Dosing for MT2 is highly individualized and depends on your goals (tanning only, libido effects, etc.), skin type, and sensitivity to side effects.
A typical dosing protocol for tanning purposes often follows a "loading phase" and then a "maintenance phase."
1. The "Loading" Phase (First 10-14 Days)
The goal here is to saturate the receptors in your body to stimulate melanin production.
●Starting Dose: Most people begin with a very low dose to assess their tolerance to side effects (primarily nausea). A common starting point is 0.25 mg (250 mcg).
●Administration: This is injected subcutaneously (into the fat under the skin, like insulin) once per day.
●Assessing Tolerance: If you experience minimal nausea, you can gradually increase the dose every 1-2 days.
●Target Loading Dose: Many users work up to a daily dose of 0.5 mg (500 mcg) during this phase. Some may go slightly higher, but it is not recommended to exceed 1 mg per day due to a significant increase in side effects.
2. The Maintenance Phase (Ongoing)
Once you have achieved your desired level of tan, you switch to a maintenance dose to sustain it.
●Dose: The maintenance dose is typically 1-2 injections per week.
●Amount: The amount per injection can vary but is often between 0.25 mg to 0.5 mg (250 - 500 mcg).
●Important: The frequency and amount needed are highly personal. Some people can maintain a tan with just one 0.25 mg injection per week, while others may need more.
Critical Considerations and Warnings
Before you even consider dosing, you must be aware of these factors:
1. Significant Side Effects
●Common & Immediate: Nausea is the most frequent side effect, often accompanied by facial flushing, loss of appetite, and yawning. These usually subside after the first week or as your body adjusts.
●Concerning: Spontaneous erections (in men) and increased libido are very common due to the peptide's effect on the brain. This is a known pharmacological effect, not an anomaly.
●Serious & Long-Term:
○Hyperpigmentation: This includes new moles and freckles (often dark) appearing or existing ones getting darker. This can be permanent.
○Risk of Melanoma: The long-term cancer risk is unknown. MT2 stimulates all melanin-producing cells, including potentially cancerous ones. If you have a personal or family history of melanoma, this is an absolute contraindication.
○Vision Changes: It can cause retinal darkening, which is a theoretical risk to eye health.
○Kidney Damage: There is evidence from animal studies that it can cause renal toxicity.
2. Dosing Accuracy is Paramount
MT2 is typically sold in vials as a dry powder (e.g., 10 mg). You must reconstitute it with bacteriostatic water.
●This is not a simple process. You must know how to calculate the concentration so that your injections are accurate. An error can lead to a massive overdose.
○Example: If you mix 10 mg of MT2 with 2 ml of water, then every 0.05 ml (or 5 "units" on an insulin syringe) will contain 0.25 mg (250 mcg).
3. Sun Exposure is Required (But Must Be Controlled)
●MT2 does not work without UV stimulus. You must have sun exposure or use a tanning bed for it to trigger the tanning effect.
●WARNING: Because MT2 dramatically increases your skin's sensitivity to UV light, it is extremely easy to burn. You must drastically reduce your UV exposure time (e.g., start with 2-5 minutes in a tanning bed or 10-15 minutes in the sun) and gradually increase it.
