What are PIs?

If you stopped thinking about penis enlargement pills, enlargement surgeries, or weird incantations to get a few extra inches down there, but you still want to learn how to make your dick bigger, Penis Enlargement is the way to go.


Penis Enlargement is a whole world, and learning from this practice requires time, reading, and commitment. If you have already read about Penis Manual exercises, Vacuum Penis Pumps, Penis extenders such as Phallosan, or even Penis Weights (Hanging), this article will be very useful to evaluate the result of your training and the methods you are using. Today we are going to talk about PIs or physiological indicators.



This term was initially coined by a PE practitioner on the worldwide famous PE forum, Thundersplace. It spread and became part of the practice's terminology. The physiological indicators refer to the series of signs that we can notice in our body, which indicate the effectiveness or otherwise of our training.


This system can be interpreted as language from signals we get from our bodies. It is essential always to be attentive and to listen to what our body is telling us. In Penis Enlargement, whether you practice manual exercises such as Jelqing, if you use a Bathmate, or if you practice Penis Hanging, it is essential to pay attention to the signs and not rush. Don’t put too much pressure on the endurance capacity of your member because you only have one! So know your limits!


If you want to make your dick bigger, it requires a lot of patience and listening. These are the elements that make an effective but safe Penis Enlargement practice.


They can be divided into negative PIs, positive PIs, and neutral PIs.


  • The appearance of negative PIs signifies that you are overtraining your member and need to reduce the time or force applied.

  • Positive PIs are an excellent sign of your training sessions’ effectiveness or improvements in your technique.

  • Neutral PIs are not positive or negative and must be interpreted in relation to other positive or negative PIs. Therefore, if negative signs have appeared alongside these signs, it is better to take precautions. On the other hand, there is no reason to be alarmed if a neutral PI appears alongside a positive PI.



Negative PIs:


  • Pain

  • Decrease in the frequency of spontaneous night and day erections

  • The reduced hardness of erections

  • Numbness

  • Discoloration

  • Loss in size

  • Donut Effect


Positive PIs:


  • A larger flaccid size that lasts all-day

  • Increased frequency of spontaneous night and day erections

  • Increased hardness of erections

  • Increased erect size


Neutral PIs:


  • Temporary contraction of the penis after PE exercises

  • Flushing

  • Stains

  • Slight pain in the penis

  • Temporary increase in size, from a few minutes to a couple of hours

  • Edema under the skin of the penis


Of all the PIs, the gain or loss in size is the most important.


The loss or gain in size will give you the final say as to whether or not your routine has been effective for you.


An effective way to reduce the possibility of negative or neutral PIs appearing during or after training is to use your Jelqing Balm as an indispensable weapon in your PE arsenal. We designed JELQ2GROW’s Jelqing Balm for serious PE practitioners. Use it before, during, and/or after your manual exercises session (Jelqing, Stretching, Edging) or if you’re training with devices (Pumps, Weights, All Day Stretchers).
