Executive Summary

Exploration of special ingredients fisters add to lubes to create unique sensations within the hole. Includes classification strategies, related health concerns, and general protocols associated with additives. Also includes a full index of over 30 additives that identifies functional properties, specific usage and prep tips, and any concerns or considerations for each included additive.

Additive Classifications

A lubrication apothecary is an eclectic collection of ingredients that can be carefully blended to create fisting lube.

Additives from the apothecary can trigger novel sensations within the hole; heighten or diminish tissue sensitivity; and stimulate other senses during a fisting session. They can also prolong lubricity, alter viscosity, and extend shelf life.

There are multiple ways to sort and organize additives within an apothecary. Fist Theory uses two cataloging conventions:

  • Derivation | Refers to the origin of the additive. It includes four sub-classifications: tincture, cosmetic, pharmaceutical, and supplemental bases.
  • Functionality | Refers to the functional characteristics introduced by the additive.
QUICK REFERENCE

Figure 1.1: Lubrication Apothecary

Nostalgic apothecary store front serves as inspiration for the artisanal lubes created by blending traditional lubrication bases with various additives.

Derivation

Fist Theory uses the term derivation to categorize additives by their composition or source.

Tinctures

A tincture is a concentrated liquid extract of herbs, plants, or medicinal substances, often taking the form of aromatic oils. A few drops of a tincture added to a batch of fisting lube can generate a warm or cool sensation within the fist chute that may potentially be accompanied by a mild numbing effect for prolonged play.

Many tinctures are marketed as essential oils. The claims associated with these oils often lack robust scientific data regarding their efficacy. Some offer only a placebo effect.

Tinctures can be purchased online or at health food stores.

Small Stack of Unrefined Clove
Figure 1.2: Unrefined Clove

Clove oil is derived from clove and is one of the most common lubrication additives. It is both highly aromatic and highly allergenic.

Tinctures, like all other additives are not inert. They can trigger allergic reactions in small quantities. In large quantities, they can cause direct damage to mucosal tissue. They should never be applied directly to the fist chute in concentrated form.

Pharmaceuticals

Pharmaceutical additives include non-prescription medications, prescription medications, and illicit drugs.

The most common pharmaceutical additives are non-prescription creams or ointments that provide analgesic properties. Menthol, which may have a minty aroma and may trigger a warm sensation, is typically the active ingredient in most of these additives.

Lidocaine Anorectal Cream
Figure 1.3: Lidocaine Anorectal Cream

Some pharmaceuticals are specifically formulated for the rectum and anal canal.

Less common pharmaceutical additives include reparative medications, such hemorrhoidal creams that soothe the tissue of the fist chute and promote healing with specific vitamin complexes.

Common examples of pharmaceutical additives include topical Diclofenac gel (Voltaren Cream), lidocaine, and phenylephrine and pramoxine (Preparation H).

Cosmetics

Both the fist chute and fisting lube are altered by cosmetic additives.

Lube modifications include changes to the texture and aroma of a lubrication.

Chute modifications include how the intestinal tissues interact with fluids from the lube. The cosmetic's active ingredients coat the fist chute with a film that decreases fluid absorption rate and can even draw moisture into the chute from nearby tissue.

QUICK REFERENCE

Additionally, cosmetics have ingredients that may extend the shelf life of lubes.

Aqueous Cream
Figure 1.4: Aqueous Cream by Boots Pharmacy

The active ingredients in some cosmetic products, such as Aqueous Cream, prolong the lubricity of lubes by reducing the absorption of the moisture within lube inside the fist chute.

Traditional Bases

When more than one traditional base is used in the preparation of lube, the proportions used will classify the base as an additive, a supplemental base, or a dual base.

These proportions and classifications are arbitrary. Fist Theory uses 15/85 and 50/50 as the identifying thresholds. When bases are used in the same proportions (50/50), they are dual bases. Any ratio less than 15/85 is considered an additive, while anything else is supplemental.

When two bases are used and the second base is an additive, only a few of its properties are manifest in the final concoction. For example, using a squirt of silicone lube in a recipe will increase a lube's shelf life, but will not have the distinct lubricity of pure silicone lube. In this case, the volume of silicone is less that 15%; therefore, it is considered an additive.

Figure 1.5 [ A - D ]: Secondary Bases Versus Bases as Additives

When two bases such as a PEO (X lube) and a lipid (Crisco) are used, the ratio determines if one of the bases functions as an additive or if it functions as a dual base.

VOCABULARY

Traditional Base

  1. Noun Phrase In single-base lubrication recipes, the only base; typically a lipid or alphabet lube

Dual Base

  1. Noun Phrase One of the two bases in recipes with bases mixed together in equal proportions (50/50)

Supplemental Base

  1. Noun Phrase In recipes with multiple bases, any base that is less than 50% percent of the base ratio but greater than 15% of the base ratio.

