Xeno Labs Tamox – 20mg/50tabs

Recommended Dosage for PCT:
20-40mg daily for 4-6 weeks. Most guys use 40mg daily (two tablets) for weeks 1-2, then 20mg daily (one tablet) for weeks 3-4. Some extend to 6 weeks for longer or harsher cycles.

For Gyno Treatment:
40-60mg daily until lumps shrink, then taper down to 20mg daily for maintenance. Can take 3-6 months to see full gyno reversal.

For Gyno Prevention On-Cycle:
10-20mg daily while running aromatizing compounds. This is less common now since AIs work better for prevention.

When to Start PCT:
The timing depends on what steroids you used:

• Short esters (Test Prop, NPP): Start PCT 3-4 days after last injection
• Medium esters (Test E, Test Cyp): Start PCT 2 weeks after last injection
• Long esters (Deca, Test U): Start PCT 3-4 weeks after last injection

Standard PCT Protocol:
Week 1-2: 40mg Tamoxifen daily + 50mg Clomid daily
Week 3-4: 20mg Tamoxifen daily + 25mg Clomid daily
Week 5-6 (optional): 20mg Tamoxifen daily

How to Take:
Take with or without food. Swallow tablets whole with water. Take at the same time each day to maintain stable blood levels.

Missing Doses:
If you miss a dose, take it as soon as you remember. If it's almost time for your next dose, skip the missed one. Don't double up.

Most Common:

• Hot flashes (feeling warm and sweaty)
• Nausea or upset stomach
• Mood swings or feeling emotional
• Headaches
• Fatigue or low energy
• Reduced libido temporarily during PCT

Less Common:

• Vision problems (blurry vision, eye floaters)
• Blood clots (rare but serious)
• Stroke risk (very rare)
• Liver toxicity with long-term use
• Weight gain from water retention
• Joint pain

Important Warnings:
Stop immediately if you develop severe leg pain, chest pain, trouble breathing, or sudden vision changes. These could signal blood clots - get medical help right away.

During PCT:
Some guys feel terrible during PCT regardless of Tamoxifen - this is normal as your hormones rebalance. Low energy, mood swings, and reduced libido are expected. These improve as your natural testosterone comes back.

Active Ingredient:
Tamoxifen Citrate (30.4mg citrate salt equivalent to 20mg tamoxifen base)

Dosage Strength:
20 mg per tablet (as tamoxifen base)

Quantity:
Typically 30-60 tablets per package

Intended Use:
Primary FDA-approved uses: Treating breast cancer in men and women, reducing breast cancer risk in high-risk women, treating DCIS after surgery/radiation.
Primary bodybuilding use: Post Cycle Therapy (PCT), gynecomastia treatment and prevention, restoring natural testosterone production, maintaining gains after cycles.

Classification:
SERM (Selective Estrogen Receptor Modulator) - Non-steroidal antiestrogen

Mechanism of Action:
Competitively binds to estrogen receptors in various tissues. Acts as estrogen antagonist in breast tissue (blocks estrogen), but as estrogen agonist in hypothalamus/pituitary (stimulates LH/FSH production). This dual action makes it ideal for PCT.

Half-Life:
5-7 days for tamoxifen
14 days for active metabolite (N-desmethyl tamoxifen)

Time to Peak Plasma Concentration:
5 hours after single dose

Time to Steady State:
Approximately 4 weeks for tamoxifen, 8 weeks for N-desmethyl metabolite

Bioavailability:
Well absorbed orally (specific percentage varies individually)

Active Metabolites:
N-desmethyl tamoxifen (primary active metabolite with similar potency)
4-hydroxytamoxifen (minor metabolite but most potent)

Protein Binding:
Very high (>99%)

Metabolism:
Hepatic via CYP3A4, CYP2D6, and other enzymes

Excretion:
Primarily feces (65%), urine (9%) over several weeks

Effects on Hormone Levels:

• Increases LH by 150%
• Increases FSH by 200%
• Increases testosterone by 42-83% (dose dependent)
• Blocks estrogen receptor binding in breast tissue

Molecular Formula:
C26H29NO (tamoxifen base)

Molecular Weight:
371.51 g/mol

Chemical Name:
