The doctor was fantastic
I was feeling worn down, not my normal self. I didn't feel like my old energetic self in the gym or my personal life. I saw Maximus on Insta, and thought I would do some research. I had my blood work done and found my testosterone at 350. I decided to have a consultation, The doctor was fantastic and recommended Enciclophine, so I said let's try it. What a difference it made. My testosterone went up to 700. It has made a huge difference for me. I highly recommend Maximus if you're considering options for raising your Testosterone levels- give them a try. The whole process was a breeze.

My testosterone level was already good…
My testosterone level was already good for a man my age, but my level now puts me at the 99th percentile for all men, and I turn 66 next month. I am stronger at the gym, complete my workout routine faster, and my sleep is better regulated. My resting heart rate has dropped 10 points and is close to my best all time. I have not pushed myself as I should have so am giving it another 3 months to supercharge my results. It has delivered as promised with no negative side effects.

The whole experience was just…
The whole experience was just shockingly good. I was shocked to see how low my testosterone levels were and then shocked again how much better I felt after taking my personalized recommendation.

The results have been life changing
My experience with Maximus has been next level. To start, their at-home test kits are easily the best on the market as they utilize the Tasso collection device that is painless and provides enough blood for high accuracy when sent off to the lab. I have been utilizing 12.5mg enclomiphene daily and the results have been life changing. After about a month of daily use, both my total T and free T almost doubled (340 to 601 and 72 to 134 respectively). Been feeling more level headed, have increased confidence, and have gained a bit of lean mass. Their support team is great and promptly assisted with an issue I had on their portal. The discord community is also an excellent resource and support group with the staff and founder of the company active almost every day. If you are looking to optimize your life, Maximus is an easy recommendation!

Can I take Blood Flow Protocol, even if I don’t have ED?
Most men are potentially eligible for and could benefit from Sexual Enhancement Protocol given the formulation and dosage are optimized for daily use.
Even if you are not experiencing ED, Sexual Enhancement Protocol can improve your sexual drive, endurance, and satisfaction. Sexual Enhancement Protocol also increases blood flow, which improves gym performance (better muscle pumps and less muscle fatigue) and mental function (improved attention, memory, & processing speed).
How is Blood Flow Protocol different from generic ED medications?
Most generic ED medications are one pharmaceutical that only improves blood flow, which is a plus for men who struggle gaining and keeping an erection.
Sexual Enhancement Protocol is a synergistic combination of two medications, which increases blood flow better than ED medication alone, while also working through the central nervous system to elevate sexual drive, endurance, and satisfaction.
Unlike some ED medications which come in high dosages designed for occasional use, Sexual Enhancement Protocol is formulated for safe daily use, and has an effect that builds up over time.
What is the cost and what’s included?
The treatment cost for Blood Flow Protocol starts at $99.99/month for our 2.5 mg tadalafil, + 2.5 mg vardenafil formulation. It is $149.99/month for our 5mg tadalafil + 5mg vardenafil formulation.
The pricing for our 10mg tadalafil + 10mg vardenafil formulation is as follows:
4 doses $59.99
8 doses $109.99
12 doses $159.99
What are the benefits of daily use?
The convenience of always being ready for sex, anytime. No need to plan ahead – enjoy the pleasure of spontaneity.
The sexual drive, gym performance, and mental function enhancing effects accumulate over time from daily use.
Does Blood Flow Protocol have adverse side effects?
General adverse effects
The adverse effects of 5 mg daily use of tadalafil have been extensively studies in placebo-controlled clinical trials. The drug is generally well-tolerated, however infrequent side effects may occur such as:
— Headache (observed in 6% of patients)
— Dyspepsia (observed in 5% of patients)
— Nasopharyngitis (observed in 3% of patients)
— Back pain (observed in 3% of patients)
— Upper respiratory tract infection (observed in 3% of patients)
— Flushing (observed in 3% of patients)
— Myalgia (observed in 2% of patients) ¹
Being treated by a licensed doctor who is able to monitor your personal experience and customize your treatment protocol ensures you are able to experience the benefits with minimized risk of adverse effects.

Disclaimer: Erectile Dysfunction Treatment: HSA Eligibility
ERECTILE DYSFUNCTION TREATMENT: REQUIRES A PRESCRIPTION TO BE ELIGIBLE WITH A HEALTH SAVINGS ACCOUNT (HSA)
Erectile dysfunction treatment medicines are eligible and may qualify for reimbursement with a prescription with a flexible spending account (FSA), health savings account (HSA), or a health reimbursement arrangement (HRA). Erectile dysfunction treatment medicines are not eligible for reimbursement with a dependent care flexible spending account (DCFSA) or a limited-purpose flexible spending account (LPFSA).
What are erectile dysfunction treatment medicines?
There are several types of medicine available for the treatment of erectile dysfunction. Erectile dysfunction can be the result of a variety of different medical conditions related to the brain, nerves, muscles, and blood vessels. Stress and mental health concerns can exacerbate or worsen these issues, or cause erectile dysfunction separately (Urology Care Foundation).
Medicines for the treatment of erectile dysfunction include pills that increase the effect of nitric oxide which aids in obtaining an erection due to sexual stimulation. Other forms of medication include injections, urethral suppositories, testosterone hormone replacement therapies, penis pumps, penile implants, and blood vessel surgeries (Mayo Clinic).
A psychologist or counselor may also aid in treating erectile dysfunction that is a result of a psychological or mental health condition. Regardless of which treatment medicine is used, a prescription must be obtained for reimbursement eligibility under a consumer-directed savings account.
A doctor will likely recommend a specific treatment. Some erectile dysfunction treatment medicines have adverse side effects, and may not begin working immediately. Most should not be used more than once per day. Many erectile dysfunction treatment medicines are affected by other medications and supplements, and complications may result.
Is there potential for hearing issues with PDE5 inhibitors?
While extremely rare, there have been a few reports of hearing issues, such as tinnitus, in individuals taking PDE5 inhibitors. However, it's important to note that the FDA has not found a direct causal link between the use of PDE5 inhibitors and these hearing issues. These instances are very rare, and the overall risk is considered to be very low. If you experience any hearing changes while taking this medication, consult your provider immediately.
