
- Combination provides both direct estrogen and androgen precursor support in a single injection
Key Benefits
- Estrogen replacement with concurrent androgen precursor support
- DHEA improves energy, libido, mood, and wellbeing beyond estrogen alone
- DHEA supports adrenal function and stress resilience
- Single injection provides comprehensive hormonal support
- DHEA levels decline sharply with age — combination addresses multiple deficiencies
Bi-Est 1mg 80:20 Estriol/Estradiol Cream
CREAM
Overview: Bi-Est is a compounded bioidentical estrogen cream combining two natural estrogens: estriol (the weaker, protective estrogen) and estradiol (the potent primary estrogen) in an 80:20 ratio. This formulation mimics the body’s natural estrogen balance and is widely used in bioidentical hormone replacement therapy (BHRT).
How It Works
- Estriol (80%): Weaker estrogen — binds ERbeta preferentially, may have protective effects in breast tissue
- Estradiol (20%): Potent estrogen — provides the primary therapeutic estrogenic effects
- Transdermal absorption bypasses hepatic first-pass — lower SHBG and clotting factor stimulation
- 80:20 ratio designed to balance potency with estriol’s potentially protective properties
Key Benefits
- Relief of menopausal symptoms with bioidentical hormones
- Estriol component may provide breast tissue protection vs. estradiol alone
- Transdermal delivery — improved safety profile vs. oral estrogen for clotting risk
- Vaginal health support — estriol particularly beneficial for vaginal atrophy
- Mimics the natural estrogen ratio found in premenopausal women
hCG (Pregnyl)
INJECTION
Overview: Human Chorionic Gonadotropin (hCG) is a hormone that mimics LH (Luteinizing Hormone) at the LH receptor. In men on TRT, it is used to maintain testicular function, size, and fertility. In fertility medicine, it is used to trigger ovulation. hCG Pregnyl is the brand name for pharmaceutical-grade hCG derived from the urine of pregnant women.
How It Works
- Binds and activates LH/hCG receptors on Leydig cells in the testes
- Stimulates intratesticular testosterone production — maintaining fertility on TRT
- Prevents testicular atrophy associated with exogenous testosterone suppressing LH
- In women: triggers final follicular maturation and ovulation by mimicking the LH surge
- Maintains Sertoli cell function and sperm production (spermatogenesis)
Key Benefits
- Prevents testicular atrophy during TRT
- Preserves male fertility during testosterone therapy
- Maintains intratesticular testosterone (important for spermatogenesis)
- Trigger for ovulation in fertility treatments (IUI, IVF)
- Supports natural testicular function and hormone production
Enclomiphene Capsule
CAPSULE
Overview: Enclomiphene is the trans-isomer of clomiphene citrate — a selective estrogen receptor modulator (SERM) that blocks estrogen receptors in the hypothalamus and pituitary, causing the brain to increase production of LH and FSH, which in turn stimulates natural testosterone production. Unlike TRT, Enclomiphene raises testosterone while preserving fertility.
How It Works
- Competitively blocks estrogen receptors in the hypothalamus and pituitary
- Removes estrogen’s negative feedback on GnRH, LH, and FSH release
- Elevated LH stimulates Leydig cells to produce more testosterone
- Elevated FSH supports spermatogenesis — fertility preserved or improved
- Enclomiphene (trans-isomer) isolated from Clomiphene — removes the estrogenic cis-isomer (zuclomiphene)
Key Benefits
- Raises testosterone naturally — preserves the HPG axis unlike exogenous TRT
- Maintains or improves fertility — unlike TRT which suppresses sperm production
- Oral capsule — no injection required
- Normalizes LH and FSH alongside testosterone
- Ideal for younger men who want testosterone optimization without fertility impact
- Post-TRT recovery — restores natural production after a TRT cycle
Anastrozole Capsule
CAPSULE
Overview: Anastrozole is a third-generation aromatase inhibitor (AI) that blocks the enzyme aromatase, which converts testosterone and other androgens into estrogens. Used on TRT to manage elevated estradiol (E2) levels that can cause side effects including gynecomastia, water retention, mood changes, and reduced libido.
How It Works
- Competitively and selectively inhibits aromatase (CYP19A1) enzyme
- Aromatase converts testosterone to estradiol in peripheral tissues (fat, liver, muscle)
- By blocking conversion, Anastrozole raises testosterone:estradiol ratio
- Does not affect cortisol, aldosterone, or other adrenal steroid synthesis
Key Benefits
- Reduces elevated estradiol in men on TRT
- Prevents and treats gynecomastia
- Reduces water retention associated with high estrogen
- Improves libido and mood when high E2 is contributing to symptoms
- Allows higher testosterone doses without proportional estrogen increase
DHEA Capsules
CAPSULE
Overview: DHEA (Dehydroepiandrosterone) is the most abundant circulating steroid hormone in the human body and serves as a precursor to both androgens and estrogens. Peak levels occur in the mid-20s and decline by up to 80% by age 70 — a decline closely associated with aging. Supplementation aims to restore youthful DHEA levels.
How It Works
- Converted peripherally in tissues to testosterone, estradiol, and other androgens/estrogens
- Binds its own specific DHEA receptors independent of sex steroid conversion
- Modulates immune function — anti-inflammatory and immunomodulatory effects
- Supports adrenal function and cortisol stress response
- Neuroprotective — DHEA receptors present in brain tissue
Key Benefits
- Restores testosterone and estrogen precursor availability as endogenous DHEA declines
- Improved energy, mood, and sense of wellbeing
- Enhanced libido and sexual function
- Immune system support and anti-inflammatory activity
- Bone density support
- Anti-aging effects — correlates with longevity markers in population studies
Oxandrolone Capsule
CAPSULE
Overview: Oxandrolone (brand name: Anavar) is a synthetic anabolic-androgenic steroid with a very favorable anabolic-to-androgenic ratio. It is FDA-approved for weight gain after surgery, infection, or trauma, and for offsetting protein catabolism from prolonged corticosteroid use. In clinical practice it is also used for lean muscle preservation, fat loss, and anti-aging in appropriate patients.
How It Works
- Binds androgen receptors with high affinity and specificity
- Strong anabolic effect on protein synthesis and nitrogen retention in muscle
- Relatively low androgenic potency — reduced conversion to DHT vs. testosterone
- Does not aromatize to estrogen — no water retention or gynecomastia risk
- Promotes fat oxidation, particularly visceral fat
Key Benefits
- Significant lean muscle preservation and gain with minimal androgenic side effects
- Fat loss — particularly visceral adipose tissue
- Strength increase disproportionate to weight gain
- Well tolerated in women at low doses (rare for anabolic steroids)
- Used in burn recovery, muscle-wasting disease, and cachexia
- Does not aromatize — no estrogen-related side effects
Oxandrolone Troche
TROCHE
Overview: Oxandrolone in sublingual troche form allows the compound to absorb through oral mucosa, partially bypassing first-pass hepatic metabolism. This may reduce liver enzyme elevation compared to swallowed oral tablets while maintaining anabolic efficacy.
How It Works
- Sublingual absorption through oral mucosa into systemic circulation
- Reduces hepatic first-pass metabolism compared to swallowed oral form
- Same androgen receptor binding mechanism as oral Oxandrolone
- Potentially improved liver safety profile due to reduced portal vein delivery
Key Benefits
- All benefits of oral Oxandrolone
- Potentially reduced hepatotoxicity vs. swallowed oral form
- Convenient sublingual administration
