Amount of Filler Required
Most patients take 10 to 20ml
The more filler used, the larger the result.
A longer penis will generally require more filler than a shorter penis.
Thickness Increase Estimate 20ml
Flaccid penis length is also increased by the procedure.
The weight of the filler and a scaffolding effect reduce penile retraction after losing an erection (resulting in less shrinkage from erect to flaccid).
Procedure Price
The cost of the procedure depends on the amount of filler used and the quality of the filler. The more filler injected, the larger the result.
Hyaluronic acid Fillers
Safe and reversible fillers based on a natural substance. Estimated 12-24 months half-life*.
Longer lasting fillers (Ellansé)
Collagen stimulator fillers such as Ellansé last up to 4 years, or more*.
Please enquire about our range of fillers. Additional detail on filler types and see special offers below.
*The estimated life of filler depends on the specific filler brand and factors specific to the patient. Results may vary from person to person. 15ml Androfill Premium is priced at £2,290 in Manchester.

Androfill Media Reports

Report from Martin, 32, Builder & Model.
Martin, who was single at the time after splitting up with his wife admits his insecurity had a negative impact on relationships.
But when Martin stumbled across the Androfill clinic online, it was a turning point. He says: “I spoke to them and they said I was well above average in length. But from their research, they said women seem to focus on girth and I could try the fillers.”
Martin, from Essex, has now had the procedure three times and has gone from a girth of around five inches when flaccid, to more than six.
“My missus says she can definitely tell and can feel the difference. She’s had her boobs done and I see it as being sort of the same thing.”

Penis Enlargement Injections FAQs
Description of the Procedure
The simplicity of the Androfill procedure opens up penis enlargement to a range of men who would not previously have considered it or are put off by the idea of invasive surgery.
When using a reversible dermal filler such as Hyaluronic acid, the procedure is no riskier than having filler injected elsewhere in the body, such as in the lips or face.
The penis is thickened by the injection of a Hyaluronic acid dermal filler which provides an immediate increase in penis girth and flaccid length. Being naturally produced by the body, side effects of the substance are rare, and the procedure is reversible by dissolving the filler if ever this is desired.
There are three steps:
1. A 30-minute consultation with our doctor.
2. If the patient wishes to proceed, a topical anaesthetic cream is applied, and the filler is injected into the penis.
As soon as the filler is injected, the penis becomes thicker.
3. Abstain from heavy lifting for 1 week and from sex for 2 weeks.
The patient can have the consultation and the procedure completed in as little as 1 hour, including the 30 minute consultation time.
Patient-doctor confidentiality is strictly adhered to.
Due to the quick recovery time, it is your choice whether you wish to inform your partner about the treatment.

Range of Androfill Patients

I always wondered what it would be like to be a bit bigger. My wife and I have grown children and now it's time to focus a bit on ourselves. My wife gets filler in her face, so I told her that I would be getting some filler too.

Gym Goer
After thousands of hours in the gym, I've got the body I want, except there is nothing I can do at the gym for my penis size. I want to feel as good about my penis as I do about the rest of my body.

Successful Businessman
I have all the trappings of wealth, a beautiful wife, sports cars, and a luxury house. Spending £3,000 on a bigger penis would make me feel happier than spending £300,000 on another car or boat.

Relationship Breakup
I recently broke up with my partner who said a few negative things about my body. My confidence is low and I want a bit of a boost before I join the dating market.

Family Man
After three children, my wife doesn't feel as tight anymore. I know the sensation isn't as intense as it used to be, and she feels the same. We talked about vaginal tightening procedures but then I discovered Androfill and thought it would be easier for me to thicken my penis than for her to have surgery.

Normal Guy
I've got a good size penis, but I wouldn't mind if it was a bit thicker. I have some spare cash so I'm going to go for it.

Small Size
For my whole life I have hated having a small penis, it started in school when the other kids pointed out how small I was. I have carried this feeling around with me for many years. Now that I have the money I would like to do something about my penis size, if only so that I can stop wasting time thinking about it.