Functional Properties

Additives can be categorized according to the properties they introduce to the lubrication. These properties generally fall into four categories:

  • Physical | Includes properties observed by the physical senses: sight, smell, taste, and touch.
  • Physiological/Sensory | Introduces sensations within the hole such as numbing, temperature perception, and anti-inflammation.
  • Neurological | Modifies brain chemistry and alters perceptive abilities.
  • Antimicrobial | Decreases rapid colonization by microbials and may reduce the spread of infections.

Some additives are very limited in scope and introduce a single functional property. Other additives are very potent and introduce multiple properties. For example, Clove adds thermal properties, antimicrobial properties, aromatic properties, anti-inflammatory properties and analgesic properties.

Physical Properties

In most cases, additives are used to create physiological responses within the hole. For example, menthol is often used to numb the fist chute, but it may also modify the lube's scent, flavor, color, and texture. Physical changes are often unintentional and include:

  • Scent (Aromatic) | Scent changes are usually introduced by additives that have analgesic or anti-inflammatory properties. Clove, which smells woodsy with hints of ginger, is added to numb the hole, decrease inflammation, trigger a tingling sensation, and hamper microbial growth.
  • Taste (Gustative) | Taste and smell are closely linked senses. As such, taste changes often occur with scent changes. In some cases, specific flavor profiles can be added, such as strawberry or cherry. In other cases, general gustative receptors are activated (saltiness, bitterness, sweetness, sourness, or meatiness).
  • Feel (Texture/Consistency) | Texture modification is frequently caused when a second base is used as an additive. Dual-based lubes usually feel silkier than single-base lubes.
  • Look (Appearance/Coloration) | With the exception of luminescent additives, changes in appearance (usually opacity) are byproducts of other additive changes. Adding color that masks bleeding is not recommended.

Figure 1.6 [ A - F ]: Physical Properties of Additives

Additives can change the way we perceive lube, including coloration, odor, texture, and taste.

Physiological Properties

Additives are primarily* used to improve fisting experiences by altering physiological responses to stimuli. These types of additives can be grouped into three general categories:

  • Therapeutic | These additives provide relief to tissues damaged by fisting:
    • Anti-inflammatories decrease swelling by suppressing prostaglandins; pain decreases as a result
    • Reparatives supply materials that help repair irritated tissues
    Common examples of reparatives include clove and Vitamin E.
  • Analgesics | These additives block transmission of pain signals to the brain.
  • Somatic | These additives stimulate nerves and trigger rapid signals to the brain. In some cases, the end result is pleasurable, and, in some cases, the end result is irritable. Common manifestations include:
    • Thermal Perception (sensations of warmth or coolness)
    • Paresthesia (tingling)

* Changes to physical properties and extending shelf life are usually secondary considerations of additives.

Figure 1.7 [ A - C ]: Physiological Effects of Additives

Additives can affect how the fist chute reacts to fisting, including suppressing inflammation, blocking pain, and stimulating chemical receptors that trigger tingling or temperature sensation.

Antimicrobial Properties

Certain additives may slow microbial growth in lubes; however, there are very few studies related to antimicrobial ingredients used in rectal intercourse. Available studies document the difficulty of assessing infections related to lubrications.1

Neurological Properties

Some chem fisters mix illicit drugs into their lubrications that alter mental states.

QUICK REFERENCE

Apart from overdosing concerns related to bypassing first-pass metabolism, some substances, especially crystal meth (T), weaken, destroy, and scar the mucosal membrane. A compromised membrane increases perforation risks.

The active ingredients in marijuana oils (CBD and THC) may have other medicinal values beyond alteration of mental status but should be used with caution.

Health Considerations

Additives, by definition, are not inert. Fisters utilize them to alter the way cells and tissues function. At a cellular level, they can have detrimental health consequences including allergic responses, tissue damage, diminished organ function, and cancer. They can also increase injuries from risky activities and behavior.

Tissue and Organ Damage

Pharmaceutical additives contain many compounds that are "harmless" to skin cells but are fairly toxic to more sensitive cells inside the body. When these compounds are absorbed through the rectum and colon, they bypass evolutionary mechanisms that decrease their potency. These compounds wreak havoc on various organ systems:

  • Rectum and Colon | Direct exposure to caustic agents can cause burns and may weaken the intestinal lining. This increases the likelihood for tears, perforation, and cancer mutations. Additionally, anesthetic additives may decrease sensation and increase mechanical injuries from fisting itself, including tearing, bruising, and excessive tissue sloughing.
  • Kidneys | Nephrons, the functional unit of the kidney, are damaged while attempting to excrete certain additive agents. Additionally, the kidneys can be damaged by rapid changes in blood velocity.
  • Heart and Blood Vessels | Rapidly dilating and constricting vessels occur as the body is exposed to certain additives and the hormones that the body uses in an attempt to regulate the effects of additives. Increased risk of vessel damage, vessel blockage, and heart attack are possible outcomes.
  • Liver | Active ingredients that were not initially catabolized in the small intestine can trigger damage to liver cells. Permanent liver cell damage (cirrhosis) occurs with inflammation triggered as the liver metabolizes toxic agents.

Many of the tinctures added to fisting lubricants are known for their antimicrobial, anti-inflammatory, analgesic, or mild preservative properties. However, the amount required for these effects is much greater than what the sensitive tissues of the rectum and colon can safely tolerate. For instance, to meaningfully prevent microbial contamination, an additive would typically need to make up 1–5% of the total volume of the lubricant. In contrast, most recipes include only a few drops—usually less than 0.01% of the mix. While such trace amounts may offer minor short-term antimicrobial effects, they provide little lasting protection. Increasing the dose enough to be effective would instead risk irritation, burning, or even chemical injury to mucosal tissue. The charts and tables in this course describe the functional properties of various lubrication additives, but it’s important to remember that these benefits may not be apparent in your formulation when the tincture’s concentration is too low relative to the total volume.

Allergic Reactions

Lubrication and additives absorbed directly into the bloodstream can trigger unexpected immune responses.

Once the immune system encounters unexpected molecules, it will begin creating antigens to attack and remove potentially harmful invaders. In most cases, the immune response is minimal. In other cases, rashes, itching, swelling, fatigue and malaise may all be manifested.

Compromised Judgement

Additives can affect judgement and increase risk tolerance through psychological, physical, or physiological means:

  • Physiological | Chems used as additives can alter cognitive processing centers of the brain. Pain is often masked. Stimulated pleasure centers within the brain encourage fisters to 1) extend sessions beyond rationale session durations, and 2) attempt riskier fisting activities such as extreme depth play.
  • Physical | Analgesic, somatic, and anti-inflammatory additives may decrease pain or the perception of pain. This decrease allows fisters to continue playing when normally they would stop activities that are causing injury to the fist chute.
  • Psychological | Placebo effects with additives are common. Myths and misinformation provide false courage, which often leads to attempting advanced activities beyond the hole's present capabilities.

Fister's with increased risk tolerance are more likely to engage in extreme fisting, including advanced depth exploration, rapid pistoning, intense stretching, and vigorous punch play. These activities usually require months or years of hole conditioning to execute safely without injury.

Off-label Usage

Most additives are topical and are not formulated for rectal use. Very few studies exist regarding rectal application in quantities associated with fisting. With that in mind, consider the following regarding frequently used additives:

  • Dosage | When formulating topicals for skin, manufacturers must increase dosages to accommodate for loss due to skin impermeability. In other words, they must include higher dosages of active ingredients because your external skin only absorbs a small percentage of those ingredients. You may be inadvertently overdosing when using rectally.
  • Route | When a topical is absorbed rectally, there is no first-pass effect to reduce existing dosages to non-toxic levels. You may be causing substantial kidney and liver damage.
  • Studies and Tests | There are few studies that evaluate harmful side effects of rectal use. Those studies that do exist do not typically consider the quantity of additive used with fisting and thus, do not give accurate data regarding health effects.
Applying Voltaren Incorrectly
Figure 2.1: Incorrect Application Strategy

According to the manufacturer, you shouldn't apply Voltaren gel with a bare hand due to concerns regarding excess absorption in a specific area.

Case Study: Off-label Usage of Voltaren Gel

A common additive used by many fisters is Voltaren Gel. The generic name for Voltaren gel/cream is diclofenac sodium.

Diclofenac is an NSAID (like ibuprofen) and thus, nephrotoxic at high levels. Oral diclofenac interacts with dozens of medications and older literature suggests links to heart attacks and strokes (although these symptoms are not listed in current US databases).

The manufacturer indicates only 6% of the active ingredient is absorbed through the skin, prohibits application of more than eight grams to a single area within a 24-hour period, and limits total application to just 32 grams per day. Absorption in the rectum is much higher than 6%, so the limitations set for topical application are too large. Cutting recommended daily allowances in half is highly problematic.

Fisters use about 5 grams for hole application and up to 15 grams (15 mL / 1 tablespoon) in lube application. Based on rectal absorption rates compared to skin, this exceeds recommended allowances. The likelihood of absorbing enough of diclofenac sodium to cause noticeable kidney damage and severe side effects with long term use is elevated, especially with no first-pass effect.

Diclofenac Gel

Diclofenac gel is a powerful anti-inflammatory ointment with mild numbing properties, meant for topical use only. Voltaren Cream and Solaraze Cream are non-generic forms of diclofenac gel.

A small dollop in the fist chute exceeds dosing limitations and will cause long term damage.

The manufacturer's label suggests no more than 32 grams be applied to skin cells daily and forbids internal use. Of the 32 grams in use, only 6% is absorbed in the skin due to the thick, layered nature of skin cells. In comparison, mucosal tissue of the fist chute will absorb significantly more. Assuming that the fist chute absorbs 50%, one fingernail-size dab is risky. Six percent of 32 grams is about 1.5 grams which is roughly 1-2 milliliters—about a small fingernail size dab.

Witch Hazel (Liquid, Cream)

Witch hazel is made from the twigs and bark of Hamamelis virginiana, the witch hazel shrub. It is often used for hemorrhoidal treatment by reducing swelling and constricting blood vessels; however, this ability comes with an intense sting, similar to when hydrogen peroxide or alcohol is poured on an open wound. Pure witch hazel is a liquid that can be purchased at drugstores and pharmacies.
