GP Oxan Review: Geneza Pharmaceuticals Anavar Tested
GP Oxan review: Geneza Anavar lab-tested above its 10 mg label, GP Oxan vs GP Anavar 50, clinical data on fat loss and HDL, fakes and side effects.
What GP Oxan Is
GP Oxan is Geneza Pharmaceuticals' Anavar, oxandrolone labelled at 10 mg per tablet and usually sold in a 50-tablet pouch. It is the brand's most popular oral and also its best-documented one: a community-funded analysis at SIMEC AG, the Swiss lab AnabolicLab uses, found GP Oxan slightly above its labelled 10 mg. For an underground oral that is a strong result, because oxandrolone is expensive to source and is the compound most often underdosed or swapped for something cheaper.
This review covers what users report, the lab evidence, how GP Oxan is used by men and women, how to check it, side effects and how it compares with other oxandrolone products. Oxandrolone is a controlled substance outside a prescription and carries liver and lipid risks.
Oxandrolone is the most faked oral on the market. The lab result on GP Oxan applies to the tested batch; a pouch from an unknown seller still needs checking.
Lab Evidence and User Reports
The SIMEC AG test, published by AnabolicLab in August 2015, is the main reason Geneza Pharmaceuticals Anavar has a good reputation. The report introduction describes a 50-tablet pouch labelled at 10 mg per tablet; the test was funded independently of any seller and found slightly more oxandrolone than the label states. The full report sits behind a membership, and it covers one batch from one source, which is the usual limit of community testing.
User reports on forums match the lab picture for this Geneza oxandrolone: dry strength gains, more vascularity, little water retention, and blood work showing the expected fall in HDL and SHBG within two to three weeks. Complaints are mostly about price and availability, since it costs more than the brand's injectables per week of use, and about fakes from unknown shops. The broader pattern of Geneza Pharmaceuticals reviews is in Geneza Pharmaceuticals reviews.
GP Oxan 10 mg vs GP Anavar 50
Geneza sells oxandrolone in two strengths, and mixing them up is the biggest dosing risk with this brand.
The two GP oxandrolone products
GP Oxan
10 mg per tablet
50 tablets
GP Anavar 50
50 mg per tablet
50 tablets
One GP Anavar 50 tablet holds as much oxandrolone as five 10 mg tablets. A woman used to half a 10 mg tablet, about 5 mg, would take ten times her usual dose from half a GP Anavar 50 tablet. The 50 mg version also cannot be split finely enough for the low doses women report, so it is aimed at men taking 50 mg a day in a single tablet. The 2015 lab test covered the 10 mg product only; GP Anavar 50 has no public testing, so the usual checks apply to it with more weight.
What Clinical Data Shows
Oxandrolone is one of the few anabolic steroids studied in controlled trials, mostly in older adults and burn patients. In a 12-week trial published in the Journal of Clinical Endocrinology and Metabolism in 2004, 20 men aged 60 to 87 took 20 mg a day of oxandrolone and 12 took a placebo. The oxandrolone group lost 1.8 kg of total fat, including 1.2 kg from the trunk, and most of that loss persisted 12 weeks after stopping. HDL cholesterol fell by 0.49 mmol/l, roughly 19 mg/dl, and LDL rose by 0.57 mmol/l; the lipid changes were largely reversed after the drug was stopped.
The trial dose of 20 mg a day sits at the low end of what men report, and the HDL fall at that dose is the same marker users rely on to confirm a real product on blood work.
How GP Oxan Is Used
Common oxandrolone use contexts reported by users
Women
5 to 10 mg
10 mg tablets split in half; virilisation risk rises with dose
Men, oral-only
30 to 50 mg
Suppressive on its own
Men, added to testosterone
20 to 50 mg
Most common use in cutting cycles
Course length
6 to 8 weeks
Longer courses raise liver and lipid strain
These are ranges users describe, not recommendations. Because Geneza Pharmaceuticals Anavar comes in 10 mg tablets, women typically split them for a 5 mg start, and some report uneven splitting, a problem with pressed tablets in general rather than with Geneza specifically. For the product that most often accompanies GP Oxan in a cycle, see GP Test Cyp 250.
Checking Geneza Pharmaceuticals Anavar
- 1Seller: buy only from a reseller with years of independent feedback. Fake oxandrolone is common and usually comes from new shops.
- 2Packaging: compare the pouch, print, batch and expiry format with recent community photos of the same batch.
- 3Tablets: consistent colour, size and imprint within the pouch; crumbling or mixed colours are warning signs.
- 4Reagent test: confirms oxandrolone rather than a cheaper substitute such as methandienone or stanozolol.
- 5Blood work: SHBG and HDL should fall noticeably within two to three weeks; no change at all is a red flag.
The step-by-step process is in the Geneza product authenticity guide.
Side Effects
Oxandrolone is milder than most orals but not harmless. Users report lower HDL and higher LDL, raised liver enzymes, suppression of natural testosterone in men, and for women voice deepening, clitoral enlargement and body hair growth, some of which can be permanent. Headaches, back pumps and reduced appetite also appear in logs. Blood work before, during and after a course, covering lipids, liver enzymes and for men testosterone, is the standard community advice.
GP Oxan vs Other Oxandrolone
How GP Oxan compares
GP Oxan
10 mg per tablet
SIMEC AG test, slightly above label
Dragon Pharma Anavar
10 or 50 mg per tablet
Community testing, maker-run scratch code
Unknown-brand Anavar
Varies
Often underdosed or substituted in community tests
The real gap is not between reputable brands but between a known source and an unknown one. The brand-level picture is in our Geneza Pharmaceuticals review.
A community-funded SIMEC AG analysis found GP Oxan slightly above its 10 mg oxandrolone label, and users report the expected drop in HDL and SHBG on blood work. That covers tested batches from known sources. Oxandrolone is heavily faked, so a pouch from an unknown seller still needs checking.
Each GP Oxan tablet is labelled 10 mg of oxandrolone, in a 50-tablet pouch; GP Anavar 50 is a separate 50 mg product. The lab test found slightly more than 10 mg per tablet. Women typically split tablets for 5 mg doses, and men take several tablets a day, often split into two doses because of the short half-life.
Women use GP Oxan more than any other Geneza product because oxandrolone is among the milder anabolics. Reported use is 5 to 10 mg a day for six to eight weeks. Virilising side effects such as voice changes can still occur and may be permanent, and risk rises with dose and duration.
Warning signs are an unknown seller, a price far below established stores, packaging that differs from recent batch photos, tablets that vary in colour or crumble, and no fall in HDL or SHBG on blood work after two to three weeks. A reagent test confirms the compound.
Lower HDL and higher LDL, raised liver enzymes, suppression of natural testosterone in men, and in women possible voice deepening, body hair growth and clitoral enlargement. Headaches, back pumps and appetite loss are also reported. Lipid and liver blood work before, during and after a course is standard advice.
Both have independent test evidence behind them and sit in the same tier. Dragon Pharma offers a scratch code on its own site, while GP Oxan has a published SIMEC AG result above label. The seller matters more than the brand: either one from an unknown shop carries the same risk.