Young Couple
My partner and I have an active sex life which includes sex toys and also penis pumps however the effect is temporary. We want to experience sex with a larger penis. I want my Androfill penis to be the same size as when I am pumped.
Penis Enlargement Injections FAQs
The Philosophy behind Androfill
The desire for a larger penis.
Put simply; more often than not, men would like to have a larger penis.
The results of a recent YouGov poll have been interpreted as follows:
“In Britain, being unhappy with your penis size is now the default situation for young men: more 18-to-24-year-old British men say they would like their penis to be larger (42%).”
“For men, the top modifications among those who would like cosmetic surgery are fat reduction (48%), penis enlargement (29%) and nose reshaping (19%).”
Providing a safe and effective option.
As increasing penis thickness has become a safe and simple procedure, there is no reason not to make this procedure more readily available to men.
Aside from making men happier about their penis size, we also hope to prevent:
- Unnecessary penopasty surgery. Read the NHS position on penoplasty here;
- The risk and costs involved in the consumption of penis enlargement pills;
- The use of dangerous substances for penis enlargement such as silicone, paraffin or mineral oil;
- Wasted time, cost, and effort involved in the use of various devices and penis exercise regimes;
- The breakdown of relationships that are blighted by genital size incompatibility or dissatisfaction in the bedroom.
The benefits.
Androfill Hyaluronic acid penis enlargement provides:
- Self-confidence, particularly for men with small or thin penises, but also to normally sized men, who simply wish to be a little thicker;
- For many, an improvement in the quality of relationships, as a result of an improvement in satisfaction with sex in some cases;
- Improved sensation for both partners during sexual intercourse, particularly if there is a mismatch in genital size, often after childbirth;
- A simple ego boost;
- A safer and more effective alternative to penis enlargement surgery;
- Relief from the anxiety felt by many males due to their penis size.

Filler Range
Recommended fillers for 1st-time patients are Androfill Premium and Voluma.
These fillers are hard and long-lasting, without being too hard for an inexperienced patient to mould.
Higher quality filler is harder and longer-lasting
Lower quality filler is softer and reabsorbs more quickly.
Filler price per ml £
Price / Quality
The price of Hyaluronic acid filler varies significantly according to the quality of the product.
Generally, more expensive fillers will feel more natural in the penis (firmer when erect), and will last longer.
A low-cost filler may have a lower price tag, but will not last as long or feel as natural.
Lower cost fillers should not be used. As time passes these fillers will start to feel ‘squishy’ or ‘padded’ when erect.
Androfill Premium and Voluma are excellent choices combining firmness with durability.
Repeat Androfill patients benefit from a £10 per ml reduction in filler price.

Budget Filler Problems
Budget Filler Problems
Budget Hyaluronic Fillers
As dermal filler penis enlargement has gained popularity, a number of clinics have tried to copy Androfill.
In order to have an advantage, these clinics are marketing budget or affordable fillers which are not suitable for the penis.
Budget fillers are generally softer and do not last as long as premium fillers. They are also more likely to have complications.
Patient’s can identify budget Hyaluronic acid fillers by the size of the syringe.
Syringes containing 10 ml of Hyaluronic acid are inexpensive and designed for larger body areas such as the buttocks.

These filers will feel softer and will break down into a ‘sloshy’ or ‘jelly’ feeling layer over time. If you prefer your penis to feel hard when erect, avoid budget or ‘affordable’ options.

Budget Filler Examples
GENEFILL CONTOUR / HYACORP
10 ml syringe body fillers
Commonly marketed as an ‘affordable’ option, Genefill is an excellent filler for the buttocks, however, it is not suitable for use in the penis.
This filler is commonly used by Androfill competitors because it costs around £8 per ml to purchase, compare that to around £140 per ml for Volux.
For a 15 ml procedure, the doctor using Genefill only has to spend £120 on filler. When using a harder product that is better suited to the penis the doctor will need to spend £2,100 (18x the amount). There is financial pressure on doctors to use cut-price fillers.
If you are being quoted a particularly low price for your filler procedure, it is most likely because the filler being used is lower grade.
Higher Risk in Genitals Clinical Evaluation
Contraindicated for Genital Augmentation
Must not be used in the penis.
