It's not surprising a squirter is going to tell you it's not fake and it's not pee. If they did their clients would be reduced to those wanting golden showers. However, the fluid expelled by a squirter has characteristics of urine. The female prostate gland is very small, yet a squirter can expel up to 2 cups of fluid. Anatomically, where is the closest place this amount of liquid can be produced and stored? Answer: The Bladder.
Here is an interesting article on "Female Ejaculation, The G-Spot and The Female Prostate Gland."

Relation to urinary incontinence
Towards the later part of the twentieth century, there was significant confusion between female ejaculation and urinary incontinence. In 1982, Bohlen explained the accepted wisdom;[33]
The previously accepted notion that all fluid expelled during a woman's orgasm is urine is now being challenged...sexologists must take care not to assume now that any fluid produced at orgasm is "female ejaculate".
Scientific studies from the 1980s and later have demonstrated that the substance produced is distinct from urine, though it does show similarities such as alkalinity with urine.[7] A recent study of women who report ejaculation found no evidence of any urological problems, suggesting these two conditions (ejaculation and coital incontinence) are quite distinct physiologically, although perhaps not always distinguishable in a particular individual's mind.[citation needed] Davidson's study of 1,289 women found that the sensation of ejaculation was very similar to that of urination.[3]
The best evidence indicates that most fluid expelled during female orgasm is urine. One study used urethral catheterization in order to separate urine from orgasmic expulsions from elsewhere in the body. Seven women claiming to have ejaculations expelled large volumes of urine through the catheter at orgasm, and little to no other fluid.[61] No catheterization study has shown large volumes of fluid expelled at orgasm from any source other than the bladder.
It may be important for physicians to establish whether there is in fact any incontinence in women who report ejaculation, to avoid unnecessary interventions.[32][62] It is also important for physicians to distinguish orgasmic ejaculation from vaginal discharges which may require further investigation and treatment. In individual cases, the exact source of any reported discharge may not be obvious without further investigation.
Nature of fluid
Critics have maintained that ejaculation is either stress incontinence or vaginal lubrication. Research in this area has concentrated almost exclusively on attempts to prove that the ejaculate is not urine,[43][63] measuring substances such as urea, creatinine, prostatic acid phosphatase (PAP), prostate specific antigen (PSA),[6] glucose and fructose [64] levels. Early work was contradictory; the initial study on one woman by Addiego and colleagues reported in 1981,[30] could not be confirmed in a subsequent study on 11 women in 1983, [65] but was confirmed in another 7 women in 1984.[66] In 1985 a different group studied 27 women, and found only urine,[46] suggesting that results depend critically on the methods used.
A 2007 study on two women involved ultrasound, endoscopy, and biochemical analysis of fluid. The ejaculate was compared to pre-orgasmic urine from the same woman, and also to published data on male ejaculate. In both women, higher levels of PSA, PAP, and glucose but lower levels of creatinine were found in the ejaculate than the urine. PSA levels were comparable to those in males.[5]
Source of fluid
One very practical objection relates to the reported volumes ejaculated since this fluid must be stored somewhere in the pelvis, of which the urinary bladder is the largest source. The actual volume of the para-urethral tissue is quite small. By comparison, male ejaculate varies from 0.2–6.6 mL (0.04–1.3 tsp) (95% confidence interval), with a maximum of 13 mL (2.6 tsp).[67] Therefore claims of larger amounts of ejaculate are likely to contain at least some amount of urine. The eleven specimens analyzed by Goldberg in 1983,[65] ranged from 3–15 mL (0.6–3.0 tsp).[66] One source states that Skene's glands are capable of excreting 30–50 mL (6–10 tsp) in 30–50 seconds,[54] but it is unclear how this was measured and has not been confirmed. One approach is to use a chemical like methylene blue so that any urinary component can be detected.[66] Belzer showed that in one woman he studied, the dye was found in her urine, but not her orgasmic expulsion.[29]
PAP and PSA have been identified in the para-urethral tissues, using biochemical and immunohistochemical methods, suggesting that the ejaculate likely arises from the ducts in these tissues, in a manner homologous to that in the male.[68][69][70][71][72] Another marker common to the prostate/para-urethral tissue in both sexes is Human Protein 1.[73]
PSA occurs in urine, and is elevated in post-orgasmic samples compared to pre-orgasmic. Simultaneous collection of ejaculate also showed PSA in both urine and ejaculate in all cases, but in higher concentration in the ejaculate than in the urine.[50]
Function
The physiological function of the purported liquid is unknown. A 2009 paper in Medical Hypotheses suggests that it may have an anti-microbial function, protecting from urinary tract infections.[74]
